One of the purposes of a computer is to create an overwritten version of a document or a so-called hard copy. The printer itself is an indispensable accessory for a computer. However, this does not mean that a printer will be added to your computer.

With a wider range of local networks, one printer can serve many customers.

Scanners are most often used by artistic departments of companies, so they can be found in use at home.

There are currently a large number of printers on the market, with different characteristics. The criteria for choosing one or another printer will also be described. We will look at the basics of hand technology, types of printers and their functional capabilities.

Technologies at hand

Today there are three main technologies in use.

Laserna. A laser printer operates in a straightforward manner: an electrostatic image of the side is created on a photosensitive drum using a laser exchanger. When placed on the drum, specially fermented powder, called toner, “sticks” only to the same area as the letters or images on the page. The drum rotates and presses against the paper's arch, transferring the toner to the new one. Once the toner is fixed on the paper, the image will come out ready. A similar technology is used in copy machines.

LED printers produced by Okidata and Lexmark operate similarly. Instead of a laser, they use an array of light-emitting diodes.

Strumenevo-Chornilna. In inkjet printers, ionized droplets of ink are dispersed through the nozzles onto the paper. Discoloration occurs in these places, where it is necessary to form letters and images.

Matrix of points. Dot matrix printers have a group of round heads that run along the arch of the paper through a barvist stitch. These heads are made of a straight mesh, called a matrix. When the singing heads are pressed against the matrix, various symbols and images are formed.

Laser printers provide the most power, followed by inkjet printers, and then matrix printers. The price of laser printers is gradually decreasing, so they are becoming available to a wide range of buyers. Nowadays, inkjet and matrix printers are becoming more specialized: inkjet printers are used as the main devices for color printing, as well as for the market, and matrix printers are used mainly for high-end and inexpensive printers (for example, in banks or stores for receipts ).

Today it is practical, in specialized areas, to use laser and inkjet printers. This section covers the basics of printer technology implemented in different types of printers.

Expansion

The term separate design is used to describe the contrast and brightness of the over-armed image. In all of the technologies considered, the image is created along the same path as a point on the paper. The separateness of the printer, and therefore the capacity of the hand, depends on the size and number of these dots. When looking at the side of the low-separated section on a dot matrix printer, with an unbroken eye, you can draw a line from the dots that form the characters. This is due to the fact that the points become large and reach a new size. And when looking at the page, which is designed with a high section on a laser printer, the symbols have a “serious” appearance, the dots are much smaller and appear in different sizes.

Allow the printer to change dots per inch; In other words, there are a number of small dots that can stretch the printer along a line of one inch. For most printers, the separate part is defined by two directions - vertical and horizontal. Thus, under separate conditions, 300 dip is equal to 300x300 pixels per square inch. A printer with a separate 300 dip unit can print 90 thousand. pixels per square inch of paper. There are printers that have separate outputs for two different directions (for example, 600x 1200 dip). This printer can print 720 thousand. pixels per square inch.

It is important to understand the difference between the printer and monitor permissions. The term separation in PC monitors refers to the number of pixels, for example 640x480 or 800x600. If you change this to a “printer” standard, you will get 50-80 dip. Based on the actual size of the image (even the width) on the monitor screen and based on the number of pixels, you can calculate the size of the monitor in dots per inch.

Well, it’s not possible to understand the WYSISWYNG (What YouSee IsWhat You Get) technology completely. The printer with the lowest separate part produces more dots, which are displayed on the monitor.

The three main types of printers use different methods of creating images on paper and different materials: powder toner, ink or fabric stitch. The following sections will tell you how images are created on paper on skin-type printers.

Laser printers

The process of printing a document on a laser printer consists of the following stages: - connection; processing of tributes; format; roseterization; laser scanning; toner refill; Toner fixation.

While different printers complete their actions in different ways, most printers complete the same sequence of actions. For example, inexpensive printer models rely heavily on computer processes, while more expensive and sophisticated models rely mostly on expensive hardware and software.

LED printers

These printers were developed by Okidata and entered the market as an alternative to laser printers. In both types of printers, the same principles are used for creating images on paper, with the exception of a device that is used to neutralize the light-sensitive drum. Laser printers use a laser, while light-emitting diodes (as the name suggests) use an array of light-emitting diodes.

In terms of productivity and brightness, LED printers do not compromise on similar models of laser printers. They are sometimes called “laserless laser printers” and are manufactured by Okidata and Lexmark.

Strumenev printers

The processes for interpreting data using jet and laser methods are basically similar. The difference lies also in the fact that inkjet printers have less memory and a smaller computing system. This very dignity places them in the lower class of rank. Changes to the memory installed in the printer can lead to the fact that in such printers buffers are used instead of buffers for entire pages.

