A printer is one of the output devices of a computer for printing the results of computer processing on a related medium. The indexes for measuring the quality of the printer have three items: print resolution, print speed, and noise. Printers are of various types, and impact printers and non-impact printers are classified according to whether or not a printing element has an impact on paper. According to the character printing structure, the character printer is divided into a full-character printer and a dot matrix character printer. A serial printer and a line printer are separated in such a manner that a line of characters is formed on paper. According to the adopted technology, the printer is a printer of column type, sphere type, ink-jet type, thermosensitive type, laser type, electrostatic type, magnetic type, light-emitting diode type and the like.
