Matrix printer
Matrix printers are the oldest types of printers currently in use, their mechanism was invented in 1964 by the Japanese corporation Seiko Epson.
The image is formed by the print head, which consists of a set of needles (needle matrix) driven by electromagnets. The head moves line by line along the sheet, while the needles hit the paper through the ink ribbon, forming a dot image.
There are also high-speed line matrix printers, in which a large number of needles are evenly spaced on a shuttle mechanism (frette) across the entire width of the sheet.
Matrix printers, despite their complete displacement from the household and office sectors, are still widely used in some areas (banking - carbon copy printing, etc.).
The principle of operation of a dot matrix printer
The principle of operation of a dot-matrix printer, which uses sequential impact dot-matrix technology, is as follows: during operation, the print head moves along the carriage, and the image is formed due to the dots produced on paper due to the needles touching the ink ribbon. The needles are arranged in groups of 9, 12, 14, 18, 24, 36, or 48 in vertical rows. The material for the needles is wear-resistant tungsten alloy. The ink ribbon is usually made of dense nylon.
There is another principle of operation used in line matrix printers, which are popular in large organizations.
The main part of a line matrix printer is a structure consisting of a frame with a printing width, on which printing hammers are installed horizontally along the entire length, combined into modules - frets. During operation, the frame, driven by a crank mechanism, reciprocates with a high frequency and amplitude equal to the distance between adjacent hammers. Depending on the number of hammers in the fret, the speed changes - those printers, where the number of hammers in the fret is greater, have a higher speed.
When the shuttle moves from one dead point to another, the hammers, in those places where required, apply images on paper due to the impact on the ink ribbon, forming a complete horizontal line of the given image in each pass. The paper then advances one step forward and the shuttle returns in the opposite direction, forming the image line by line.
The print speed of a printer is measured in lines per minute when printing text, or in inches per minute when printing graphics.
Technologies that drive the needle or hammer of a dot matrix printer are divided into:
ballistic
stored energy printing technology.
ballistic
Ballistic technology is based on electromagnets located on each of the needles. When the electromagnet is energized, it attracts the "heel" of the needle (implementations may vary depending on the manufacturer) and it is set in motion. The needle returns to its original position under the action of a spring.
Stored Energy Technology
The spring at rest is stressed by the action of a permanent magnet. When printing, the magnetic field of the coil through which the current was passed compensates for the field of the permanent magnet. This compensation is sufficient for the spring to break away from the magnet and the needle to move. When power is removed from the winding, the spring is again attracted to the permanent magnet, returning the needle to its original state.
Stored energy technology is newer than ballistic technology, and its main advantage is that the head heats up less during operation, since noticeably less power must be applied to the coil to compensate for the strength of the magnet than when the electromagnet drives the needle. Another advantage is that the impact force of the needle hardly changes with time or heat, because in the head with stored energy it depends only on the stiffness of the constantly bent spring. But the print heads, which are made using ballistic technology, are noticeably smaller in size - this allows you to save energy on their movement along the carriage, as well as make more powerful heat exchangers on them.
Flaws:
monochrome (although there were also color matrix printers, at a very high price)
very low speed
high noise level, which can reach 25 dB.
Advantages:
Low cost of the printer and the cost of consumables;
Printing multiple copies via carbon paper
Matrix printing, which uses the oldest technology, is now practically not in demand in personal home use. However, in a number of areas it is still not possible to replace it, which leaves it still in demand - this is banking, carbon copy printing, printing of multi-copy forms; pin envelopes for SIM-cards and bank cards; air tickets; printing on responsible forms and forms, where the fact of applying information by impact is important.
All printers, whether dot matrix, inkjet, laser, do essentially the same job: they create a combination of dots on a sheet of paper. Dots can be of different sizes and colors, printing ink is applied to paper too different ways, but absolutely all images, whether text or drawing, are made up of dots. The smaller the dots, the more impressive the end result.
