In this note, we’ll talk about promoting and further maintaining the server (aka print server) core server role in Windows Server 20xx, which will ensure effective, centralized control over the operation of all printers in the organization.

By installing the server together with the initial client installation of the printer, the following problems occur:

— Possibility of centralized management of all printers in the organization, including drivers.

— Ensure behind-the-scenes access to printers through publication in Active Directory;

— the ability to restart printers using group policy;

— Create bullets, which allows you to combine a number of physical printers into one logical one.

Our outputs are such that there is a large fleet of HP and Kyocera edge printers, and we need to establish access to them in such a way that users can independently select the printer closest to them and install them into the system. For this purpose, we, as administrators, need to start a separate server right away, add all our printers to a new one, publish them in Active Directory, teach users the simple steps of installing printer data, or install them in automatic mode for an additional group gender. ITICS. In the process of work, ignore the simple steps of system administration and identify problems that arise from the seal, as described below.

1) Install the Print and Document Services role ( Document service);

So, we are running a machine with Windows Server 2012R2 installed, although it can be 2008 and currently remain Windows Server 2016, because The process of installing a service from version to version does not vary much and only takes a few clicks on the Next button. Launchable Server Manager, select Add Role and Features Wizard(Add the role of component master).

Then we will continue with the first point Role-based or feature-based installation(Basic installation of roles and components) embossed Dali.

On the next screen Select Destination server We select a server from a pool or deployments on a VHD disk. Since we still only have one local server, we’ll call it Next.
Select a role for installation Print and Document Services, compatible with the installation of additional features - Print and Document Services Tools. Tisnemo Next.
On the next screen Features, optionally select components for installation as required. Tisnemo Next.

Let us then familiarize ourselves with the relevant information before serving our friend. Print and Document Services. Recognized and embossed Next:)

Then we select specific services for installation. Past Print Server(Server to your friend) you can vibrate Distributed Scan Server(Divisional scanning server), Internet Printing(Encouragement to a friend via the Internet) and LPD Service(Druku UNIX Service). Within the framework of this note, we will select the server to each other, select the one and press Next.

On the final screen, you will see the installed components that are selected by pressing the Install button.

Close the master for help close.

The same thing, aka Powershell, can be done in just a few commands:

Fipmo ServerManager add-WindowsFeature Print-Server

Once the service is installed, there is no need to restart the server. First of all, before you start adding printers to the server, add them to the domain so that you can publish printers directly to Active Directory.

Vikorist's classic gui option can be added, or with the help of an awkward command in PS:

Add-Computer -DomainName test.ru

Restart the server with the command:

Restart-Computer

2) Print Management console. Adding drivers and printers to the server;

Let's launch the Keruvan console Print Management. For whom let's go to Start\Administrative tools\Print management. Or we launch it in the command line: printmanagement.msc

Here, naive vuzol Print Management Allows you to add/receive local and other servers for administration, as well as printer migration.

Custom Filters filters printers by categories: All Printers, All Drivers, Printers Not Ready and Printers With Jobs. So, with the right button, you can set your own filter, if you don’t see the exact ones.

Print Servers displays the print server streams. In this section, you can see that we have only one (local) server for each other, where Drivers shows all the drivers on the streaming server for each other, Forms - all paper formats that are supported, Ports - local and edge ports for the streaming server for each other. , Printers - all installed printers on the other server.

Deployed Printers- Printers that have been turned on due to group policy violations.

To add a new printer to the server, go to the node Print Servers, select our local server prints (local) in the section Printers. Click the right button and select Add Printers. Start Printer Addition Master Network Printer Installation Wizard, which are the different installation methods. The first and best way to detect edge printers is to run the search in automatic mode. Search the network for printers, another point is the ability to add a TCP/IP printer or web printer for your IP address or host name. Add a TCP/IP or Web Services Printer by IP address or hostname, you will then be able to add a new printer to the same port Add a new printer using an existing port, and the last point is to connect your port with the further addition of a new printer. Create a new port and add a new printer.

If you select the first item and allow the master to add the printer in automatic mode, then the situation is wrong if the driver for the printer can be added automatically from the distribution of the operating system, which is not good, otherwise, the driver will be far from up-to-date, differently. You will be right under your printer model. Since there are not a lot of printers, there is no tragedy in it - everything will work out, except that we have a print server, which may depend on a number of devices, then we will sense the latest version of the driver from the virus website Nick. It is better to use a universal driver for several models in order to avoid any possible conflicts associated with the operation of many different devices on one server, and to reduce the time spent on May butnewly updated. You can read more about the advantages of the universal driver below.

And from all that has been said, it is clear that for the correct operation of the system, we first need to install the correct driver on the server, and then add the printers themselves. Therefore, we need a universal driver from the manufacturer’s website, for example for HP, and for Kyocera. Whatever the type of driver is, PCL5 or PCL6, then decide for yourself. Although PCL5 seems to be stable, I didn’t notice any particular difference. The idea behind PCL version 6 is simply a new implementation of the PCL driver from HP, so it can be sensed.

To add drivers to the console Print Management let's go to our local server at razdil Drivers And clicking the right button launches the Driver Addition Wizard. Add Driver. On the next screen, you select the type of processor architecture. If support for 32-bit client operating systems is necessary, then the x86 checkbox is also indicated. Tisnemo Dali.

On the screen Printer Driver Selection Select the driver for the printer. Tisnemo Have Diskі Browse To take a look at the addition of drivers.

We select the driver before selecting. Our application has a universal Kyocera driver, embossed Next and Finish. We repeat the operation for other devices.