The main difference between inkjet and laser printers is related to the process of forming the image on the paper. The technology used in inkjet printers is much simpler than that of laser printers; It requires less expensive materials. Instead of the folding process in which toner is placed on a drum and then transferred to a paper, inkjet printers rarely spray the ink directly onto the paper - the same place where a dot mass is formed in a laser printer. Simplifying the process is practically ideal due to the use of inkjet technology in portable printers.

Currently, there are two main types of steam flow: thermal and electrical. These terms describe the technology of spraying ink from a cartridge through nozzles. The cartridge is folded into a reservoir with thin ink and small (about one micron) openings, like ink placed on a paper. The number of openings is stored in a separate printer and can range from 21 to 256 (or more) per color. Color printers have several (or more) reservoirs with different color inks (black, magenta, yellow and black). By mixing these four colors, you can create any color. Some printer models have one cartridge with three reservoirs of color ink (black, magenta and yellow).

Portable printers

Portable printers use two different technologies for creating images on paper. The Citizen models have a pure thermal technology with a special farbing line and other heads that have 60 degrees. The main disadvantage of these printers is the limited resource of the stitching line: 30 black and white pages or 5 color ones, as well as low output - maximum 360 dpi. Portable printers from Canon and Brother are miniature copies of basic desktop inkjet printers and provide 720 dpi and a cartridge resource of several hundred pages.

Dot matrix printers

Unfortunately, dot matrix printers have always been the most popular due to their small size, low output and high reliability. However, after the decline in prices for laser printers and the emergence of inkjet printers, the markets for dot matrix printers began to change catastrophically. Regardless of the fact that they still manage their tasks miraculously, the robots must be “noisy”, operate with low viscosity and often replace the papier.

Dot matrix printers, like laser and inkjet printers, do not form the side of the document. In a dot matrix printer, the paper is placed on a vertical tray and moves in a row behind additional rollers. The other head moves horizontally along a special straight line and places the matrix from metal heads (most often there are 9 or 24 heads), which creates images on the paper. Between the heads and paper a barn stitch is sewn, like on a Drukarsky car. The dots (through the stitching) create a number of small dots on the paper, thus creating the image. Sometimes it is impossible to achieve high resolution for graphic images on dot matrix printers, which is why such printers are especially suitable for text documents.

On almost all dot matrix printers, you can print both paper frames and paper rolls within an hour.

In one place, dot-matrix printers have not yet created positions - not just banks and the sphere of trade.

Colorful druk

A color printer becomes an invisible attribute of a professional designer, artist or constructor. The simplification of inkjet technology has led to the fact that almost all printers began to produce inexpensive models of color printers, aimed mainly at the home and office computer market.

There are a number of different types of color printers, most of which are clearly adapted to monochrome technology. As a rule, color printers have a number of colors (depending on the number). Color inkjet printers have larger and larger reservoirs of color ink, while laser printers have more color toner. As with a color offset printer, you can create almost any color on a color printer by mixing the same proportions of four main colors - black, purple, yellow and black. This color model is also called the SMYK color model. Some inexpensive printer models come in three colors (without black). The black color is a combination of the maximum proportion of three colors. However, rejection as a result of color varies from what can be recovered from vicor and black farb.

Most color printers cannot simply mix colors, like an artist mixes farbies. This printer has different colors. For example, the inkjet printer is aligned with a point so that it does not overlap, at which point the skin is aligned with a solid color. The number of dots of one color in a view indicates the resulting color. The process of creating a song color is similar to the creation of an image on the monitor screen: to form the required color, three dots are drawn around it - red, green and blue pixels.

The availability of several color printers is not sufficient to produce a clear image. Over the course of an hour on such a printer, you can increase the number of dots. The cumulative effect (around the image points merge into a single picture) is revealed only when looking at the over-armed image at a clearly high level in front of the eyes: near the marked edges of the point.

When choosing colors, you will need a folding device to connect your printer and computer.

Regardless of the emphasis on color in the main language descriptions of pages, many printer manufacturers use power technologies (producing power drivers).

Currently, many programs have been created that can change color options. A good test for any printer is another photo. For example, for other diagrams from electronic programs, a table can be used almost any color, which cannot be said about creating photographs with natural colors. Some printers have six colors instead of four. If you want to remove the color of another illustrated multi-color magazine, an inkjet printer will be helpless. Sometimes other methods are different.

When changing color and monochrome hands, two important parameters come into play: hand fluidity and varity. For color printers, less fluidity will result in greater luminosity. This hardening can be applied to most inkjet printers. Therefore, in the future, separate color and monochrome prints from each other on an inkjet printer. So, for example, for another single-sided sheet, there will be no need to peel until the multi-colored material for presentation is prepared. The cost of color printers ranges from hundreds to thousands of dollars. However, there is another aspect of the friendliness: the friendliness of waste materials. With monochrome printing, one cartridge with ink or toner is enough for thousands of pages. However, the capacity of the cartridge is quite low.