The principle of operation of a dot matrix printer
|
Permission - 72 - 360 dpi Number of colors - One color (although there are dot-matrix printers with multi-color ink ribbon) Performance - up to 1500 lines per minute |
Like a typewriter, a dot matrix printer has a print head that moves in a carriage along a sheet of paper. The electrical signals from the processor, after being amplified, are sent to the printer head. The head contains from 9 to 24 printing needles, the ends of which are lined up in a vertical line. The other ends enter the electromagnet. The current from the processor activates the solenoid, which creates a magnetic field; the latter repels the magnet at the end of the needle, causing the needle to move towards the paper. A moving needle strikes a tape soaked in paint. The force of the impact transfers the ink to the paper on the other side of the ribbon. After hitting the tape with a needle, the spring returns it back to its original position. The printer head continues to fire different combinations of needles as it moves along the page, so that all characters are formed from vertical dot patterns. On some printers, you can improve print quality or thicken lines by passing the printer a second time over the same line, which will print a second set of dots slightly offset from the first. Special protection prevents excess dye from getting on the paper. |
How an inkjet printer works:
|
Permission - up to 1440 dpi Number of colors - One color (black) or four colors (CMYK print model) Performance - Text printing is 3-4 ppm, graphics printing is longer |
The print head moves relative to the stationary paper without touching it. On the print head of an inkjet printer, instead of needles, there are special holes - nozzles through which ink is sprayed onto paper. A drop of dye can be shot out of the nozzle either due to the piezoelectric effect, or due to the pressure of vapor bubbles that occurs when the ink is heated. Various Models printers have from 12 to 256 nozzles. The size of each nozzle is significantly smaller than the diameter of the needle, which provides greater image clarity. |

Specifications printers:
Term permission (resolution) is used to describe the contrast and quality of a printed sample. In all the printing technologies under consideration, an image is created by reproducing dots on paper. The resolution of the printer, and hence the print quality, depends on the size and number of these dots. When viewing a page printed at low resolution on a dot matrix printer, you can see with the naked eye a pattern of dots forming characters. This is because the dots are quite large and have the same size. And when viewing a page printed at high resolution on a laser printer, the characters appear "solid" because the dots are much smaller and typically vary in size.
Printer resolution is usually measured in dots per inch ( dots per inch - dpi), in other words, this is the number of individual dots that the printer can print on a line one inch long. In most printers, resolution is defined in two directions - vertical and horizontal.
For example, a resolution of 300 dpi means 300x300 dots per square inch, i.e. the printer can print 90,000 dots per square inch of paper.
Of course paper quality affects the printed image. Since with laser and inkjet printing If you use a variety of media (dry toner and liquid ink), you need to be very careful with your choice of paper, especially if high-quality, photo-quality printing is expected. An incorrectly selected paper type may cause smearing of the printed image or other defects, such as loose toner particles. For special types of printing, there are currently specialized types of paper: for example, to print at 720 dpi photographic quality on an inkjet printer, you need to purchase special paper - smoother and faster drying.

A dot matrix printer is a printing computer peripheral with an impact mechanism that forms an image on paper consisting of individual small dots. The dot matrix printer mechanism was developed by Seiko Epson engineers in 1964. Thus, these devices are the oldest on the market of printed office equipment.
The principle of operation of the matrix mechanism is as follows: microscopic tungsten needles, arranged in a certain order (one or two columns or in the shape of a rhombus) on the print head (matrix) located on the carriage, are actuated by electromagnets and, moving along the transverse guides, in a given sequences hit the ink ribbon packed in the cartridge. As a result, tiny dents are formed on the paper, filled with toner. Their arrangement forms the text or picture. The quality and speed of printing depends on the number of needles.
The most common are 9- and 24-needle models. The 9-needle head heats up less, but does not provide much good quality print. To increase print speed, some manufacturers equip dot matrix printers with dual and quad 9-pin heads.
24-needle printers allow higher resolution printing, but are much slower. Currently, they are in demand in very narrow areas.
