Dot matrix printing Wikipedia. Typical output from a dot matrix printer operating in draft mode. This entire image represents an area of printer output approximately 4. Dot matrix printing or impact matrix printing is a type of computer printing which uses a print head that moves back and forth, or in an up and down motion, on the page and prints by impact, striking an ink soaked cloth ribbon against the paper, much like the print mechanism on a typewriter. However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced. Each dot is produced by a tiny metal rod, also called a wire or pin, which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers pawls. Facing the ribbon and the paper is a small guide plate named ribbon mask holder or protector, sometimes also called butterfly for its typical shape. It is pierced with holes to serve as guides for the pins. This plate may be made of hard plastic or an artificial jewel such as sapphire or ruby. The portion of the printer containing the pins is called the print head. When running the printer, it generally prints one line of text at a time. There are two approaches to achieve this Epson VP 5.

Wide carriage printers were often used by businesses, to print accounting records on 1. They were also called 1. The common serial dot matrix printers use a horizontally moving print head.

Dot matrix printing or impact matrix printing is a type of computer printing which uses a print head that moves backandforth, or in an upanddown motion, on the. PhenQ-label_160x45_13-1.jpg' alt='Printhead Installed Not Intended Use Statement' title='Printhead Installed Not Intended Use Statement' />The print head can be thought of featuring a single vertical column of seven or more pins approximately the height of a character box. In reality, the pins are arranged in up to four vertically orand horizontally slightly displaced columns in order to increase the dot density and print speed through interleaving without causing the pins to jam. Thereby, up to 4. In a considerably different configuration, so called line dot matrix printers use a fixed print head almost as wide as the paper path utilizing a horizontal line of thousands of pins for printing. Sometimes two horizontally slightly displaced rows are used to improve the effective dot density through interleaving. While still line oriented, these printers for the professional heavy duty market effectively print a whole line at once while the paper moves forward below the print head. The printing speed of serial dot matrix printers with moving heads varies from 3. In contrast to this, line matrix printers are capable of printing much more than 1. Because the printing involves mechanical pressure, both of these types of printers can create carbon copies and carbonless copies. Print head of a used 9 pin printer Star NL1. These machines can be highly durable. When they do wear out, it is generally due to ink invading the guide plate of the print head, causing grit to adhere to it this grit slowly causes the channels in the guide plate to wear from circles into ovals or slots, providing less and less accurate guidance to the printing wires. Eventually, even with tungsten blocks and titanium pawls, the printing becomes too unclear to read, a common problem when users failed to maintain the printer with regular cleaning as outlined in most user manuals. A variation on the dot matrix printer was the cross hammer dot printer, patented by Seikosha in 1. HTB1M0xrIpXXXXXfaXXXq6xXFXXXU/100-Original-New-Printer-Print-Head-For-Canon-QY6-0055-i9900-i9950-iP8500-Printhead-On-Sale.jpg' alt='Printhead Installed Not Intended Use Statement' title='Printhead Installed Not Intended Use Statement' />The smooth cylindrical roller of a conventional printer was replaced by a spinning, fluted cylinder. The print head was a simple hammer, with a vertical projecting edge, operated by an electromagnet. LC40_46_52_60LE830U.pdf-3.png' alt='Printhead Installed Not Intended Use Statement' title='Printhead Installed Not Intended Use Statement' />Where the vertical edge of the hammer intersected the horizontal flute of the cylinder, compressing the paper and ribbon between them, a single dot was marked on the paper. Characters were built up of multiple dots. Although nearly all inkjet, thermal, and laser printers also print closely spaced dots rather than continuous lines or characters, it is not customary to call them dot matrix printers. Early historyeditIn 1. Rudolf Hell invented the Hellschreiber, an early facsimile like dot matrix based teletypewriter device,4 patented in 1. Between 1. 95. 2 and 1. Fritz Karl Preikschat filed five patent applications567 for his teletype writer 7 stylus 3. PKT printer,4 a dot matrix teletypewriter built between 1. Germany. 7 Like the earlier Hellschreiber, it still used electromechanical means of coding and decoding, but it used a start stop method asynchronous transmission rather than synchronous transmission for communication. In 1. Telefonbau und Normalzeit Gmb. H Tu. N, later called Tenovis, the device was introduced to the Deutsche Bundespost German Post Office, which did not show interest. When Preikschat emigrated into the USA in 1. USA to Tu. N. 7 The prototype was also shown to General Mills in 1. An improved transistorized design4 became the basis for a portable dot matrix facsimile machine, which was prototyped and evaluated for military use by Boeing around 1. Various sources indicate that IBM introduced the first dot matrix printer in 1. In 1. 96. 8, the Japanese manufacturer OKI introduced its first serial impact dot matrix printer SIDM, the OKI Wiredot. The printer supported a character generator for 1. It was aimed at governmental, financial, scientific and educational markets. For this achievement, OKI received an award from the Information Processing Society of Japan IPSJ in 2. The DECwriter LA3. Digital Equipment Corporation DEC of Maynard, Massachusetts. It printed 8. 0 columns of uppercase only 75 dot matrix characters across a unique sized paper. The printhead was driven by a stepper motor and the paper was advanced by a noisy solenoidratchet drive. The LA3. 0 was available with both a parallel interface LA3. P and a serial interface LA3. S however, the serial LA3. In 1. 97. 2, a receive only variation named LA3. A became available as well. The LA3. 0 was followed in 1. LA3. 6, which achieved far greater commercial success, becoming for a time the standard dot matrix computer terminal. The LA3. 6 used the same print head as the LA3. The carriage was moved by a much more capable servo drive using a DC electric motor and an optical encoder tachometer. The paper was moved by a stepper motor. The LA3. 6 was only available with a serial interface but unlike the earlier LA3. This was possible because, while the printer never communicated at faster than 3. During the carriage return period, characters were buffered for subsequent printing at full speed during a catch up period. The two tone buzz produced by 6. LA3. 6 quickly copied by many other manufacturers well into the 1. Most efficient dot matrix printers used this buffering technique. Digital then broadened the basic LA3. LA1. 80 1. 80 cs line printer. LS1. 20 1. 20 cs terminal. LA1. 20 1. 80 cs advanced terminal. LA3. 4 Cost reduced terminal. LA3. 8 An LA3. 4 with more features. LA1. 2 A portable terminal. In 1. 97. 0, Centronics then of Hudson, New Hampshire introduced a dot matrix printer, the Centronics 1. The search for a reliable printer mechanism led it to develop a relationship with Brother Industries, Ltd of Japan, and the sale of Centronics badged Brother printer mechanisms equipped with a Centronics print head and Centronics electronics. Unlike Digital, Centronics concentrated on the low end line printer marketplace with their distinctive units.
