A hammer presses the wheel against a ribbon, that successively makes associate degree ink stain within the form of the character on the paper.Daisy-wheel printers turn out letter-quality print however cannot print graphics.
dot-matrix: Creates characters by placing pins against associate degree ink ribbon. every pin makes a dot, and combos of dots type characters and illustrations.
ink-jet: Sprays ink at a sheet of paper. dot matrix printer printers turn out high-quality text and graphics.
laser: Uses identical technology as copy machines. optical device printers turn out terribly top quality text and graphics.
LCD & crystal rectifier :Similar to a electrostatic printer, however uses liquid crystals or light-emitting diodes instead of a optical device to supply a picture on the drum.
line printer: Contains a series of characters or pins that print a complete line at just the once. Line printers area unit in no time, however turn out low-quality print.

Printer Characteristics

Printers are classified by the subsequent characteristics:
quality of type: The output made by printers is alleged to be either letter quality (as sensible as a typewriter), close to letter quality, or draft quality. solely daisy-wheel, ink-jet, and optical device printers turn out letter-quality sort.

speed: Measured in characters per second (cps) or pages per minute (ppm), the speed of printers varies wide. Daisy-wheel printers tend to be the slowest, printing regarding thirty cycle per second.

Dot-matrix printers will print up to five hundred cycle per second, and optical device printers vary from regarding four to twenty text pages per minute.
impact or non-impact: Impact printers embrace all printers that job by placing associate degree ink ribbon. Daisy-wheel, dot-matrix, and line printers area unit impact printers. Non-impact printers embrace optical device printers and dot matrix printer printers. The vital distinction between impact and non-impact printers is that impact printers area unit abundant noisier.
graphics:Some printers (daisy-wheel and line printers) will print solely text. alternative printers will print each text and graphics.
fonts : Some printers, notably dot-matrix printers, area unit restricted to 1 or a number of fonts.