In order to be able to print media of different thicknesses, dot matrix printers have a manual or automatic function for adjusting the gap between the paper roller and the print head.
The matrix printer cartridge contains a nylon ink ribbon about 6 m long and knots for its pulling and tension. A shorter tape is tinted with a felt roller impregnated with paint or a special hopper.
Dot matrix printers support alphanumeric and graphics modes. However, when playing graphics, the print speed drops noticeably.
The most popular dot matrix printers were in the 70s and 80s of the last century. The first devices in the process of work made loud, unpleasant sounds. Subsequently, the design of these devices has been improved in the direction of reducing noise and increasing print speed.
Currently, they have been supplanted by inkjet and laser printers, but there are areas of activity where dot matrix printers are still used and, apparently, will be used for quite a long time. These are shops, banks, payment terminals, post offices, ticket offices, computer centers, financial hotels of various institutions where streaming printing is performed.
Accordingly, in most cases, for printing on dot matrix printers, receipt tape or rolled or folded perforated paper. Sheet paper is also used, but requires manual refilling. Only some models have the option of auto-feeding paper sheets.
The use of dot matrix printers provides acceptable print quality at a fairly low cost. Currently, these devices continue to be produced by Star, Epson, Citizen, Okidata, and others.
There are two types of dot matrix printers:
1. sequential-matrix (dot-matrix) - contain 9 needles arranged in one row, 18 needles - in two rows or in the form of a rhombus, or 24 needles - in two vertical rows; rows of characters are formed as a result of the movement of the head across the paper;
2. line matrix - thanks to the modular arrangement of needles on spring legs and the shuttle mechanism, all dots in a line are printed at the same time, then the paper is shifted vertically, the next line is printed, etc. This method is the most efficient in terms of printing speed (1400-1800 lines per minute), besides, line matrix printers produce less noise during operation.
Dot matrix printers can print in color. For this, cartridges with four CMYK ink ribbons are used, which make it possible to obtain a seven-color image. In this case, four primary colors are printed in one pass, and three additional colors in two passes.
Of course, dot-matrix printers are not designed to produce color photorealistic images, they are suitable for printing simple graphics and colored text. In addition, when in contact with black, the primary colors on the tape are gradually contaminated, resulting in color degradation.
But, despite all the shortcomings, dot-matrix printers also have undeniable advantages that allow them to still be in demand. The main advantage of these devices is the formation of a stable image that cannot be washed off, erased or etched, because the trace of the needle will still remain.
In addition, dot-matrix printers are economical, simple design, high reliability, long life, easy operation and Maintenance, unpretentiousness in paper quality, the ability to simultaneously print multiple copies using carbon paper and the long life of the ink ribbon, which is designed for 8,000,000 characters.
MATRIX
Dot matrix printers are the oldest type of printer currently in use, its mechanism was invented in 1964 by Seiko Epson Corporation. Dot matrix printers were the first devices to provide hard copy graphic output.
Matrix printing is now practically not in demand in personal home use. However, in a number of areas it is still not possible to replace it, which leaves it still in demand - this is printing of multi-part forms; pin envelopes for SIM cards and bank cards; air tickets; printing on responsible forms and forms, where the fact of applying information by impact is important.
Let's take a closer look at the technology itself.
The image is formed by the print head, which consists of a set of needles (needle matrix) driven by electromagnets. The head moves line by line along the sheet, while the needles hit the paper through the ink ribbon, forming a dot image. This type of printer is called SIDM. Serial Impact Dot Matrix - sequential impact matrix printers). Printers were produced with 9, 12, 14, 18 and 24 needles in the head. The main distribution was received by 9 and 24 needle printers. The quality of printing and the speed of graphic printing depends on the number of needles: more needles - more dots. Printers with 24 pins are called LQ. Letter Quality - the quality of the typewriter). There are monochrome 5 color dot matrix printers that use 4 color CMYK ribbon. Color change is performed by shifting the ribbon up and down relative to the print head. The print speed of dot matrix printers is measured in CPS. characters per second - characters per second).