Otherwise, deal with the colorful one. Most often, the color image is richer than monochrome. Sometimes the printer requires special, expensive types of paper. In addition, it is more expensive to purchase color cartridges with ink or toner. The value of the other side also depends on the number of different colors, for example, other photographs will be much more expensive than other pictures.

Now let's move on to a look at the main technologies of the color brush.

Printers with “curable” ink

There are “solid” jet printers, in which solid jets are used instead of rare ink. Such models are manufactured by Tektronix (a subsidiary of Herox). During the process, the haircut is melted and the mixture is transferred to the drum, and from there to the paper. With such printers, images are created the same way as with monochrome laser printers. The main advantage of “solid” inkjet printers versus color laser printers is the availability of less than one drum before the image is created. All image colors are created on one reel.

In this way, the softness of the hand will increase fourfold, and in addition, the strength of the hand will improve.

In the “hard-jet” process, the paper is not resistant to heating and pouring out the displaced moisture, so more inexpensive varieties of paper can be used. In addition, servicing such printers is much simpler.

Color sublimation losses

Color sublimation (or thermal color transfer) is a technology that combines a line with a wide range of fabrics and printers that heat up almost to a gas-like state. Before applying it to the papier, mix it to match the required color. These types of printers can print 256 colors of skin; Thus, the color palette reaches 16.7 million colors. As a result, this type of printer can be used to remove the color by hand.

Regardless of the amazing power of the hand, sublimation printers are expensive and require a special type of paper. In addition, do not forget about the cartridge quality! Color sublimation printers are comparable to thermal wax printers, although they have different color-drying technologies. Several printer manufacturers release models that support both technologies. This allows you to use thermal technology with applied wax (which is cheaper) for everyday use, and color sublimation technology for residual or other types of high-quality material.

Thermal printers with wax applied

These printers use wax-based ink, similar to solid ink. It must be melted before applying to papier. This process can be carried out much more easily, without sublimation, and it does not require special types of paper. Printers of this type are distinguished from other inkjet printers with greater efficiency.

Several portable printer models from different companies use different types of wax-based ink melting processes. They have a primary head, like dot-matrix printers, and a “farbuya” stitch (a mark for the black and residual edge).

Select printer type

There are thousands of printer models on the market, so choosing the model that suits your needs can take a lot of time. The price depends on the criteria by which you can select a printer.

The speed of both laser and inkjet printers varies in pages per hour, and in dot matrix printers – in characters per second. Increasing the fluidity of the hand and separate parts results in increased printer performance. For a home printer, hand speed is not of particular importance, but for an office this parameter becomes even more relevant, especially if the printer uses a number of printers. Another important parameter that is closely related to this is the printing cycle - the number of pages that the printer loads in a given period of time (mostly in a month).

The basic rule is: a decrease in the speed of the printer’s hand is caused by a change in the cycle.

There is another important factor in evaluating a printer – the type of paper used. Under this we mean special grades of paper for printing on inkjet or other types of printers, as well as the size of the paper, as well as its thickness. Almost all printers work with standard letter paper sizes in the USA and in Europe; In addition to these sizes, a number of other paper formats are supported. It is also necessary to understand how the printer works with different paper formats. A number of printers are equipped with a number of trays for paper paper, and trays from them can be customized for several types. When choosing an office printer, consider the number of paper trays. When purchasing a printer, please inquire about how you can purchase large grades of paper and envelopes at any time. The paper on a thick paper will fold correctly because the printer uses a special tray, and the paper will not bend over time. The ability to operate on inode envelopes is implemented as an additional module.

The quality of the materials used is the most important parameter when choosing a printer. The paper, color specifications (toner cartridge, ink cartridge or ink cartridge) and the thickness associated with the printer are used before expiring materials. For skin type printers, a special type of paper is required. Naturally, this papier is most precious. In laser printers, you can select a number of grades of paper, while for an inkjet printer (especially color printers) a different grade is required. The choice of paper depends on the type of other documents: for internal use, you can use cheaper types of paper, and for other types you will need to choose a better paper. Having decided on the color, you need to pay for the “price per sheet” by dividing the cartridge’s output into the number of paper papers you choose to use for this cartridge. As well as the fluidity of the hand, this parameter should be stored in the filling of the arch. Printing graphic images over and over again consumes more toner or ink. For laser printers, the price of toner depends on the model of the printed cartridge. In some printers, the toner cartridge contains a photosensitive drum and a toner dispenser unit, which promotes its output. Do not use laser or inkjet printer cartridges. Try to find companies that renew replacement cartridges. Renewal and refill cartridges (you can also clean the photosensitive drum) can be cleaned several times, thereby protecting the cost.

In addition to the quality of the materials, when choosing a printer, it is necessary to pay attention to the ease of use and normal operating modes. The newest printer models support an expanded power supply system and switch to a low-energy mode when there is extreme inactivity. Don’t forget that in addition to saving waste, you are also saving money.

