A Comprehensive Guide to Dot Matrix Printers
A Dot matrix printer, also popularly known as an impact matrix printer, can produce various fonts and arbitrary graphics. With mechanical pressure, it strikes an ink-soaked fabric ribbon against the paper as it moves back and forth across the page and prints an impression on the paper.
Features of Dot Matrix Printers:
A] Print Quality: The number of pins that print the dots can range anywhere between 9 and 24. The best dot-matrix printers (24 pins) can create type that is nearly letter-quality, though there is still a difference if you look closely.
B] Speed: The speed, measured in characters per second (cps), can range from roughly 50 to over 500 cps. Most dot-matrix printers have varying print speeds based on the print quality.
Types of Dot Matrix Printers:
Following are the types of dot matrix printers that are available in the market:
1. Serial Dot Matrix Printers: These printers communicate with a computer or other devices via a serial interface, such as RS-232. They are typically seen in industrial settings and are capable of printing multiple copies of forms, invoices, and other documents.
2. Parallel Dot Matrix Printers: To communicate with a computer, these printers use a parallel interface, commonly a centronics interface. They are popular in workplaces, retail stores, and other corporate environments due to their rapid printing capabilities.
3. USB Dot Matrix Printers: These printers connect to a computer or other devices via a USB (Universal Serial Bus) interface. USB dot matrix printers offer improved compatibility and convenience, as USB ports are prevalent on modern computers and laptops.
4. Network Dot Matrix Printers: These printers have built-in networking capabilities, allowing them to be connected directly to a local area network (LAN) or the internet. Network dot matrix printers are commonly used in offices and shared work environments where multiple users need access to a single printer.
5. Wireless Dot Matrix Printers: These printers have built-in networking capabilities, allowing them to be directly connected to a LAN or the internet. Dot matrix network printers are often used in workplaces and shared work environments where several users require access to a single printer.
6. Portable Dot Matrix Printers: These compact printers are designed for portability and can be easily carried or transported. They are commonly used by field service personnel, delivery drivers, and other professionals who require on-the-go printing capabilities.
7. Multifunction Dot Matrix Printers: These printers combine dot matrix printing with additional functionalities such as scanning, copying, and faxing. They serve as all-in-one devices, providing multiple office-related functions in a single machine.
Dot matrix printers are used for specific applications where their durability, multipart form printing, and low-cost consumables are advantageous.
Printing Process in Dot Matrix Printer:
i) In the first step of the dot matrix printer working, the printer receives a series of ASCII codes from the computer that is initially saved in the RAM buffer.
ii) The bitmap table in the printer's ROM chip instructs the printer on the pattern of dots to be used to form the desired character shape represented by the ASCII code.
iii) The printer processor reads the dot pattern data from the bitmap table and sends it to the printer head.
iv) The printer head has 9, 18, or 24 vertically aligned pins, with one end of each pin attached to an individual electromagnet.
v) This electromagnet is energised to fire the print pins against the ribbon and paper, causing the moving pin to impact the ink-coated ribbon.
vi) The electromagnet is de-energized once the pin fires, causing the spring to pull the print pin back.

Advantages of Using Dot Matrix Printers:
a) Maximum output: Thanks to its potential to operate with multi-part stationery, it is perfect for heavy-duty printing at inexpensive prices.
b) Reliability: the dot matrix printer has a robust build quality while giving a steady performance.
c) Value for money: Impact dot matrix printer price is one of the lowest per-page printing expenses when compared to others. The ink ribbon does not dry out quickly, which again runs longer and saves you from making a quick purchase. They can use continuous paper instead of individual sheets.
Points to keep in mind before purchasing Dot Matrix Printers