The principle of operation of a conventional dot-matrix printer, which uses sequential impact dot-matrix technology, is as follows: during operation, the print head moves along the carriage, and the image is formed due to dots produced on paper due to needles touching the ink ribbon. There is another principle of operation used in line matrix printers, which are popular in large organizations.
The main part of a line matrix printer is a structure consisting of a frame with a printing width, on which printing hammers are installed horizontally along the entire length, combined into modules - frets. During operation, the frame, driven by a crank mechanism, reciprocates with a high frequency and amplitude equal to the distance between adjacent hammers. Depending on the number of hammers in the fret, the speed changes - those printers, where the number of hammers in the fret is greater, have a higher speed.
When the shuttle moves from one dead point to another, the hammers, in those places where required, apply images on paper due to the impact on the ink ribbon, forming a complete horizontal line of the given image in each pass. After that, the paper moves forward one step, and the shuttle returns in the opposite direction, forming an image line by line. The print speed of a printer using this technology is measured in lines per minute when printing text, or in inches per minute when printing graphics. The tape is fixed at an angle relative to the frame, which makes it possible to wear fairly evenly. When printing, it moves either in one direction, go in the other direction, rewinding from reel to reel. With this method of printing, if printing is carried out on paper of small width (A4 format), the tape wears out unevenly - only one half of the tape wears out. If there is a reasonable need for such printing, it is recommended to turn the spools over from time to time in order to make one or the other halves of the ink ribbon work alternately.
Technologies that drive the needle or hammer of a dot matrix printer are divided ballistic and stored energy printing technology. In the first case, the needle is drawn into the electromagnet, like a core into a coil through which current passes, and the spring strung on the needle is compressed. After turning off the current, the needle returns to its place thanks to the spring. In the case of stored energy technology, the spring is stressed at rest by the action of a permanent magnet. When printing, the magnetic field of the coil through which the current was passed compensates for the field of the permanent magnet. This compensation is sufficient for the spring to break away from the magnet and the needle to move. When power is removed from the winding, the spring is again attracted to the permanent magnet, returning the needle to its original state. Stored energy technology is newer than ballistic technology, and its main advantage is that the head heats up less during operation, since noticeably less power must be applied to the coil to compensate for the strength of the magnet than when the electromagnet drives the needle. Another advantage is that the impact force of the needle hardly changes with time or heat, because in the head with stored energy it depends only on the stiffness of the constantly bent spring. But the print heads, which are made using ballistic technology, are noticeably smaller in size - this allows you to save energy on their movement along the carriage, as well as make more powerful heat exchangers on them.
The main disadvantages of dot matrix printers are: monochrome, low speed and high noise level, which reaches 25dB. To eliminate this shortcoming, some models provide a quiet mode, but the print speed in quiet mode drops by 2 times, since in this case each line is printed in two passes using half the number of needles. To combat noise, special soundproof casings are also used. Some models of 24-pin dot matrix printers have the ability to print in color through the use of a multi-color ink ribbon. However, the resulting color print quality is significantly inferior to the print quality of inkjet printers. Dot-matrix printers are still widely used today due to the fact that the cost of the resulting printout is extremely low, since cheaper folded or rolled paper is used. The latter can also be cut into pieces of the desired length (not formatted). Some financial documents must be printed only through carbon paper, to exclude the possibility of their forgery.
High-speed line matrix printers are also produced, in which a large number of needles are evenly located on the fret across the entire width of the sheet. The speed of such printers is measured in LPS (eng. Lines per second lines per second).
Dot-matrix printers, despite being considered obsolete by many, are still actively used for printing (mainly using continuous paper feed, on rolls) in laboratories, banks, accounting departments, in libraries for printing on cards, for printing on multilayer forms (for example, on air tickets), as well as in cases where it is necessary to obtain a second copy of the document through a carbon copy (both copies are signed through carbon copy with one signature to prevent unauthorized changes to the financial document).
