Printers characteristic principle of operation advantages and disadvantages. What is a printer? Which printer is the best? How the printer works

Printer. The history of the creation of the printer.

Printer - from the English word "print" - print.

A printer is an external peripheral device of a computer designed to display text or graphic information stored in a computer on a solid medium (paper, plastic film, etc.), without creating printed forms. This distinguishes printers from printing equipment, which is used for large print runs of texts and graphics.

A printer is a high-tech printing device designed primarily to work with a computer.

The printer is designed to convert information stored in a computing device from digital form to graphical analog form for easy understanding of this information by the user.

Prehistory of the creation of the printer.

Often the history of the invention of the prototype "printer" is associated with the name of the mathematician Charles Babbage, who in 1822 began to develop a self-printing machine. He believed that such devices would be effectively used in banking, engineering and other fields.

In 1834, Charles Babbage began work on the actual creation of the machine he designed, but he never finished it. And only 150 years later, the staff of the British Museum of Science decided to make Charles Babbage's printing machine from the preserved drawings. As it turned out, Babbage's machine turned out to be efficient, she could do the simplest calculations and print the results on paper. But this machine weighed several tons and consisted of thousands of parts!

The history of the creation of the printer.

The history of "printers" began its real movement after the invention of the first computers.

Petal printers.

In the 1950s, the first electronic computers appeared, and immediately it became necessary to display the results of the calculations performed for their visual perception and further processing. At that time, the most common device for this purpose was the typewriter, and computing centers had to maintain an entire staff of typists who pounded the keys all day.

It was then that the inventors thought about how to combine a typewriter with a computer. And so in 1953, the Remington-Rand corporation created the Uniprinter printing device, which in appearance and principle of operation resembled a typewriter, only it was many times larger than it. Such devices are called petal, because of the main printing mechanism, which looks like a flower with petals, at the end of which symbols were applied. The percussion mechanism beat on the petal, and the petal, through the tape soaked in paint, left an imprint on the paper. By replacing one "camomile" with another, it was possible to change characters or font size.

Pictured is a petal printer.

These printers printed at a speed of 78,000 characters per minute, and naturally no typist could keep up with them: the average human typing speed is 200 characters per minute.

In 1954-1955, the IBM corporation created printers with a printing speed of 100 thousand characters per minute, however, they did not differ in reliability and did not receive wide distribution. But in 1959, the IBM 1403 printer was released, with a print speed of 184,800 characters per minute. The paper flew out of the printer at such a high speed that they did not have time to collect it. This, however, did not affect the print quality in any way: it was quite high. Such devices were also produced in the Soviet Union, only they were called differently: not printers, but ADCP - alphanumeric printing devices.

Matrix printers.

Principle of printing similar to petal printers and dot matrix printers. The only difference is that the print through the ink ribbon on the paper leaves not a petal with a letter, but a print head, which forms the desired symbol from a set of small needles.

The first dot matrix printer was created in 1964 by Seiko Epson Corporation, and it was intended to print accurate time.

In 1970, Centronics Data Computer Corporation develops its dot matrix printer, and becomes their largest manufacturer for the entire decade. The printing speed of such printers was low, but they could print any complex graphics and did not need specific petals.

The first printer that can rightfully be called a home printer is the ImageWriter dot matrix printer, which went on sale in 1983 with an Apple computer and cost “only” $ 675.

Pictured is a dot matrix printer.

Since then, dot matrix printing technology has hardly changed, and if petal printers left us long ago, dot matrix printers are still successfully used. This is due to the low cost of matrix printing. All consumables: this is a ribbon spool that costs almost nothing and lasts a long time.

Inkjet printers.

Dot matrix printers gave good results when printing, but they were very noisy, and their print quality still leaves much to be desired.

The dream of a quiet, cheap printer with high print quality never left the minds of the inventors of computers.

A new step in the improvement of printers was made possible by the invention of the physicist John William Strett (Lord Rayleigh), who studied the formation of droplets in a decaying jet of liquid. These studies formed the basis of inkjet technology, which was developed in parallel with petal and matrix.

So, in 1948, a prototype of a printing device capable of printing with controlled jets of ink was created in the laboratory of the Siemens company. But it took almost a quarter of a century before truly normally functioning inkjet printers appeared in the world. All these long years, scientists have been improving the method of inkjet printing, translating theoretical ideas into practice.