The first time you get a printer, you need to formulate all the possibilities that can be confirmed. At home, you can completely get by with a basic inkjet printer using the capabilities of a color printer. If you need high document density, use laser printers. Well, if you constantly move with a laptop computer, you need a portable printer.

2. Table processors: document structure (box, sheet, book, work area), book attributes, types of boxes and methods of specifying them

Electronic tables – e Spreadsheets provide comprehensive capabilities for storing and processing different types of data. The most popular spreadsheet processors are Microsoft Excel (for Windows), Lotus 1-2-3 and Quattro Pro (for DOS and Windows).

The Excel spreadsheet processor also supports the advanced functionalities of text processors, such as macro editing, prompt diagrams, autocorrect and spell checking, style correction, templates, data auto-formatting, In addition to data from other programs, the detection of a faulty pre-production system, other settings and other service systems Possibility.

The Excel spreadsheet processor is completely unique in creating a table in the form of different formats, sorting, filtering, statistical analysis of arrays, and the basis of their diagrams.

We will describe the main key concepts that you learn every hour of working with the Excel spreadsheet processor.

The workbook is the main Excel document. It is saved in a file with additional names and xls extensions. When opened or opened, the workbook will be placed in a nearby window. Leather book for the industrial area to take revenge on 16 working arches.

Sheets are used for creating and saving tables, diagrams and macros. Arkush consists of 256 rows and 16,384 rows.

The middle is the smallest structural unit for placing data in the middle of the worksheet. You can change the appearance of text, numeric values, formulas or formatting parameters. When you enter data, Excel automatically recognizes the type of data and indicates what operations can be performed on it. Instead, the middle ones are divided into weekends (to pour in) and long-term ones. The remaining entries contain formulas that may be sent to other parts of the table. Also, the values ​​of stale middles are calculated instead of other (such as added) middles in the table. The middle, vibrating beyond the help of the indicator, is called an active or precise middle.

Addresses in the middle of the assignments and destinations in the middle in the table. There are two ways to write the address of the middle:

1. The letter contains the row number of the table, which can be preceded by a $ sign, which indicates absolute addressing. This method of painting is called A1 style.

2. Indicate the row number and column number that appears after the letter R and C. Numbers of rows and columns can be placed near the square arms, which indicates specific addressing.

A formula is a mathematical notation that calculates what is calculated over the data in the table. The formula begins with a symbol or a mathematical operator and is recorded in the table. The result of the formula is the calculation of the value. This value is automatically recorded in the mailbox, where the formula is available.

A function is a mathematical notation that indicates a variety of computational operations. The function is formed by replacing one or several arguments placed on the round arm.

The middle indicator is a frame, behind which the active middle of the table is visible. The user moves behind the mouse or presses the cursor key.

A list is a specially designed table that can be used to work from a database. In such a table, each column is a field, and each row is a record in the database file.

Excel functions are used for calculating standard calculations in workbooks. The values ​​that are used to calculate functions are called arguments. The values ​​that are rotated by functions as evidence are called results. In addition to using the functions you can use, you can also use calculation functions that can be created using additional functions in Excel.

To use the function, you need to enter it as part of the formula in the worksheet. The sequence of symbols that appear in a formula is called function syntax. All functions follow the same basic syntax rules. If you break the rules of syntax, Excel will inform you about the errors in the formula.

Since the function appears on the beginning of the formula, it must convey a sign of equality, as in any other formula.

Function arguments are written in round circles next to the function name and are supported by one type of symbol with a dot followed by " ; “. The handles allow Excel to indicate where a list of arguments begins and ends. In the middle of the arms there are arguments. Keep in mind that when recording a function, it is important to open and close the arms, so you should not insert spaces between the name of the function and the arms.

As arguments, you can use numbers, text, logical values, arrays, meanings of pardons or messages. Arguments can be either constants or formulas. In its own way, these formulas can replace other functions. Functions that are arguments to another function are called nested functions. In Excel formulas, you can select up to seven levels of nested functions.

The input parameters that are specified are only valid for the given value argument. All functions can take unnecessarily complex arguments, which can be carried out every day during the calculation of the function's value.

For clarity, the functions in Excel are divided into categories: database and list management functions, date and time functions, DDE/External functions, engineering functions, financial information, I will look at these logical functions and send them. In addition, the following categories of functions are present: statistical, textual and mathematical.

For further help text functions It is possible to process the text: select symbols, find the necessary ones, write symbols in a strict place in the text, and much more.

For further help date and time function You can determine practically any task related to the date or time (for example, calculate the age, calculate the length of work, calculate the number of working days at any time).

Logical functions help to create complex formulas, which are necessary for the understanding of these and other minds to create different types of data processing.

Excel is widely represented mathematical functions. For example, you can perform various operations with matrices: multiply, find, transpose.

For further help statistical functions Statistical modeling can be carried out. In addition, it is possible to analyze elements of factor and regression analysis.