For decades, dot-matrix printers have been in demand and even indispensable in businesses that need low-cost streaming printing. Stores, banks, service centers, financial departments, scientific institutions - we encounter dot matrix technology everywhere that prints on continuous ribbons or multi-copy forms. We see the font of the dot matrix printer on sales receipts, invoices, receipts, air tickets. In addition, matrix devices are ideal for printing technical and financial reporting.
Why dot matrix printers occupied this niche? What are their advantages and disadvantages? When is dot matrix printing more profitable than laser printing and what type of dot matrix printer should you choose for your business? Below you will find answers to these questions and will be able to understand dot matrix printer specifications.
How it works and a bit of history
The idea of typing text not from ready-made characters of a typewriter, but from individual points, received its first large-scale implementation in the 1960s and formed the basis of dot-matrix, and then of all modern printing.
The fundamental difference between dot matrix printers from the later inkjet and laser in how dots are applied to paper.
Dot matrix printers the image is embossed by striking small needles through the ink ribbon. When hitting a sheet, the needle presses a tiny section of the ink ribbon against it and leaves an impression filled with ink.

By the beginning of the 1990s, when relatively more than quiet inkjet printers with high print quality, the use of dot matrix printers has sharply narrowed. But due to the high fault tolerance, availability and ease of use, matrix devices remained indispensable in production and commercial institutions.
Modern dot matrix printers are less noisy, print faster and better than their predecessors, and continue to deliver in-line printing success in the enterprise.
Success Secrets
Firstly, dot matrix printers simple in design, which means they are reliable and do not require complex maintenance. When it comes to the huge volumes of everyday printing, this advantage is one of the decisive ones.
For example, Epson LQ 24-dot matrix printers The 2100 series are renowned for their resilience, with a print head life of 400 million dots per stylus! The resource of the ink ribbon is also impressive - it allows you to print up to 8 million characters.

Secondly, dot matrix printing costs many times cheaper than laser, inkjet or solid ink. This is the most economical way to present information in printed form. An ink ribbon for a dot matrix printer costs much less than the amount of ink and toner required to refill one cartridge.
Thirdly, dot matrix printers can work with paper different type and format: from sheet-folded to continuous tapes and cardboard. Continuous printing can significantly speed up the production of standard forms, which is important in ticket offices, banks, service centers or stores where you need to quickly serve the customer. In addition, dot matrix printers can create multiple identical copies of a document at the same time. For this, printing on carbon paper is used.
Various dot matrix printer models support a different number of copy layers. For example, the OKI Microline 3311e 9-pin printer can create up to 5 copies of a document at a time (original + 4 copies).
In addition, the imprint made on dot matrix printer cannot be completely washed away. In any case, the imprint of the needle remains on the paper. This helps to establish the authenticity of accounting or other financial records.
Dot matrix printing types
Dot matrix printers are dot-matrix and line-matrix. In fact, they differ in print speed, noise level and maximum continuous operation time. The technical difference between them is, first of all, in the structure and method of moving the print head.
In production or department big company the determining factor when choosing a printer is usually the ratio of reliability and cost of ownership. The total cost of ownership is directly related to the cost of consumables and repair costs. Line matrix devices, with cheap consumables and a reliable design, are always more economical than dot matrix and, especially, laser printers.
Line Matrix Printers are convenient in that they provide the greatest cost savings at high print volumes.
Instead of a conventional movable print head, line matrix printers use a so-called shuttle. This is an assembly of blocks with printing hammers, capable of covering the entire width of the page. During the printing process, the hammer blocks move quickly from side to side.
If a dot-matrix printer moves the print head across the entire sheet, the shuttle blocks move a tiny distance equal to the gap between the hammers. As a result, they form the entire line of points entirely. The paper then feeds forward and the next line starts printing.