In the early 1970s and mid-1980s, engineers from leading companies such as Epson, Brother, Canon and Hewlett-Packard invented three main inkjet printing methods, differing in the way ink is printed on paper.

What all these methods have in common is that in all printers there is a container with ink, at the bottom of which there is a small nozzle in which a drop of ink is formed. Further, using the piezoelectric effect or heating to high temperatures, this drop, formed in a special way, is shot onto the paper.

The first single-color inkjet printer was released by IBM in 1976 (Model 6640), and in 1977 an inkjet personal computer printer was released by Siemens.

In the early 1990s, Hewlett-Packard patented color inkjet technology. The color image was obtained by mixing three colors during printing: cyan, magenta and yellow, which resulted in a large number of shades of all colors.

Since that time, printers began to print not only black and white, but also full color images.

Pictured is a color inkjet printer.

Laser printers.

The first laser printers that hit the market in the 1980s cost more than $ 10,000, which was very expensive for the average consumer.

Laser printing technology began to develop back in 1938, when the American physicist and inventor Chester Carlson invented the electrographic printing method, which is still used in all modern laser printers and copiers.

The essence of the laser printing method is that a negative electrostatic charge is applied to the drum, which is an aluminum tube covered with a light-sensitive layer. Then the laser beam, passing along the surface of the drum, removes part of this charge in those places where you want to print. Then the drum is covered with a thin layer of toner (dry dusty paint), but only in those places where the laser beam has taken off the charge. Then comes the final part of printing: the drum rolls over the paper, leaves all the toner adhering to it on it, the paper passes through the oven, in which the toner is tightly sintered with its surface.

If you need to get a color print on a laser printer, then four colors of toner are alternately applied to the drum: black, cyan, magenta and yellow, or to get a color image, you need to print in four passes. This is how copiers and some fax machines are arranged, to which the laser printer owes its appearance.

In 1969, an employee of Xerox, Gary Starkweather, came up with the idea of using an original laser scanning mechanism in a copier, thereby turning an ordinary copier into a printer. In 1971, such a printer was created, but it was not put into mass production, and it remained within the walls of the laboratory.

Xerox and IBM are still arguing about the primacy of the release of the first laser printer. Xerox claims to have released a laser printer in 1977, while IBM claims to have done so a year earlier.

So, in the 1980s, many manufacturing firms began producing black and white laser printers, which initially cost more than $ 10,000 and had poor print quality. By the early 1990s, the price-performance ratio had become more or less acceptable, and the price of laser black and white printers had dropped to $ 1,000.

In 1993, the first color laser printer appeared, developed by QMS and costing 12.5 thousand dollars, and just two years later, Apple released a color printer already worth 7 thousand.

Nowadays, laser printers have become affordable for the average consumer.

LED printers.

With the advent and development of LED technology, models of LED printers began to be produced.

The printing technology of LED printers is also electrographic, only the laser scanning device has been replaced with a line of LEDs that runs along the drum. LED printers are easier to manufacture, smaller and cheaper than their laser counterparts, although their printing speed is almost half the size.

Pictured is an LED printer.

3D printers. 3D printers.

A new revolutionary idea in the field of printer printing is of course the so-called "3D printers" capable of reproducing three-dimensional objects. The development of "3D printers" began back in the 1980s, and then they were able to grind the workpiece layer by layer according to the principle of a milling machine to give it the proper look. Now "3D printers" have become real printers, applying polymer layers to the surface, thereby forming a volumetric relief on a flat surface.

A modern 3D printer is able to reproduce a model of a car from a polymer material, which even has wheels spinning.

The photo shows a 3D printer.

Currently, printing technologies created in the 20th century have remained unchanged. Basically, the scope of application of printers and the types of surfaces on which modern printers can print have changed and expanded significantly.

If you decide to purchase a printer, the most important thing is to decide for what purpose you need it. Do you need a color printer or can you just get by with black and white printing? Do you need a laser printer or an inkjet printer, or maybe a solid ink machine is better for you? Do you really need additional functions such as wireless modules, copier, scanner and fax functions? Your choice will depend on what you want to print on this printer, to what extent, how many people besides you will use the device and, of course, how much you are willing to pay for the purchase of a printing device, as well as for its further maintenance, in particular, for the purchase of consumables.

