Dot Matrix Printers - A Brief Overview
Dot matrix printers are full-featured desktop printer that use a series of pins to create a printed image. They have been in use since the 1970s and continue to be popular due to their low cost, excellent printing quality, and versatile range of applications.
Unlike inkjet or laser printers, dot matrix printers operate on a different principle. Instead of using heated or charged toner, they rely on a set of tiny pins that move up and down to strike an inked ribbon, creating an image on the paper. Each pin is connected to an individual column of pixels and by moving the pins in succession, the printer can create a printed page. This same mechanism is also used in typewriters and cash registers.
The main benefit of dot matrix printers is the versatility of their output. Unlike inkjet or laser printers, which print mainly text, dot matrix printers can print images as well, giving them a wide range of potential applications. They are often used to produce business forms, tickets, receipts, labels and checks. Dot matrix printers are also more robust than most people think, and can easily handle large volumes of printing without significant wear and tear.
When compared to other types of printers, dot matrix printers are usually less expensive and more reliable. The cost of consumables such as ribbons, paper, and ink can also be kept low. However, since their technology is now quite dated, their speed and print quality is generally inferior to newer models. Additionally, they tend to be quite loud when printing, making them unsuitable for home use.
Despite their drawbacks, dot matrix printers remain popular and have a variety of uses. They are commonly used in businesses and industries where reliability and speed are not paramount, but cheap and consistent printing is required. Many organizations find that having a reliable and low-cost printer is far more valuable than investing in a faster and more modern model.