That's why print speed for line matrix printers measured not in characters, but in lines per second (LPS - Lines per second).
shuttle line matrix printer wears out much slower than the dot matrix print head. It does not move itself, but only a part of it, and the amplitude of movement is relatively small. The ink ribbon of the cartridge is also more economical: it is at an angle to the printing hammers and is rewound between two bobbins, so that its surface wears out evenly.
In addition, line matrix printers typically have advanced administration capabilities. Many of them can be connected to the office network and combined into groups for remote centralized management through special software.
Designed for large enterprise, line matrix printers have good upgrade potential.
Among options for line matrix printers: sheet and roll automatic feeder, paper stacker, zero-tear device, pull tractor for more layers of multicopy printing, Network Card, curbstones with additional trays for papers.
Epson offers interface cards for both wired and wireless network connections.
With such a variety of add-ons, it will not be difficult to choose the optimal configuration for your needs.

Reliability of OKI dot matrix printers so high that the manufacturer gives a 3-year warranty when purchased from authorized dealers.
Print quality
Any printing technology puts us in front of a choice between speed and quality. And dot matrix printing is no exception.
Dot matrix quality depends on the ratio of speed and resolution. There are three levels of quality:
- LQ (Letter Quality)– high quality matrix printing, which is provided by 24-pin printers;
- NLQ (Near Letter Quality)- medium quality. On 9-pin printers, this is achieved in two passes;
- Draft– Fastest draft printing
The quality of dot matrix printing depends on the number of pins in the print head: more pins = more dots. Therefore, only 24-pin printers can provide high quality LQ (Eng. Letter Quality - the quality of a typewriter). The print speed in LQ mode is, of course, much slower than in standard and draft mode. Therefore, 9-pin and line matrix printers are an order of magnitude faster.
High or medium quality can be the machine's standard, and draft printing is available as an optional mode. At the same time, 24-pin printers support all three modes, prompting the user to choose the appropriate print quality on their own.
If at this particular moment it is important to you maximum speed printing, and quality is not important, feel free to choose draft mode to get a document in record time. Interestingly, in draft mode, line matrix printers can print two lines of the future image at once.
conclusions
If you are thinking about buying a dot matrix printer, you should once again weigh all the advantages and disadvantages of dot matrix technology.
Among the disadvantages: increased noise level during operation and low adaptability for printing complex images, such as drawings and photographs. Some printers have a noise reduction mode, but when using this mode, the print speed may drop noticeably.
At the same time, if you are going to use dot matrix printers for their intended purpose - for printing forms, tickets, checks and technical reporting at the enterprise - the above disadvantages are not so critical. These are the limitations that you should keep in mind in order to rationally distribute the load on the equipment.
Dot matrix printers have many advantages and, what is especially important, in many aspects these devices are noticeably superior to laser and inkjet ones.
Dot matrix printers are still indispensable in situations where you need low-cost streaming printing, the ability to create several absolutely identical copies of a document at the same time, printing on continuous ribbons or multi-layer forms.
Matrix printers are indispensable for automatic output of text information from measuring or computing devices in production.
Wherever speed, reliability and low cost of printing are important, but high demands are not placed on the quality of the print, a dot matrix printer will be the best option.
One of the key dot matrix printer benefits- its high fault tolerance and slow wear of resource parts. For example, the print head life of an average dot matrix printer can reach 30 million characters. And the resource of the entire printer is about 10 million lines.
Dot matrix printers do not require complex maintenance and are easy to operate. Cartridges for OKI and Epson dot matrix printers are easy to replace - their design prevents ink from getting on your hands or clothes.
Additionally, the use of inexpensive consumables, including cheap folded and roll paper for dot matrix printers, will help save on printing huge volumes of text.
Finally, for all its economy, the dot matrix printer creates the most durable prints that cannot be completely washed off, since the imprint of the needles remains on the paper anyway. This allows you to more securely fix the text and makes it difficult to falsify financial documents.
In our store you can buy OKI and Epson dot matrix printers. Contact our consultants and they will definitely help you find optimal model for your tasks.
