[0002] A printer is a computer output device used to print computer processing results onto a suitable medium. Three indicators measure the quality of a printer: print resolution, print speed, and noise. There are many types of printers. Depending on whether the printing element strikes the paper, they are categorized as impact printers and non-impact printers. Based on the structure of printed characters, they are categorized as full-width printers and dot-matrix printers. Based on how a line of text is formed on paper, they are categorized as serial printers and line printers. Based on the technology used, printers can be categorized as cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and LED printers.