Especially on my server, only HP and Kyocera printers are on the go, and drivers are used only by these printers. However, it should be noted that with the use of a universal driver from HP, not all printers are supported and all functions are supported correctly, although most corporate-class printers operate without problems. You can view the list of supported devices upon request. After adding the drivers, the approximate image will be displayed.

Let's look at the tab Driver Isolation(Isolation of the driver), de mi, the drivers for the promotion are designated by the ensign “shared” so. be in a special isolated regime with hidden access. Driver isolation technology or Printer Driver Isolation (PDI) Allows you to run printers in a continuous process. PrintIsolationHost.exe, besides the manager, spoolsv.exe and other drivers on the server, then. If the problem is in the driver, then it only kills the process that supports this driver, and not the service itself, spoolsv.exe, which results in a loss of productivity.

І In the shared mode (outside access), all printer drivers are configured to work with one, behind the scenes copy of the process PrintIsolationHost.exe, but not in front of the dispatcher. This mode is recommended by Microsoft. If you have problems with drivers, inconvenience, and frequent printer failures, especially in terminal mode, you can try using the isolated mode (isolation mode), even the printer driver, to adjust the vicor of your old copy to the process PrintIsolationHost.exe Also referred to as a spooler.

When the “none” option is installed, printer drivers must rely on the help of the spooler. When the spoolsv.exe process crashes, it stops working on all printers on the server.

Now, after adding the correct drivers, you can proceed to installing printers. To do this, we restart the already familiar Printer Addition Wizard, selecting to add a TCP/IP printer or web printer for your IP address. Then select the type of device: Auto detect - automatically selects parameters or TCP/IP Device, in the "host name or IP address" field enter the IP address of the printer. The checkbox “Auto detect the printer driver to use” is unchecked if it is active or unchecked. In this situation, the process of adding the “correct” driver does not interfere. Tisnemo Next.

On the next screen, select the HP or Kyocera universal driver from the list before installing it, or add a new one. Tisnemo Next.

Then, we set the name to the printer and add it to the back-end access, indicating the name of the shared resource, physical delivery and comment. With this information, customers can identify the required printer in the directory service and add it to their system. Tisnemo Next.

It is possible to install the printer accordingly. Click Next to indicate completion of the installation process.

In order for the printer to be available in Active Directory for selection, it must be published. To do this, go to the printer's Sharing tab and select the List in Directory checkbox and Apply.

We repeat the same operation for all printers in the organization. You can see all printers at a glance and right-click and say: List in Directory. From the result you can select the approximate upcoming list.

Now, on the client computer in the domain, you can get the required printer from the list and install it.

But this is theoretical, because it was like that before! In practice, when adding an edge printer under a domain cloud record, it is often possible to undo the following:

Connection to the printer. The policy installed on your computer does not allow connections until the end. Go back to the system administrator.

Or English version:

Connect to Printer. The policy is effective on your computer as long as you have accessed the print queue. Please contact your system administrator.

This is due to the fact that on June 12, 2016, Microsoft released the security update KB3170455, which addresses a critical problem with the system, which caused new improvements in the security of printer drivers, and itself:

1. The printer driver is responsible for trusting and signing with a digital signature. The installation process checks for the presence of hashed files in the driver package, and if it detects not hashed (without a digital signature), display a notification about the exchange of other policies. If you use a universal driver from HP, the verification of the digital signature of files in the package is successful and the printer is installed without problems, and when you try to install a printer from Kyocera on the client, the driver is tested with the Kyocera Universal Classic Driver, which, before speaking, is listed on the site to 'signed' vilazat vyshche.

2. The printer driver may be packaged, specification (package-aware v3). When you try to install a non-package-aware driver (non-package-aware v3), you will be prompted for permissions, which allows you to install the driver under an administrative account.

You can check the printer driver packages in the Printer Management console in the Drivers section, Packages column. As a matter of fact, the Konica Minolta driver is set to false.

If the problem arises from the installation of untrusted printer drivers on client computers, we can help by enabling the group policy: Point and Print Restriction, which is located at the address:

Computer Configuration\Policies\Administrative Templates\Printers.

This means that the checkboxes opposite Users can only point and print to the server (The insertion function can only be used on these servers) and through the dot with which the foreign domain names of the servers are indicated (FQDN). At the application: prints.test.ru. In the Security Promts field, the parameters "Then installing drivers for a new connection" and "Then updating drivers for a exsiting connection" are set to: Don't show warning or elevation promt ( Do not display advances or write to advance rights).

We will not indicate that the policy is also enabled: Package Point and Print - Approved servers, which is located there at the address: Computer Configuration\Policies\Administrative Templates\Printers. This policy is completely independent of Point and Print Restriction and is extended only to package drivers, which as a result helped to remove the problem that occurs when installing a universal driver in Kyocera.

In the Enter fully qualified server names field, you can set the name of the server for each other. Pressed zastosuvati. On the print server and client PCs, we launch the Primus update policy using gpupdate /force. Once installed, the printers may operate without power.

3) Print Management console. Adding printers to the pool (Print Pooling);

Print Pooling is a technology that allows you to combine a number of printers into one logical one, which can be useful in organizations with a large volume of each other and a large number of printers. For example, in a situation where there are 5 new printers and it is not clear which of them requires a signet, and which is the best, one logical printer installation in the system allows you to automatically identify the right printer in the pool, which ultimately saves time between decisions Send the task to a friend and actually with the signet itself.

In order to combine a number of printers into a pool, go to the Printers section of our print server and add a new printer to the system or select a new one. Then we go to the Ports tab and add a new TCP/IP port that represents the IP addresses of another printer in the current pool.

Select Standard TCP/IP Port and stamp New Port... Then enter the printer’s IP address, stamp Next and Finish. We add as many ports as we need in the pool.

