Dot matrix printing or
impact matrix printing is a type of
computer printing
which uses a print head that runs 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.
