COMPUTER FUNDAMENTALS

Detailed explanation-1: -Dot matrix printing, sometimes called impact 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.

Detailed explanation-2: -An impact printer is a type of printer that works by direct contact of an ink ribbon with paper. A metal or plastic head strikes the ink ribbon, whereby the ribbon is pressed against the paper and the desired character (letter, digit, dot, line) impression is printed on the sheet.

Detailed explanation-3: -Dot matrix printers can print multiple sheets at once, printing directly onto the white front sheet, then following on to the coloured carbon copies behind. In general, dot matrix printers are more reliable than laser or inkjet machines, especially when used in dirty environments such as warehouses or car garages.

Detailed explanation-4: -A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper.