Now we go to the current logical printer, to the Ports tab, which means the Enable print pooling checkbox, then further select the port 192.168.0.210 and press Apply;

In this way, we added two physical printers to the pool and took one logical printer out.

4) Print Management console. installing printers under group policy;

Why is it that in our organization there are 50-100 or more computers, and as it often happens, business owners themselves do not want / do not want to use or do not know which printers in the catalog they need to install? In this scenario, the printer installation tool will help us with the help of group policy. For example, if it is clear that the customer or group is responsible for installing a new printer, then the required printers can be automatically turned on later, without notice for the customer and without direct input from the system administrator. To do this, you need to log in to the other server under a domain account with Print Operators rights or more, then go to the Print Managment console, select the required printer and right-click to select the Deploy with Group Policy item. As a butt, let’s complete this operation for the “Operatori” printer. In the GPO name field, select the group policy object to which the automatic printer installation policy will be extended. I will select behind the creation the Operator object, which has its own connections to the Operators subsection, in the middle of which there are the user objects for which the printer is installed.

This checkbox indicates to whom the printer connection policy will be extended, to personal computers or computers. Embossed add, zastosuvati, OK.

The client computer is restarted and the “Operators” printer is successfully added to the system.

5) Transfer of configuration from one server to another;

If you replace a server with another or an emergency situation, you may need to quickly update the original configuration to another server. And to speed up the update time, you should already have a backup machine in stock from the installed service and then export the backup file in a special format.printerExport. This file contains a new copy of all installed printers, ports and drivers that allow a similar configuration to be run on another server. In order to extract such a file, you need to go to the root of the local server of the Print Managment utility, under our 'prints (local)' tab, right-click and select Export printers to a file... (Export printers to a file). Complete the instructions in the master and extract the backup file as output.

Within the framework of this article, the current (output) server has the following names: prints, new, final, where the configuration is transferred: prints-new, in this way the time frame for transferring data from one print server to another will be immediate:

1. On the backup (new) server, the role of the document service is elevated, since it was not added before.
2. On the old server, you can publish in Active Directory, uncheck the List in Directory checkbox for each installed printer, or you can see all printers at once and select with the right button: Remove from Directory;
3. It appears, as much as possible, that the old server in the domain is being renamed to prints-old. If this option is not available, for example, once the server is physically logged out, then we can delete the computer/server on the controller, for example, from the “Active Directory Users and Computers” snap-in in the Computers container. On the proposition, delete all contributions of the object (Confirm Subtree Deletion) apparently firmly.
4. On the new server, where the configuration is being transferred, we change the names to prints and add them to the domain.
5. Before exporting, the .printerExport file is updated on the new server. (Import printers from a file…). During the import process, you can immediately publish printers for direct access to the directory service (List in directory). After this we check the operation of the printers on the new server.

6) Troubleshooting problems in the service of each other;

Well, before there are any problems with the process of working at the service of each other, there is nothing special to write here, because everything comes down to just a few steps, according to the service level, cleaning up in %windir% System32 spool PRINTERS and the upcoming start of the service, which seems to be practical for every administrator and not only that. For the sake of completeness, I’ll give you the complete sequence of commands for my “green” friends:)

Launch the command line - cmd.exe;

We are doing our best to serve each other:

Net stop spooler

Clean your hand and look for *.SHD, *.SPL, *.TMP files in the middle of the directory with the command:

Del /q /f %windir%\System32\spool\PRINTERS\*.*

Let's start the friend service:

Net start spooler

Or a preventative restart of the service, without clearing the cherga:

Net stop spooler & net start spooler

You can create a batch file to run it in automatic mode. The file is saved, for example, under the name spool.cmd.

Setlocal net stop spooler del /q /f %windir%\System32\spool\PRINTERS\*.* net start spooler

You can restart the service using the additional gui interface, in the “services” equipment - services.msc, and clean the PRINTERS folder in Explorer, or in the console or in the swede batch file.

Current print servers can be divided into two types depending on the method of connection to the limit - dart and non-dart. However, do not forget that there are still printers that work through the LPT interface, and you should add one more parameter for adjustment - for the connection of the printer itself. At the moment, the function of print servers is supported by only a few routers, which allows the speed of a number of peripheral devices that need to be processed. Tim is no less, today we marvel at the reports in the butts, which can differentiate one independent device from another.

TP-Link TL-PS110U

This is the simplest representative of this class of edge structures. The print server has one USB connector for connecting one printer and one RJ-45 socket for connecting to a local network. The device is one of the largest of those currently available on the printer market and has a very simple setup interface that will be practical for any user. With the majority of current operating systems, you can easily connect the printer to the customer’s computer.

TP-Link TL-PS310U

Unlike its younger “brother,” this print server supports connections to up to four different devices using a special docking station. In this way, you can “share” not only a printer or MFC, but also a scanner, a webcam and various USB storage devices. So, as a young model, this print server has one USB connector and one RJ-45 connector. The device has a large number of modern printers, making it an excellent choice for use in the home or small office environment.

TP-Link TL-PS110P

This print server is a kind of anachronism, but it will be indispensable at these levels, where printers with LPT connections are still used. This device is also connected to shotguns, and has one connector for connecting to a local network for additional spinning bets. However, instead of a USB connector, the print server uses an LPT port and allows you to connect more printers via a parallel port. Like previous print servers, the device has a simple setup interface and is compatible with most current operating systems.

TP-Link TL-WPS510U

The main functionality of this print server is wireless connections. TP-Link TL-WPS510U connects to a local Wi-Fi network and ensures data transfer with speed up to 150 Mbps. It has all the necessary security functions, including data encryption modes 64/128-bit WEP and WPA, which will ensure the security of your work at any time. The device is compatible with most current printers, which require a USB cable to connect. It is worth mentioning that a variety of wireless print servers allow you to install a printer at any point of location, while wired print servers, as a rule, are located very close to routers, which will not happen forever handy.