In this article we will try to give a brief description of each type of printers that exist in nature and that INKSYSTEM can offer. In addition, we will tell you about the additional functions of some printing devices that can greatly facilitate your work.

There are three main types of printers, which differ in the way they apply the image and the material they use as ink. The first and most ancient of these is the matrix type. Such printers have practically outlived their usefulness, they are bulky, print loudly, slowly, and most importantly - only in one color. They can be used exclusively for printing text documents. However, consumables for them are extremely cheap, which makes it possible to use these devices in offices to fill out forms and certificates, as well as for numbering.

Laser printers. Quite a common type. As a paint, such devices use fine powder - toner. These printers can print on any type of paper, including designer cardboard, self-adhesive and transparencies. The prints made by laser printers are of high quality and durability. Toner will not fade in the sun and will not be washed off with water. Ideally, these printers are suitable for printing small text and thin lines, but the photos are unnatural and "flat". Another positive point is print speed. Nothing beats lasers here. However, such devices, as well as their maintenance, are quite expensive, so ordinary users will hardly be able to afford such a luxury.

Inkjet printers. Printed with liquid ink. They are much more affordable than laser ones, inferior to them in print speed and range of paper used. However, due to the ability of the ink to spread, mix and create new colors in the place of mixing, they are ideal for photo printing. INKSYSTEM is widely known for its wide range of inkjet printers and consumables.

Unlike laser printers, inkjets give their owners the opportunity to significantly save on printing. This allows a continuous ink supply system or CISS. By equipping your printer with this device, you can reduce your printing costs by 30 times, which will make the cost of your prints literally a penny.

Progress does not stand still, it also affected printing technology. Today it is hardly possible to surprise someone with a device that combines a scanner, printer, copier and fax. Manufacturers went even further and began to produce devices that do not need a PC at all to operate. Such printers can independently go online, download images from there, and carry out elementary corrections. They are capable of printing directly from cameras and mobile phones. This is extremely relevant, given the variety of such technology today.

A printer is a device used to print information from an electronic form onto paper. In this case, the process of transferring data to paper is called printing, and the result is a printout. The printer can perform several functions, so the selection process should be approached carefully, having thoroughly familiarized yourself with its functions. It is necessary to take into account all the peculiarities of printing, for example, an office model for the home will not be the best option, since you do not need a large volume of printing, and there is no need to purchase a universal printer either.

Types of printing devices

Today there are two types of printing devices that differ in their functionality:

Multifunctional.
Printers.

The first type is called MFP for short. It is usually chosen for home, in addition to printing information on paper with this device, you can scan documents to save the result in electronic form, you can use it as a regular copier for simple copying of documents, and also as a fax.

This all-in-one device is less expensive than a printer, copier and scanner purchased separately. In addition, with such a purchase, you will save space on your computer desk, and there will be fewer wires. If, apart from printing text on paper, you do not need anything, then the second type of device will be the best choice.

Types and features of the device

The range of printers is very large today. They differ in many ways - purpose, type of ink, number of colors, principle of operation, etc. Each of the species has its own characteristics and auxiliary functions. Let's consider the main types of printers in more detail.

Matrix

This type of printer was developed in Japan in the 60s of the last century.

Its principle of operation is to create an image with a special print head, which consists of a matrix, hence the name of this device. The matrix consists of a set of needles driven by electromagnets. The print head moves along the sheet of paper for each line of text, and the needles act on the paper through the ink ribbon, thereby creating a dot print on the sheet.

In different models, the print head can have from 9 to 24 needles. The more pins, the higher the print quality and the sharper the image. Dot matrix printers have already been practically superseded by other modern printers, but are still used in some places. For example, sales receipts in stores are printed using a matrix method.

Insufficient quality, like a typewriter, no longer makes it possible to apply matrix technology in other areas. Among the disadvantages of such devices, in addition to poor quality, one can distinguish noisy operation and low printing speed.

The advantages of this rare design is the ability to function in any conditions, needle prints are resistant to moisture and abrasion. It is quite difficult to counterfeit a document printed on a dot matrix device.

Jet printer

The principle of operation of an inkjet device is somewhat similar to matrix technology: the image is also formed from dots. Instead of a needle print head, a matrix of liquid dyes is used.