In Excel, you can perform advanced optimization and Fourier analysis. Zokrem, Excel implementations of the algorithm of a quick transformation of Four'e, with the help of which you can use the amplitude and phase spectrum.

Excel has over 400 new functions. Therefore, you can easily enter the formula, the name of the function and the values ​​of the input parameters from the keyboard. Excel has a special feature for working with functions Master of functions
. When working in this way, you are first prompted to select the required function from the list of categories, and then in the dialog box you are prompted to enter the input values.

Good afternoon.

I don’t think I’ll show America off if I said that the printer is a very good thing. Moreover, not only for students (those who are simply necessary for the development of coursework, certificates, diplomas, etc.), but also for other clerks.

Different types of printers are available for sale at a time, the price of which can vary dozens of times. Singingly, the food supply for the printer is even richer. In this short article, I will look at the most popular options for printers that I should install (the information will be useful for those who are choosing a new printer for the home). And so...

The article omits some technical terms and points in order to make it clear and readable for a wide range of journalists. The most important nutrition for kistuvachev, which causes the skin to stick when searching for the printer, has been removed.

1) Types of printers (inkjet, laser, matrix)

This drive needs the most power. It’s true that the choice of food supply should not be “types of printers”, but “which printer is better: jet or laser?” (for example).

In my opinion, it’s easiest to show the pros and cons of a skin-type printer by looking at a sign: come out right away.

Printer type	Pros	Minuses
Strumeneviy (most models in color)	1) The cheapest type of printer. More available at the price of all beliefs of the population.	1) The ink often dries out if you haven’t touched it for a long time. For some printer models, this may require replacing the cartridge; for others, it may require replacing the printer head (for some, the repair cost will be equal to the purchase of a new printer). So, it’s just a pleasure - print on an inkjet printer if you want 1-2 sides per week.
	2) Refilling the cartridge is extremely simple - once installed correctly, you can refill the cartridge yourself using an additional syringe.	2) The ink will quickly run out (the cartridge for the ink is, as a rule, small in size, about 200-300 A4 cartridges). The original cartridge from the printer is usually expensive. Therefore, the best option is to give such a cartridge for refilling (or refill it yourself). However, after refueling, often the text becomes not so clear: there may be smudges, tsatki, dilyankas, symbols and text may have been badly written.
	3) Possibility of installing continuous ink supply (CISS). In this type, a bottle with ink is placed on the side (or back) of the printer and the tube from it connects directly to the other head. As a result, you will be one of the cheapest! (Respect! Earning money is not possible on all printer models!)	3) Vibration during operation. On the right is that the printer constantly moves the other head left and right - through this vibration is generated. A lot of koristuvachs are fighting to the limit.
	4) Possibility of taking two photographs on a special paper. The color will be richer than on a color laser printer.	4) Inkjet printers are more efficient than laser printers. For a fee, you will tear up ~5-10 pages (when printing printer parts, there is actually less flexibility in the future!).
		5) The leaves are split until they “spread” (so that, for example, drops of water fall on them from bare hands). The text on the arkush will spread and spread what is written, which will be problematic.
Laser (black and white)	1) One refill of the cartridge produces 1000-2000 cartridges (on average for the most popular printer models).	1) The quality of the printer and the bottom of the inkjet.
	2) As a rule, the lower stringer operates with less noise and vibration.	2) Cartridge refilling is expensive. A new cartridge on all models is like a new printer!
	3) The variety of a leaf in the middle of the pack is cheaper than the bottom of the sheet (without adjusting the CISS).	3) Inability to handle color documents.
	4) You don’t have to worry about the “drying” of the toner* (in laser printers it’s not the substance that’s used as a jet printer, but the powder (called toner)).
	5) Shvidka shvidkist hand (2 dozen sides with text per khvilina - completely within the power).
Laser (color)	1) Color has a high liquidity.	1) A very expensive device (although the quality of a color laser printer is still becoming available to a wide range of people).
		2) Regardless of color’s strength, it’s not suitable for photography. Brush will be at a premium on an inkjet printer. And the axis of the documents is the same!
Matrix		1) This type of printer has long been outdated* (for home use). Nina is victorious, say, especially in “university” factories (under the hour of work with any kind of information in banks and others.).

My highlights:

1. If you are buying a printer for distributing photos, it is better to choose a basic inkjet (probably the model on which you can install a continuous supply of ink - this is important for those who will handle a lot of photographs). So the streamer itself will suit us in addition to other small documents: abstracts, evidence, etc.
2. A laser printer is basically a universal one. Send it to all koristuvachs, besides those who are planning other brightly colored pictures. The color laser printer for the photo tray (as of today) is given over to the inkjet printer. The price of the printer and the cartridge (including refills) is more expensive, but in general, if you get a new solution, the cost will be cheaper than on an inkjet printer.
3. Purchasing a color laser printer for the home, in my opinion, is not entirely justified (we accept that the price for them will not drop…).