Print server(English version) print server- server for others) - a device that allows groups of armed and non-dart users to use the printer.

Development of technology

Vlitku 1991 r. Hewlett-Packard first introduced JetDirect technology, which allows you to directly connect a printer to a local computing network. The first representative was the XIO (Extended Input/Output) interface card, which supports the Ethernet standard and various network protocols (TCP/IP, IPX/SPX, AppleTalk and DLC/LLC). Initially, the skin protocol required its own card; during further development, new types of roses were added. Born in 1992 a card with RJ45 and BNC connectors was presented, and in 1993. - first with parallel port (LPT). This made it possible to connect JetDirect cards almost to any printer, no matter what.

An increase in the spectrum of demand for other products and an expanded range of digital devices has led to the development of NetUSB technology, which is an emulator of the USB interface along the edge. The NetUSB technology was first introduced by TrendNet (2005 – 2007). Behind it was the company D-Link, which released its solution (SharePort). The situation with these technologies looks like this, no printer is connected directly to the computer. These technologies allow you to operate in a similar way other devices: MFP, scanner, flash cards, card reader, external hard drive, camera or video camera.

Today, the production of print servers is carried out by any company that maintains the least amount of ownership.

Zagalnye Vidomosti

A print server is a device that connects to a local network to which one or more printers are connected (the number of devices that are connected is determined by the type of device). There are two types of print servers: internal and external. External print servers generally work with any devices independent of the manufacturer's company, and internal ones - including printers from the print server manufacturer. However, regardless of the type of print server, it is “visible” to operating systems and requires the correct configuration of parameters for data transfer protocols that are used, including (TCP/IP, Internet Printing Protocol, Line Printer Daemon Protocol, NetWare, NetBIOS /NetBEUI).

Basically, print server models vary in type and number of ports that can be used to connect other devices, speed of operation along the edge, dimensions, as well as the range of edge protocols, which are suitable for the production sector. vati and, as a result, the ability of robots in a “rich operational” range (then local) network to which a PC with operating systems of different types is connected).

Yak Rule, in the Ketti-server, to the program of the program of oblivion, the Personal Parametry Parametry I will attach the rodshirebi-bungles of the di-diagnostics of the hollow, and the Viconuvati Piddogenny printer for the Kliyntsi comp'yutereri is permitted.

All models of print servers support configuration of parameters via a web interface, access to any local computer.

Robot principle

The print server is a computer or other device that operates other devices in one place. Due to the modification, to connect to the print server, the 10/100BASE-T Ethernet port is used, or it is connected via an additional wireless communication channel (IEEE 802.11 b/g/n). To connect the printer there is one or more LPT or USB ports. In order for the print server to function normally, it is necessary to make connections to the printer.

The operating principle of the print server is to collect requests from different computers along the route to the printer, and transfer information to the printer via the USB port. As a result, the printer is deprived of a formal connection to one device, although it really does not need to be limited.

Enter

If the connection of personal computers is still a common occurrence, anyone who wants a hard copy of the same document or any other document must have a printer, connecting directly to the computer. With the expansion of laser printers, it became necessary to give a new printer to the skin of the skin.

The first of the methods for connecting printers was the use of jumpers, which allow you to manually or automatically connect the printer to several computers. However, as a result, there is a need for long printer cables, as well as a coordinated effort to work on each other.

Server-based edge operating systems such as Novell NetWare have made it possible to share printers among a large number of users. Every hour, a separate security program sifts through the symbols that were supposed to go to the printer port and sends them to the file stored on the hard drive of the file server. The file server selects the work from the drawings and sends them to the printer, either to its parallel port or to the parallel port of one of the workstations. This solution allows you to significantly expand the number of workers who can send jobs to the printer, and eliminate the need to coordinate the workload, which is simply forced onto the printer when it is ready. In addition, the end of such work will be goodbye to administration. However, this method does not reduce waste. Attaching printers directly to the parallel ports of the server increases the impact on the new one and limits the distribution of printers: they are at fault only a few meters away from the server. In addition, a number of server ports are limited, which does not allow adding one or two more printers. Attaching a printer to one of the workstations lightens the burden of the server and ensures a tight connection to a new printer, which can now be installed practically in any handy place. However, when the workstation to which the printer is attached recognizes a significant third-party presence, the robot can properly comply. It is especially useful in peer-to-peer networks using Windows 95/98 operating systems.

Therefore, devices appeared that were called print servers and gave the printer new brightness. Think of a print server as a small box containing sockets for connecting to a computer, printer, and life-saving device. The number of ports for connecting printers can be changed from one to three. On some models there is also a serial port for connecting a printer via the RS-232 interface. The operating mode and the presence of voltage are indicated by LEDs. After connecting via a print server, the printer becomes an independent device that can be separated. You can get your money from anyone who is handy for the world.

Today's print servers usually provide operation on all common edge protocols, including IPX/SPX, TCP/IP, NetBIOS, NetBEUI, with all edge operating systems, such as Windows 95/98/NT, Novell NetWare, OS/2 and UNIX-like OS. The culprit is specialized print servers, designed for use only with office programs and oriented to work with Windows 95/98/NT/2000.

To set up correctly before installing the print server, set up the following first. For this purpose, the delivery package includes one or more utilities. Another widespread phenomenon has become the availability of a Web server in the print server warehouse, which allows you to carry out the necessary manipulations using a standard browser.