It can be fixed in the body of the device, or built into the cartridge. The “jet-skippers” are divided according to some typical characteristics.

If we consider their division by type of ink, then they are divided into:

Aquatic(used in many office and household devices).
Oil(for marking in industry).
Solvent(for printing stands, advertisements and various posters, moisture resistant).
Pigment(the best way to create quality images, photos).
Thermal transfer(for applying fashionable prints to clothes).
Alcohol(dry quickly in the print head, which limits their use).

There are types of inkjet printers by purpose:

Office(they are equipped with offices for printing small documents).
Widescreen(for advertising printing).
Marking(parts are marked).
Interior(printing of stands, posters, interior elements).
Photo printers.
Souvenir(printing images on laser discs, objects with a complex surface).
Manicure(drawing is applied to nails in beauty salons).

Photo printers and office printing devices are equipped with one head for each color, have high-quality color reproduction, do not create noise. High image quality can only be achieved when using special paper.

The performance of inkjet printers is slightly higher than matrix printers, the image is sensitive to moisture, may be smeared, depending on the type of ink, fading over time. An inkjet printer is a moody device that will work just fine if you use all the cartridges on a regular basis. If the device has not been turned on for a long time, the ink in the head may dry out.

The main negative factor is the high cost of printing. The ink in the cartridge runs out quickly and needs to be replaced periodically, which is expensive. This problem is partially solved by the following device in question.

CISS

This device can easily replace the work of cartridges, its name stands for continuous ink supply system. The principle of operation of this system is to supply ink to the cartridge through tubes.

This improves print quality and you can save money by not purchasing expensive ink cartridges. It is only necessary to purchase ink on time and pour it into containers, which is much cheaper and lasts for a longer time.

To refuel this system, you do not need to contact a specialist, you can do everything yourself. Previously, this system was sold separately, but now it is built into many printer models.

Laser technology

It would be more correct to call this method of printing electrographic, it appeared in 1938, and was then called xerography and electrography. Currently, this method is called laser printing, which is characterized by high quality, economy and high speed.

The main element of this device is a photoreceptor, which stores a charge of electric current on its surface; there is a separate charge for each point of the image. The laser beam hits the photoreceptor, made in the form of a drum, and directs the radiation to individual points from which it removes the charge. A computer connected to a laser printer controls the laser beam and creates a specific image on the drum.

A special powder dye enters the photoreceptor and sticks to its charged areas, creating an image, which is then transferred to paper and baked on it by heating.

This technology has proven itself to be faster than inkjet models. The print quality of the laser printer is high, the image is not subject to abrasion, is resistant to moisture, does not fade, unlike the previous models reviewed. The advantage of laser technology is also the ability to print on any paper with excellent quality.

A laser printer has its drawbacks: high cost, which is offset by cheaper refills and maintenance. The disadvantage can also be attributed to some distortions in the printing of letters and images on the edge of the sheet - the point sometimes turns out in the form of an oval. Modern models no longer have this problem by using special technological lenses.

LED technology

This method can be considered a kind of laser printing, with a difference in the light source. Here, instead of a laser beam, LEDs are used. In the image, all the dots correspond to individual LEDs that do not move like a laser.

This improves operational reliability and is an advantage. Another advantage can be called high speed - printing speed can reach 40 sheets per minute, and the print quality is much higher compared to laser printing, since there is no distortion at the edges of the sheet. The only drawback is its high cost.

Rarely used types of printers

There are many different printing technologies that are not widely used or are used for narrow specialization.

Sublimation the printer is an alternative option for inkjet models, rarely works in offices, but is successfully used in the printing industry, has good image quality and color reproduction.

Drum devices that worked before are no longer used, their design is outdated, but the printing speed of these devices surpasses all existing types of printers. Its main element is a drum, which has the dimensions of a sheet, and on the surface has reliefs of numbers and letters. The operation of the device is as follows: the drum rotates, and when the desired number or letter passes over the sheet, a special pusher hits the sheet, printing a symbol on the paper with an ink ribbon. Printed sheets on such a printer can be easily recognized - the font is similar to that of a manual typewriter, with characters "jumping" in height.

Petal the printer works in a similar way, with the difference that the character set is on flexible petals on a rotating disc. The desired petal touches the ribbon and paper to create a print. Colored text can be obtained by setting the ribbon to a different color.

