The following are two distinct categories of printers:
Impact printer: It establishes a mechanical contact between the print head and the paper. There are various types of impact printers, such as line printers, drum printers, and dot-matrix printers.
Non-impact printer: It does not establish any mechanical contact between the print head and the paper. This printer was introduced to overcome the low speed and high cost of impact printers. The well- known non-impact printers are inkjet and laser printers.