Also, unfortunately, print servers appeared that work in auto-negotiation mode 10/100 Mbit/s (which, in principle, is not feasible, since the speed of exchange of 10 Mbit/s exceeds the possibility printer) and parallel ports that work according to the ANSI 1284 standard. There are many parallel ports available, which allows for expansion in the future, since the difference in price for single-port models is approximately $20 . for an additional port, so the price of the entire print server can be 100 or more dollars.

Today's print servers are, as a rule, rich protocol devices that allow you to convert any printer into a web printer. As we call it, the printer is connected to a device called a print server, which is an edge printer itself, and not a print server. On the right is that a full-fledged print server operates not only by issuing jobs to each other, but by saving them on the hard drive (spooling) and organizing them in the order of retrieval. It is necessary to use the functions of saving the organization from the tested print servers, and it is not to blame for the care of these devices.

The main protocols that are used in current local networks are TCP/IP and NetBEUI, which are included in the networks that run under Windows NT/2000 and Windows 95/98. IPX/SPX is more common, which is similar to Novell NetWare. AppleTalk is, for all intents and purposes, an archaic rarity in Russia. Most print servers support all of the following protocols, although the trend to support IPX/SPX and AppleTalk is becoming increasingly noticeable.

There are two ways to organize work in conjunction with different hardware print servers: peer-to-peer and with a visible computer that spools and organizes work (and, in fact, with a print server).

The first method is rather labor-intensive, as it requires a new procedure for installing a border printer on your computer. However, it allows you to connect and configure a print server in an exact connection to your destination. In this case, the skin from client computers itself is responsible for organizing the transfer of data to the printer, and the data is transferred at least once.

Another method is when the print server is installed on one computer as a local printer, or otherwise as a printer on a remote computer. This method is much simpler for Vikonanna, but is more important both on the computer, before directly connecting the print server, and at the same time, since all data is transferred to each other: first - to the computer that connects to print server roles , and the other - if the work from the drawings is actually transferred to the printer.

Criteria for vigor

It is theoretically grounded and practically proven that when working with a 10 Mbit/s network, the print server cannot be a small place. “Plyashkova Neck” is most often found in a printer that is not capable of receiving and processing data at a speed of 10 Mbit/s (1.25 MB/s, which translates to approximately 312.5 pages per second per hour of text or 37, 5 sides per hvilina For other raster graphics, display at a separate rate of 600 dpi). In a small place you can register in a moderate OS. Therefore, productivity measurements were not carried out and the assessment was purely functional. This included installing a print server in a peer-to-peer network using the NetBIOS and TCP/IP protocols, as well as installing it on one computer as a print server using the same protocols. After installation, another Windows test site is run. Windows 2000 was installed on all computers, a domain was created and a DHCP server was running.

Results

Axis 5600+

This is a three-port Viconian print server in a plastic casing in a grey-black color. There is no wall mounting on the case, so the print server can only be placed on a horizontal surface, for example, on a table or on a table.

The front slanted station houses two LED indicators. The first one – Power – lights up when power is supplied to the edge adapter. This minute means that there is a problem with the print server or edge adapter. The other - Network - burns down the hour of data exchange along the line.

On the right side station there is a Test button and an RJ-45 socket for connecting to a local network. Press the button once until a test page is displayed on the printer, containing short information about the print server. Dvorazov's onslaught will ensure the conclusion of the report of the rich-storinka friend. On the left side station there is a nine-pin connector for connecting a printer behind the final RS-232 interface. The rear wall is completely occupied by two 25-pin DB-25 sockets for connecting printers via a parallel interface.

The Axis 5600+ print server is a universal device, designed to work under Windows 95/98/Me/2000/XP, UNIX, NetWare, OS/2 and Macintosh. For all these operating systems there are programs for installing and managing a print server.

On operating systems Windows 95/98/NT/2000, Windows 3.1/WfW, NetWare Pure IP, OS/2, which use the TCP/IP protocol, you can use the proprietary utilities AXIS Print System and AXIS ThinWizard. For configuration you can use Web Browser, FTP, telnet, SNMP, HP Web JetAdmin.

When working with Windows 95/98/NT/2000, Windows 3.1/WfW, OS/2 using the NetBIOS/NetBEUI protocol, you can configure and use the additional utilities AXIS NetPilot and AXIS IP JumpStarter.

It’s interesting that the print server was unable to perform diagnostics on the Samsung ML-1210 printer. And with the HP LaserJet 1100 printer, everything turned out wonderful.

CNet CNP410

This server is also intended for installation directly on the printer socket. When connected, the N-Way function is enabled and automatically determines the maximum transmission speed, and then automatically sets the port to work at that speed.

Glossary

ANSI 1284 - the standard, which was new in 1994, describes methods for transmitting data over a parallel interface and reaching the original Centronics port in much the same way as a Pentium processor up to 286. Below are the specifications for the LPT port. However, you will be deprived of the absurdity of outdated devices.

The following modes of intensity are supported:

Compatibility Mode- Standard Centronics;

Nibble Mode- 4 bits parallel to the lines, HP Bi-tronics;

Byte Mode- 8 bits along the data lines, which can be guessed as bidirectional;

EPP(Enhanced Parallel Port – extension of the parallel port) – is used mainly for communication not with printers, but with devices such as CD-ROM, streamer, MO-storage devices;

ECP(Extended Capability Port – port with extended capabilities) – mainly used for connecting new printers and scanners.

The standard also includes methods and protocols through which, as a result of negotiations, two devices select the most suitable mode.

IPX(Internetwork Packet Exchange) – a protocol used for delivering data without establishing a connection. It is divided on the basis of the IDP (Internetwork Datagram Protocol) protocol from the XNS (Xerox Network Service) set. Its main functions are data delivery and routing.