Throughout the history of development, printing devices were of the following types: chain, caterpillar and ball. They differed in the principle of operation, but were not widely used.

Home or office printer. The difference between them is only in the volume of printing. Up to 500 sheets per month are enough for home, but for office work this will not be enough. Therefore, laser models are purchased for the office, and inkjet models are preferable for the home, although everyone chooses for himself.
Print quality. This parameter is individual for each user. There is a parameter that determines the clarity and quality of the printout - this is the resolution. For office work, a printing device with a resolution of 600 to 2400 pixels per inch is suitable. Almost all modern devices today have sufficient resolution to work in any conditions.
Printing cost. When choosing a printer, you need to look at both the price of the device itself and the costs required to maintain and refuel it. If you require a little printing, then it is better to get an inexpensive device designed for a small load. If you need to print a large volume of documents, then the best choice would be an expensive printer with a large load capacity. The price also depends on the number of additional functions: built-in memory, auxiliary trays, wireless connection to a computer, etc.

Most of the population of our planet is firmly convinced that all existing printers are divided into two categories: ordinary and "those that can print, copy and scan", in other words, they do any printing processes. However, in fact, this type of office equipment has many different classifications, the existence of which many do not even know.

This article is dedicated to all types of printers - from the most primitive to the most modern. It tells about what they are, their positive and negative sides, purpose and the possibility of acquiring today. It also describes a lot of interesting, and most importantly useful information and, as a conclusion, the expert opinion of leading specialists in the field of printing technologies.

Types of printers

Today there are more than ten different classifications of printing devices. In addition, each class has its own division into types, and as a result, it turns out that there are an innumerable number of different printers. But for a more comfortable determination of the belonging of these products, they are classified according to the following parameters:

type of printing: alphanumeric and graphic;
the principle of creating prints: percussion and non-percussion;
print color: monochrome and multicolor;
source of connection: wired and wireless.

It is worth knowing that some of the office equipment has not been used for a long time, and some devices even exist only in future projects.

Most commonly found printers on sale

As mentioned above, there are many varieties of these peripheral devices, but not all can be purchased in the store and brought to your home or office. The most popular and most often found are laser, inkjet and dye-sublimation printers. Each of them has its own distinctive features, in some way superior or inferior to each other.

Laser printer: conquering the office

From the first days, as soon as this type of office equipment became available to everyone, and until today, a laser printer is an integral part of any office. This is due to the high speed and excellent print quality in black and white. In addition, there are good reserves of dye in, which, as a rule, are enough for a long time of use. However, "lasers" have not proven themselves in the best way in color printing of images and photographs. It is also worth noting that refueling consumables is not very convenient, expensive, and sometimes completely impossible.

Why is an inkjet printer many times more comfortable to use at home?

Compared to the previous type of office equipment, this one creates prints very slowly and many times fewer pieces without refueling. But instead, the material printed with it is always high quality, especially if it is in color. In addition, such devices are usually multifunctional, which, given the relative cheapness of consumables, makes them indispensable for home use.

Next Generation Dye Sublimation Printers

Provides superior print performance, resulting in excellent color, brightness and contrast, easy maintenance and low noise. However, they have one very unpleasant property: materials printed with their help are very sensitive to ultraviolet radiation.

Based on the information provided in this article, we can conclude that any printer, no matter what you take, has both pros and cons. Therefore, when choosing this device for yourself, you should start from what you will use it for and whether it will be able to cope with the tasks set.

The printer is a conveyor belt serving the office and an indispensable assistant at home, if you are. Electronic documents and communication over the Internet are, of course, good, but no 21st century can force a person to abandon paper. Print a signature agreement, term paper or just photos to frame and hang on the wall - you can't do without a printer.

In this article, we will give a brief overview of the types of printers, try to compare them and understand which ones are better, and also give advice on which printer is better to buy.

What types of printers are there?

The most important thing to remember if you are interested in what printers are and what they are: all printing devices are based on the same principle - they form an image on paper from dots.

What distinguishes them from each other is the principle of transferring an image from a PC to a paper sheet, as well as the type of material that they use as paint. In addition, they differ in purpose. We will now tell you about all the differences.

Types of printers: device

In terms of design and operating principle, there are three types of printers: dot matrix, inkjet and laser.

