Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and 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. They were also known as serial dot matrix printers. [4]
Impact printers create an image by using some mechanism to physically press an inked ribbon against the page, causing the ink to be deposited on the page in the shape desired. These printers are typically loud, but remain in use today because of their unique ability to function with multipart forms.
Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor [1] at Diablo Data Systems.It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster.
The IBM 4245 is a high-speed impact printer that uses an engraved band. IBM proposed it as a replacement for the 1403, 3203 and the 3211/3811. As an example the Montana Department of Administration bought three 4245s (a model 12 and two model 20s) in October 1985 to replace two IBM 1403s and a 3211/3811.
Dot matrix printers are still commonly used in low-cost, low-quality applications such as cash registers, or in demanding, very high volume applications like invoice printing. Impact printing, unlike laser printing, allows the pressure of the print head to be applied to a stack of two or more forms to print multi-part documents such as sales ...

Many impact printers, such as the daisywheel printer and dot matrix printer, used a print head that printed a character then moved on until an entire line was printed. Line printers were much faster, [4] as each impact printed an entire line. There have been five principal designs: Drum printers; Chain (train) printers; Bar printers; Comb printers