IPX/SPX- a nickname for a set of protocols developed by the Novell NetWare OS. Before the advent of IntraNetWare and NetWare 5, this set was “ready” and installed without difficulty. This is a compact protocol that does not require customization of routing, ideal for local networks.

NetBEUI(NetBIOS Extended User Interface) - IBM's expansion in 1985. This expansion stagnated at the Token Ring boundary. In one ring, up to 260 devices were allowed to be visible, and the rings could be connected to additional bridges.

NetBIOS(Network Basic Input/Output System) – a software interface developed in 1983 by Sytec, Inc. (nin Hughes LAN Systems) on agreement with IBM. It includes an API (Application Program Interface), which allows you to isolate additions from the edge middleware, and a number of edge proprietary protocols. In one measure, the presence of 72 and 80 devices was allowed (depending on physical implementation). Identification of devices may vary depending on the name, so you don’t have to enter 15 characters. Some parts of this protocol are not routed if the encapsulated version of it is implemented in the IPX and TCP/IP protocols.

P.J.L.(Printer Job Language) - in addition to the standard PCL (Printer Command Language) allows the printer to include additional functions, such as duplex communication via a parallel port. The printer can transmit and receive data about the status of indicators and settings on the remote control; Due to the presence of several ports, the printer can be configured offline, and data can reach the buffer, which means that it is in offline mode; Contextually-dependent mixing allows you to automatically recognize the type of work (PostScript and PCL).

SPX(Sequenced Packet Exchange) - a protocol of the transport layer, purposes for the delivery of data from established connections and guaranteed delivery. Based on the Xerox Sequenced Packet Protocol. The main function is guaranteed delivery of data. In relation to IPX it is approximately the same as TCP in relation to IP.

Today's printers, which are directly connected to the edge, have become traditional office equipment. The stinks will be ensured by a quick friend and simple installation regardless of the expansion, which is so important to the administrators of the boundary. However, in organizations with a local network of small and medium scale, the most extensive version of the integrated network is the lack of a personal printer, connections to one PC (Fig. 1). The main advantage of this option is economy. However, remember that with this method, the resources of the PC are consumed before the printer is accepted, and the productivity of the computer is significantly reduced. So, with the great commitments of the careful friend of the vikorist, the PC for direct reasons becomes even more important. Seeing one computer is too much for the average user, as is the addition of a special edge printer, which is often unreasonable from a financial point of view, especially since it is necessary not to outweigh the capabilities of another device. For most of these problems and requests, please help the so-called print servers or other servers.

Print servers are small edge-to-edge devices that can connect one or more printers (small 2). There are two types of stench: external and internal (Fig. 3). The remaining vikonans appear to pay and, as a rule, can only be vikorized with singing devices that are in harmony. The biggest problem with internal border boards is that they are required to support a specific printer. This means that if the printer was prepared before the advent of such devices, or if the printer is new and does not support the internal cards, the external device may become stuck in a moderate manner.

Small 2. Print server for two printers.

Small 3. External and new print servers.

In addition, the internal board serves only one printer. External servers simultaneously service a number of printers, and thus protect the additional ports. When one device runs a large number of printers, it also reduces the consumption of configured and necessary resources. For example, for each printer, only one IP address is sufficient, if printers with an internal board are able to see the surrounding address.

Often, internal fringe payments may be interchanged due to the number of supported fringe protocols and one-hour delays: it happens that the required protocol is not supported and two protocols cannot be processed simultaneously.

The external server will provide a clear view, more vikoristan of the edge printer. So, just like a connected computer with a printer connected to it, the external server is connected directly to each other, and the printer (or printers) is connected directly to the server. In this situation, there is no need to spend money on the purchase and maintenance of an extremely expensive PC - instead of this, an inexpensive, small-sized, simple-to-use device is used.

Advantages of external print servers

Print servers are highly recommended to be installed in medium and large areas, where remote installation of other devices is required. It is especially effective to use it in such situations if there are a lot of printers located on different surfaces and on different boxes, and it is necessary to give the administrator maximum control capabilities and - maximum skills for working with them.

Cost savings

For each computer or file server with a connected printer, you need to get a computer or server, but you have to travel a lot. Costs are growing rapidly, as there are a lot of printers that require extensive access, distributed throughout the office. It is much more expensive to connect the simplest computer to a smaller protocol server, and the other one is constantly supported by a bunch of printers. In addition, the server allows you to shorten the hour that is spent on maintaining the service (servicing a computer will require significantly more than an hour).

Rozvantazhennya of the main processor

Processing a task takes up a lot of CPU time on the computer to which the printer is connected. If the PC saves other work or uploads files to private access, it is necessary for you to save other work on your site. Productivity also depletes the productivity of the other person, since the computer immediately completes a number of tasks, which is essential for the processor.

The reason for the great emphasis on the processor lies in the so-called software input-output mechanism. The essence of this is that if the server forces the printer to send instructions to each other, the processor will experience processing overload. In this case, it does not matter what kind of computer is being used - an outdated XT or the latest Pentium 4-based machine. The capabilities of the server are growing rapidly, as it serves a number of printers.

The server, instead of program-by-character I/O, has direct access to DMA (Direct Memory Access) memory. And here the processor does not process entire data packets. In this way, the server not only destroys the computer or the file server, promoting the efficiency of completing other tasks, but also allows access to a more moderate approach.

More convenient placement

When connecting printers to a computer or file server, you do not have to select their location. And the fragments of the server, for example, should be refurbished in a safe, specially air-conditioned or close to the system administrator, they are often inaccessible to most clients who have to go on long-distance “walks” to take them to Documents were sent to another person. Merger servers, however, allow you to place printers in any network location where they are most needed. Although they are small in size, such devices can be connected directly to the printer or placed in places where no one cares.