Matrix printer is an obsolete printer type. Its work is carried out as follows: the print head, consisting of a set of needles (matrix), moves line by line along a sheet of paper, and the needles strike it through the ink ribbon in a certain order, leaving points from which the image is formed. About 20-25 years ago, this was the main type of printers, and now they are used in cash registers - for printing receipts. And also our passports are printed on dot matrix printers!

Jet printer works similarly to a matrix one, only instead of needles it has a matrix with holes through which ink is sprayed pointwise - black or colored. An image is formed from dots of paint. Ink is supplied in special modules - cartridges, which must be purchased separately. There is also a continuous ink supply system (CISS): a special print head is built into the printer, to which ink is supplied from reservoirs through thin tubes. In this case, it is enough to periodically buy ink and refill them in the tanks.

Laser printer uses an electromagnetic charge for printing, which is created using a laser beam on a special part - a photo drum. Individual dots on the drum are charged with a laser, due to which a special dye composition (toner) sticks to them, and then it is transferred to the paper. After the formation of the image, it is fixed in the "oven" - a system with two shafts, one of which is heated to a temperature of about 200C.

Printer types: purpose

If you list each type of printer by purpose, you get a fairly small list. The fact is that only inkjet and laser printers can have different purposes: the field of application of matrix printers - checks, passports, bank receipts.

In addition to household printers that are used for printing at home, printers are divided into:

Office. As a rule, these are either fast black-and-white printers, or powerful multifunctional devices (MFPs) that combine a printer, scanner, copier - everything that can be useful when working with documents.
Large format (plotters)... They are used to print outdoor advertisements - large banners, posters, stand advertisements and other things of this kind.
Marking. They are used in retail: they are used to quickly print all kinds of labels that are applied to goods.
Sublimation printers... They are used to print with special inks on materials other than paper, such as T-shirt prints.
Photo printers... Everything is clear here - these printers are designed to print high quality photos.

Girls who often visit beauty salons will also tell you that there are manicure printers. They are used to print ... nail art. This is where the technique has come!

Which printer is the best? Advantages and disadvantages

If we compare different types of printers with each other, then oh dot matrix printers speech is probably not worth it - they have too narrowly specialized application. We can only say that they print slowly, with a characteristic unpleasant sound, rather pale and, most importantly, only in one color, which is set by the printer manufacturer (usually black or blue).
Inkjet printers By the way, in terms of print speed they can differ from matrix ones by only a few seconds. But they are much quieter, have wider applications and are capable of printing in different colors. At the same time, an inkjet printer is a gadget known for its capriciousness. They need to be used regularly so that the ink in the cartridges does not dry out; you cannot use too thin or too thick paper with it - it may get stuck in it (a fairly well-known bug). But the biggest drawback is the high cost of maintenance: the ink in the cartridges and CISS tanks ends up pretty quickly, and you need to constantly buy it.
Have laser printer on the contrary, high print speed - 10-20 pages per minute. It is quite noisy, but extremely versatile. An interesting advantage of a laser printer is its ability to print on almost any paper, such as thermal transfer paper or tracing paper. The disadvantage of the "laser" is the high cost (although it is not known whether this is a drawback or an advantage: a laser printer is more expensive to buy, but much cheaper to maintain - toner runs out slower), as well as the difficulty of refilling: if you can insert a cartridge into an inkjet printer yourself, to replace the toner in laser often has to invite a specialist.

How Do I Pick a Good Printer?

It is worth choosing a printer, first of all, taking into account what and in what volumes you need to print. This is the main characteristic, but here's what else you need to consider in order to choose the device correctly:

Printer type and purpose... We talked about them above.
Chromaticity... Which printer do you need - color or black and white?
Paper size... Variants from A0 to A6 and smaller are available.
Duplex printing capability... If there is one, the printer will automatically "flip" the sheet to continue printing on the other side. This saves paper.
Interface... Typically, the printer connects to a PC via USB, but there are options for connecting via Wi-Fi, Ethernet, and even using NFC.
Photo printing possible... This is a separate topic. It is not necessary to purchase a professional photo printer to print photos - a good home printer will do it too.
Availability of CISS... As already mentioned, this is a special ink supply system. It can be sold with the printer - then its maintenance will cost you much less.
Print speed... The home printer is capable of delivering from 8 to 38 sheets per minute. Decide how quickly you need your printed documents.
