Question

What is Dot matrix printer ??​

Answer 1

Answer:

Impact Dot 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.

Answer 2

Answer:

A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. In contrast, inkjet and laser printers technically exhibit dot matrix printing, but they are not considered "dot matrix printers".

Impact vs. non-impact is one way in which printers are divided into two classes. Dot-matrix impact printers, "the most common type still sold as of October of 2012," use "a vertical column of pins which fire" (and thus force contact between the paper and "an ink-soaked ribbon").