Dodatkova obrobka zavdan

Often in a heterogeneous middleware, the work force, created in different operating systems or edges, extracts additional processing before sending it to the same printer. For example, in many UNIX-based systems, it is necessary to insert a “carriage reversal” at the end of the rows, otherwise the printer will render the text as a “crawler”. Another standard feature before the front processing is a separate cover for the skin, so that printers can find their documents at the printer's output tray. In many cases, the printer needs to be configured differently for different users.

This function is often provided on servers using additional virtual printer technology, thereby completely protecting the use of additional devices. With this technology, special virtual printers are configured directly on the other server. Customers send their assignments to a virtual printer, and the assignments undergo advanced processing without delay. For example, one virtual printer can be used to insert carriage rotation characters in jobs on computers running UNIX, another one can be used to convert the ASCII format into PostScript format for computer users whose additions do not support this format, and a third one can be used to to establish priorities for the management of employees, who needs to ensure the singing level of security. In addition, all virtual printers can be configured to use the same title page. The advantage of the server is that all virtual printers are located on one server and all clients are served by one physical printer.

Management capabilities

It is important for hedge administrators to know what the hedge expects. If the document is entrusted to the server, it automatically generates notifications about the number of printed pages, as well as notifications about printer problems, for example, about its inaccessibility, jammed paper or its absence. These notifications are sent to the most diligent administrator by email or registered in the system log.

In addition, other servers often support SNMP management, which makes it possible to perform the same functions as standard SNMP add-ons such as Hewlett-Packard's OpenView, Sun's SunNet Manager, or Castle Rock's SNMP.

Print server capabilities

Servers are currently released by companies such as Axis Communications (http://www.axis.com), Digi International (http://www.digi.com), D-Link Systems (http://www.dlink) .com), Hewlett-Packard (http://www.hp.com), Intel (http://www.intel.com), Lantronix (http://www.lantronix.com), Lexmark (http:/ /www.lexmark.com), Microplex Systems (http://www.microplex.com), NetGear (http://www.netgear.com) and others (Fig. 4). The dimensions of this device are slightly larger than that of a standard video cassette. There is also a connector for connecting a power supply, an RJ-45 Ethernet 10/100 Mbit/s socket and a number of printer ports (parallel and serial). All devices contain manufactured concentrators. All servers can simultaneously work with other text devices and PostScript printers. Most of the printers on the market are combined with these servers, or do not work with them. These are inexpensive devices, such as the HP DeskJet 700, 820 or 1000. To access most of the functions associated with image rosette, use Windows 95/98 and use only the same Yes, if you are connected directly to a PC with the same OS.

Small 4. Print server D-Link DP313.

In addition to the new web servers, all servers can be configured using the browser. New devices are required to support IPP (Internet Printing Protocol). Automatically assigned IP address and intuitively understandable printer names using DHCP and WINS/DNS make their installation and configuration easier. Each device can run test messages or display status messages that contain information about your IP address, active protocols, number of documents transferred to each other, types of printers connected to each other, and other types. osti. Some print servers are equipped with a special verification button; when pressed, a diagnostic data breakdown is displayed on the printer. In most cases, the server itself can determine the type of connected printer and the required network protocols. Automatic recognition of speed and data transfer midpoint eliminates the need to configure these parameters at the time of installation.

Make sure your skin print server package includes a CD-ROM with configurable and supporting utilities. The fragments of the new servers are based on an open architecture and can be upgraded using new firmware stored in flash memory. This allows you to adapt print servers (within a few hours) to continuous technical changes.

In order for edge servers and client PCs to communicate with the server, they must be properly configured by installing drivers for new edge printers. There are two main configuration methods: the first one transfers the creation of a virtual local printer port (on a PC or server) behind an additional software that serves as the server’s driver to each other, and the other one uses the new IPP protocol (as the client OS supports it). Each server on each other has special features, including creating an installation disk for a new printer that contains the driver for that printer, as well as information about the IP address of the other server and the password for accessing that printer. You can install the printer driver in another way - using the additional IPP protocol.

Greetings to your friend

The printer is suitable for any type of configuration. Other building servers will provide much greater speed than the standard parallel port of a computer, and in most cases supply data to a smaller, lower-quality printer. For example, other Microplex servers have parallel ports with a productivity of over 200 thousand. characters per second. A standard parallel computer port will provide transmission of approximately 30 thousand. characters per second.

Here it should be emphasized once again that print servers support a wide range of household devices - from new laser printers to the oldest dot-matrix printers. In addition, we support all your languages, such as PostScript, PCL, HP-GL and others. The server is absolutely not sure what type of data to go through. It simply shrewdly transfers data to connect printers and printers. One caveat - if you need special data processing, for example, converting ASCII into PostScript. In this case, the server looks at each other's data in order to determine whether it needs to be processed.

Apparently, in order to assess productivity, it is necessary for one to know the “knowledge” of the process. So, during the hour of preparing a task for another, the text processor spends an hour converting the document from official internal format to printer format, such as PCL or PostScript. The transformation process depends on the size of the document and the productivity of the text processor during this operation; You can be quick or take quite a few hours. The hour of transformation also depends on PC productivity. The hour it takes to transfer a task from a text processor to another is called the swap hour. This is determined by such factors as the productivity of the application program when moving data to the printer port (or to another), as well as the productivity of the network when transferring data to another and placing it on the printer. The hour when the wife checks the cards for each other is called the hour of recuperation. It depends on a number of factors, including the number of tasks that stand in front of it, its size, the speed of the server and the method of its recovery. The server periodically checks the card with each other, as soon as it has started, in order to determine whether it is given to the other. If there is such a drawer, and the printer is quickly accessible and ready for reception, the server will then move the work from the drawer to the printer. This process is called pumping or document changes, and the hour required to move all the work to the printer is called the pumping hour. The factors that regulate the time at which pumping is released are the speed with which the server can send data directly to the printer, and the speed with which the data can be sent directly to the printer. Another key factor is the speed with which the printer receives data.