An important moment. Regardless of what type of printer you have chosen, I would also check with the same store on one detail: how much does a new cartridge cost for this printer and how much does it cost to refill (refill capacity). But the joy of the purchase may disappear after the farb ends - many buyers are very upset when they find out that several cartridges for the printer are assembled in the same way as the printer itself!

2) How to connect the printer. Connection interfaces

It is important that the largest number of printers that can be sold support the USB standard. As a rule, there are no problems with connections, except for some subtle ones.

I don’t know why printers often don’t include a cable for connecting it to a computer. Sellers ask you to guess about it, but never again. Lots of cashiers (who are the first to stick with this) have to run to the store 2 times: once for the printer, the other for the connection cable. Be sure to check the complete set when purchasing!

The LPT interface is now becoming more common (previously a standard (even popular interface)). Before speaking, most PCs are still equipped with a digital port for connecting such printers. For a home in this hour of jokes, such a printer is a big no-no!

Wi-Fi and Bluetooth

Printers in the high-end price category are often equipped with Wi-Fi and Bluetooth support. And I have to tell you - the river is very handy! You know, you walk around the apartment with your laptop, you work on the evidence - then you press the button and send the document to the printer and then release the documents. Zagalom, tsya dod. The option in the printer will allow you to have a quick trip to the apartment (however, the document is first transferred to the printer - but in general, the difference is not so significant, since you use text information).

3) MFP - why choose a richly functional device?

The rest of the time in the market, we will spend some time looking for MFPs: devices that are connected to a printer and a scanner (+ fax, and another phone). These devices are very handy for photocopies - just put a sheet of paper and press one button - the copy is ready. Otherwise, I especially don’t care about great advantages (except for the printer and scanner - you can immediately get another one and remove it if you need to scan).

Before that, no matter how normal a building camera is, it will work just as wonderfully as photographs of books, magazines, etc. - it is practical to replace the scanner.

HP MFP: scanner and printer complete with automatic sheet feeder

MFP advantages:

Rich in functionality;

Cheaper, lower than okremo;

Shvidka photocopy;

As a rule, there is an automatic feed: find out how you can forgive the problem if you are copying 100 arkush. With automatic feed: put the leaves in the tray, press the button and go drink tea. Without it, the leather arch would have to be turned over and placed on the scanner manually.

Disadvantages of the MFP:

Gromizdke (short of a basic printer);

If the MFP breaks down, you will spend both the printer and the scanner (or something else) at once.

4) What brand should you choose: Epson, Canon, HP...?

Feed a lot more than this brand. The truth here is unambiguous - it’s impossible. First of all, I wouldn’t be surprised at a specific breeder - smut, even if it’s a common breeder of copying technology. In other words, it’s more important to look at the technical characteristics of the device and the experience of real users of such a device (it’s easy in the age of the Internet!). Even better, it is clear that someone I know recommends to you, who has a bunch of printers on his work and who knows how to work on the skin.

It’s even more difficult to name any specific model: until you read the article, this printer may no longer be on sale.

That's all for now. I will be grateful for additional and constructive comments. Usho the most beautiful 🙂

If you decide to add a printer, it will be most important to decide for what purpose you need it. Do you need a color printer or can you get by with a black and white one? Do you need a laser printer or a jet printer, or would you prefer a machine that uses solid ink? Do you need additional functions, such as wireless communication modules, copier, scanner and fax functions? Your choice depends on what you want to use on which printer, in what regard, how many people, besides you, will use the machine and, of course, how much money you are willing to spend on the addition of the device, as well as on its service vuvannya, zokrema for the addition of stained materials.

In this article we will try to give a short description of the skin type of printers that are found in nature and that can be described by the INKSYSTEM company. In addition, we are aware of the additional functions of various other devices that can make your work easier.

There are three main types of printers, which differ in the way they apply images and materials that smell like farb. The first and oldest of them is the matrix type. Such printers have practically lived for themselves, they stink, they are bulky, they move loudly, loudly, and the firebrand is just one color. They can only be used for other text documents. However, the supplies for them are even cheaper, which allows you to use these machines in offices for filling out forms and reports, as well as for affixing numbering.

Laser printers. Add expansions type. As a farb, such devices vikorystvoyutsya powder - toner. Such printers can print on any type of paper, including designer cardboard, self-adhesive and printed paper. Prints produced by laser printers have high viscosity and durability. The toner does not fade in the sun and does not wash off with water. Ideally, such printers are suitable for both fine text and thin lines, and the photo axis appears unnatural and “flat”. Another positive point is the strength of the hand. There is nothing comparable to lasers here. If such devices stand, and their maintenance is expensive, the cross-border merchants are unlikely to be satisfied with such a desire.

