Detailed explanation-1: -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.
Detailed explanation-2: -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.
Detailed explanation-3: -Ribbon ink is most often used with dot matrix printers and thermal transfer printers. With impact and dot matrix printers, an ink-soaked ribbon is pressed against the page to print.
Detailed explanation-4: -Because dot matrix printers use an impact printhead that strikes the paper surface, they provide a time-tested means of generating multi-part forms on paper coated with micro-encapsulated ink on its reverse side, or sandwiched with carbon paper.
