Dot matrix printer

printer which prints graphics and text by pressing pins against an inked ribbon

A dot matrix printer or impact matrix printer refers to a type of computer printer with a print head that runs back and forth on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like a typewriter. 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. Because the printing involves mechanical pressure, these printers can create carbon copies and carbonless copies.

<hardware, printer> A kind of printer with a vertical column of up to 48 small closely packed needles or "pins" each of which can be individually forced forward to press an ink ribbon against the paper. The print head is repeatedly scanned across the page and different combinations of needles activated at each point.
Dot matrix printers are noisy compared to non-impact printers.