Strumen printers. Together with the help of rare ink. They are widely available for lasers and are available to them from the speed of the hand and the range of the selected paper. However, the power of ink grows, mixes, and in the mix creates new colors, ideal for photography. The INKSYSTEM company is widely known for a wide range of inkjet printers and printing materials before them.

Instead of laser printers, jets give their users the opportunity to save a lot on money. This is made possible by a system of continuous supply of ink or CISS. By equipping your printer with this device, you can quickly spend 30 times on each other, which will make your prints literally a copy.

Progress does not stand still, relying on wine and other technologies. Today it is no longer possible to install a device that connects a scanner, printer, copier and fax. Virologists have gone even further and began to produce devices that are not required for computer work at all. Such printers can independently reach the limit, capture images, and carry out basic correction. The buildings are constantly fighting with cameras and mobile phones. This is extremely relevant considering the current diversity of such technology.

Today, few people think about what a printer is. For everyday people this is the ultimate device. It’s true, the older generation doesn’t give a damn about why they’re doing this. So let's figure it out together.

What is it

What is a printer? If you try to break a word into parts, you can see the English word print, which means “signet”. In this way, it becomes clear that this device is the one on which to fight. More precisely, this is a machine that contains other necessary graphic and text data.

The printer is still an invisible part of everyday people. A similar innovation is a mechanical replacement of the Drukar machine. It’s easy to use such devices manually, and they’re easy to handle. Until that time, obviously, no problems appear. Now let's discuss what types of printers there are. In fact, there are plenty of them, but we can only understand the generally accepted classification of these devices.

Matrix

The main types of printers are matrix printers. The calls are large-sized plastic orbs, which are important to get richly. You can raise such a device by sublimation, however, you will be aware of the pain, even if it is small.

The robot dot matrix printer is based on the presence of a printing line and special heads. There are several heads for the help of electromagnets. When information from the computer is sent to the device, the heads begin to apply the lines to the paper, copying the information sent. The farb ends up being wasted uneconomically, and the liquidity of the mixture deprives the product of the goodness. In addition, such a device is noisy. Refilling printers with a matrix - this is on the right side of their vlasniks.

Laseri

There is a new printer - laser. It guarantees the fluidity of your hands and the good quality of the output documents. Most often, it is found in offices and centers that provide services for other documents from electronic media.

A laser printer has a robotic principle similar to a camera and other devices for creating photographs. It transmits images through lasers to a paper behind additional light-sensitive filters located in the middle of the device. During the course of work, with such modern technology, you can remove documents that are no worse than a vologist. Laser printers are refilled infrequently.

Available usim

But I’ll add one more type that can be purchased by the average person. This is a jet printer. It has less fluidity compared to laser, but the output brightness and depth of color in this model is significantly higher.

The principle of operation is similar to that of a dot matrix printer. Here the image is also formed into a dot. True, in these models it will be cut not for an additional head, but for an additional matrix, as a way of avenging a rare farb.

Cartridges in modern industrial technology can be of several types. Where should we keep in mind how much we will forgive the installation of the printer and its maintenance. The strumenevy printer may insert the cartridge “tightly”. This option is not particularly convenient, in order to use the devices again after the whole process is finished, you will have to buy and install a new cassette. Call the masters at the service centers.

There are also models in which cartridges are easily removed, and the product is poured into them through a special syringe. These are the best options. So, using the following techniques, you can refill your device. Now, if you know what a printer is and what it can do, let's take a look at the power supply modes, adjustment and installation of its equipment.

Kolyori Veselki

There are two types of current printer devices: a color printer and a black and white one. Now we will discuss the headaches and shortcomings of the skin.

Of course, perhaps the most advanced type is a black and white printer. This is the widest range of home appliances. Dosing is simple and easy with robots. Such a device can process a large number of documents without the need to replace the cartridge. The most hand-held matrix and laser models.

Another option is a color printer. This is handy for those who don’t want to go to the center to sort out their photos, and for those who value the color palette in documents. Colorful inkjet printers are often used. It’s a pity, refueling such an annex is right for the ruler. Well, the whole farb is being wasted like crazy.

Selection rules

So, if you don’t know which printer to choose, then you will inherit a bunch of brown fruits. They will definitely help you make the right decision.

Connect anything

Now that we have discovered that there is a printer, it’s time to talk about how to make money so that you can work. First, what do you need to sign out, connect him. Installing the printer is as simple as right.

If you bought a model and brought it home, you need to connect it to a personal computer. Why do you need a special wire? Vin is included with the accessory kit. Connect the cable to the printer, and then insert it into the USB port on your computer. Do not touch the device. Instead, install the Windows operating system.

Now the printer installation is half complete. It’s impossible to make money so that the computer can upgrade your device. For this purpose, you need to install a special program to allow you to work with the device for entering and displaying information. This is the required printer driver.

Installed

In order for the computer to work with the device, it is necessary to configure the printer first. For this, as has already been said, a driver is required. It is installed as a standard program on your computer. True, there are some peculiarities here. Let's get involved with them.

