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
Cyanotype, also referred to as "blueprinting", is the oldest non-silver photographic printing process. [1] It involves exposing materials which have been treated with a solution of potassium ferricyanide and ferric ammonium citrate to a UV light source such as the sun. Negative or positive images can be obtained by blocking UV light from ...

The term dot matrix printer is used for impact printers that use a matrix of small pins to transfer ink to the page. [17] The advantage of dot matrix over other impact printers is that they can produce graphical images in addition to text; however the text is generally of poorer quality than impact printers that use letterforms (type).
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]
Near letter-quality is a form of impact dot matrix printing. What The New York Times called "dot-matrix impact printing", [2] was deemed almost good enough to be used in a business letter [5] Reviews in the later 1980s ranged from "good but not great" [6] to "endowed with a simulated typewriter-like quality".
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.