As practice shows, the very hour of pumping off often delivers the maximum influx to the flow system. In a well-organized border system, the hour of recuperation counts for little, since the left hand often appears united across the board. In such a situation, as soon as the text processor finishes pumping, there is one thing on the right that you lose - a return to the other, at the end of the hour when the pumping is removed, so that it remains with the server.

The servers serve each other on equal platforms using the FIFO principle: First In - First Out, so there is no advantage for other computers or a measure. The skin I/O port is known to have moisture in it, as it is formed independently from other ports. Thus, a print server with several I/O ports (two parallel and two sequential) can support any number of functions that serve its printer. Porti encourage each other at the same time without risk of mixing and wasting the order.

At any time, the server saves more than a few kilobytes of data on each I/O port, and other data is saved on the storage device. Today there are simply no servers on the market that can be placed in the buffer file of the task, so the computer-device always takes part in the buffering of the task. Most often this operation ends quickly.

Dividing access

If the server is not equipped with security features, then regardless of how many security mechanisms are included in the third-party operating system, the network administrator removes the open system, but there is no way to prevent access to the client. c, as they do not have sufficient rights. The ability to separate access to the printer has significant potential benefits. Zokrema, unauthorized use of another device will lead to increased costs for support and materials. As the printer is another unauthorized product, it is not available to business projects, which may be subject to harsh terms. The effects of poor printer control can be more severe if servers serve other printers, checks, payment slips, and other accounting documents. In many cases, demarcation of access allows you to avoid serious negative consequences that could lead to unauthorized access in settings that handle confidential documents.

In many cases, administrators have to organize a centralized staff for each other. Clients transfer the work to a centralized file on a file server, which then sends the work to the server to another, and that one, in turn, sends the work to the printer. Therefore, such disciplines of system administrators can centrally manage all the assigned tasks of the client. This allows you to take advantage of the capabilities of edge OSs, such as automatically installing a printer driver when connected to one, while saving productivity and freedom to move servers to each other.

In certain situations, directing the task to a centralized staff is either impossible or ineffective. As an example, you can establish a remote office equipped with more work stations and connections with the headquarters with a full communication channel. It is often impossible to create a centralized solution either through the use of file servers or for other reasons. In such situations, it is reasonable to place work stations directly on each other’s servers. Each other's servers support both advanced access and direct access.

If the protection of the edge OS is created to limit access to the other file server, then with the help of any computer connected to the edge, you can send the task directly to the other server, without controlling the edge OS. The smartest solution is to equip the server itself with protection functions.

One of the most pressing problems of unauthorized access is the use of Intel's password protection technology. This technology complements the security features found in most edge operating systems. The security check is carried out immediately if the user tries to directly touch the edge printer, bypassing the safety features of the edge OS. For example, on other Intel NetportExpress 10 and 10/100 servers, administrators can set a password for access to any connected printer. At the same time, for example, if users force tasks to be sent to each other on a Windows NT server, the administrator can adjust the settings of the NT server so that the task is transferred to the server to the other user using a designated password. A file server is a single computer that needs to know its password. The administrator maintains access to all other users for additional security features of the third-party operating system. It should be noted that in the situation where work stations are directly connected to the printer, there is no centralized task force and the edge OS does not control access to the other server. Anyone can quickly use a printer. This technology serves as an interchange, replacing the security features of the edge OS. Other documents can be processed on the same printer from their workstations unless you know the password. If the work station enters the wrong password, then the assignment to the other device is simply not saved, as if the printer was fired without connections until the end. So, if the administrator has three printers in his order, connected to the same server, then any of them (or all) can be secured with a unique password. For example, if both monochrome laser and color inkjet printers are connected to the server, then access to the laser printer can be allowed to everyone, and access to the color inkjet printer can be protected by a password. Printer passwords can be accessed on UNIX, Linux, Windows NT, Novell and AS/400.

Today, most new devices can be limited to adjacent printer ports. Such an exchange may be necessary, for example, when printers hold a special paper (various types of paper, forms, etc.) or when it is necessary to secure each other through a file server (which works under Linux, NetWare or Windows NT). Since the server is configured to allow access only to the file server, users cannot bypass the other server and communicate directly with the server. Each other’s servers can also share access to their Web interfaces using an additional password.

Protocol support

In heterogeneous networks, administrators have to maintain the integrity of various services and protocols. Print servers allow multiple printers to create edges on the same printer, using different edge protocols. In this manner, this is a miraculous way to change the quality of the work place. Customers can use the same printer, as they work on different platforms. Today's servers are expected to support TCP/IP, IPX, DLC/LCC, AppleTalk/EtherTalk, NetBIOS/NetBEUI, LAT protocols, although they can be used in a variety of environments. Depending on the protocols, some of them include LPD, RSHD, FTPD, direct connection, PSERVER, RPRINTER, LPD, dispatcher, etc.

With the constant growth of computer systems, the control of the seal is becoming increasingly complex. The problem is with the print server itself. And the more “reasonable” they are, the more functions the brothers have on themselves, the easier it will become for the administrator to maintain boundaries, and the backers will be able to work much more effectively. Over the past few years, fundamental changes have taken place in the border force, and there is no end in sight to the upcoming process of change. Companies want to find solutions for a remote scale of enterprise, and third-party administrators are focused on tools that would simplify management and ensure greater centralization of their processes.