When you connect the printer to your computer and connections, you will need to complete the installation. To do this, insert a special disk, which is supplied with your device, into the PC drive, then follow the instructions that appear on the monitor screen. The printer settings are automatically configured. Golovne, do not try this until the driver installer asks you about it. Once the process is complete, you will be asked to unzip the first proof sheet on your printer. You will show how well and clearly the device works. Once the sheet has been cut without problems, you can then calmly use the new technology.

If the disk is ruined

You already know that a printer is the best thing to buy and fix. What's the point of working, since non-standard attacks are being caught? For example, there is no disk with the driver. It’s possible that you spent too much, or the equipment was inadequate - the reason, in essence, is not important. Golovne, that the driver is of the essence, and this means that it is impossible to work with the device.

There is no point in being angry, but even the situation can be easily corrected. You know, what model of device you bought, you can quickly surf the Internet to find out everything you need. Also, if you do not have an installation disk with a driver, check the brand and exact model of the device. After this, you need to go to the manufacturer’s website, find the “Printers” section and identify your model. After which you will have access until you download the required driver package. Own it, unpack it and install it. After which you will be able to fully exploit the equipment you have acquired.

Please try to find all the necessary additional programs on verified sites. Often, viruses are hidden under drivers on suspicious sites that can seriously damage your personal computer. So the best choice is, after all, the selection sites. There will definitely be no viruses there.

Thus, today you found out what a printer is and how to use it. Those who buy the model itself will not benefit you. Respect your preferences, consult with sellers, and you will definitely choose the right color for yourself!

With the enormous growth of printers over the inode market, it is important to consider your choice. Before heading to an office equipment store, first become familiar with the different types of printers and their characteristics. You can quickly become a manager in a store, or better yet, prepare and become a shopkeeper yourself, as long as your thoughts are not always objective.

We first need to identify important selection criteria, abstracting from others. The most important thing is not the brand of the printer or the model, but the technology of the other. Based on this criterion, printers are classified as follows: matrix, jet, laser, LED. Є a special type of printers - MFPs (highly functional), which are laser and jet printers. Russia has the widest brands: , Epson, Canon. Matrix technology is the oldest. The “head parts” of the printer work on the principle of a mechanical machine: a carriage that collapses, with another head, on a matrix of 9 or 24 heads. The little heads hang out, hitting the paper strip, leaving a mark on the paper. The size of the point, including the formation of other symbols, lies within the diameter of the matrix head. These printers did not completely survive through their unique powers: writing written on such a printer cannot be erased or corrected. Such protection from the details and the ability to hand on a roll paper is necessary for a bank, a passport office, or when selling tickets, etc. Strumen's technology is based on mitten ink through microscopic openings (nozzles), spread on a carriage that collapses, which collapses every time the paper. On an inkjet printer, use the same amount of paper between your hands that is smaller than the nozzle and stand between them. The productivity of such printers is rich. Squeeze the stench silently, shvidko. Through the micron diameter of the nozzle, the inodes are mixed with a saw, which has been rubbed, or with dried ink. That’s why the viscosity of the ink in the cartridges is important: it doesn’t take too long to dry, it smudges, and it’s not too thick—it won’t be visible to the nozzle. The ink in the cartridges comes in different colors and blacks. Its productivity is approximately 500 two-piece arches in A4 format. Laser (electrographic) generation. It is based on a photodrum that discretely discharges an electrical charge. The laser is applied to a new one, “lighting up” around the points, removing the charge from them. By controlling the exchange, you can “paint” on its surface. The surface is sprinkled with a special powder - toner, which sticks to the charged panels. Then the toner (and the little ones) is transferred to the charging paper, sticks to it and melts under high temperature. This technology provides even greater fluidity to the hand - no need to dry the ink, high reliability - the toner does not dry out over time, durability - vologists are not afraid of it. The varity of the hand is much lower than that of the strumenevom. You can use different items: papier, spittle, stickers, etc. The cost of a laser printer is high for strumenevy, especially color, color transfer girsh. Light-emitting diode (LED) technology continues “laser” technology. The main function is light. Here a whole line of light-emitting diodes is used instead of one exchange. There is a lot of it stored in a separate printer. Advantages: there is no mechanics of cervical treatment, but the skin point has its own light. There is no rust, which means that there is more reliability, fluidity (more than 40 pages per piece), and goodness (more even, without edge problems). Not very wide through very high varity. Richly functional devices (MFPs) - there are lasers and ink jets, with the functions of a printer, fax (or copier), scanner. Cost is cheaper than buying a skin device okremo. Ideal for home or mini-office.

Black and white inkjet printers are not available. Colors are handy if you need to use photographic documents with low fluidity. Their wealth of ink is great and their mutual friendliness is high. Cartridges can be refilled with ink, but printer manufacturers do not sell original ink. You can buy it from third-party producers.
