Dot matrix printing, sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers typically use 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 or line printer.

Wikipedia

Dot matrix

A dot matrix is a 2-dimensional patterned array, used to represent characters, symbols and images. Most types of modern technology use dot matrices for display of information, including mobile phones, televisions, and printers. The system is also used in textiles with sewing, knitting and weaving.

An alternate form of information display using lines and curves is known as a vector display, was used with early computing devices such as air traffic control radar displays and pen-based plotters but is no longer used. Electronic vector displays were typically monochrome only, and either leave the interiors of closed vector shapes unfilled, or perform slow, time-consuming and often non-uniform shape-filling, as on pen-based plotters.

In printers, the dots are usually the darkened areas of the paper. In displays, the dots may light up, as in an LED, CRT, or plasma display, or darken, as in an LCD.

Examples of use of dot matrix
1. A dot–matrix indicator in a bus shelter said No. 15 to Blackwall÷ 3 mins but for all we knew it might have said that for hours, and still be saying it at the crack of doom.
2. Four dot–matrix signs read "Please wait for train information" and "No smoking". Below a tube map, the four groups of relatives who visited laid four bouquets of flowers, including lilies, gladioli and sunflowers, with personal messages and a photograph of one of the victims.
