A printer that prints without banging a ribbon onto paper. Laser, LED, inkjet, solid ink, thermal wax transfer and dye sublimation printers are examples of non-impact printers. Common examples of impact printers include dot matrix, daisy-wheel printers, and ball printers. Dot matrix printers work by striking a grid of pins against a ribbon. ...
