Computer Peripherals: Printers

A printer is a computer peripheral which produces a text or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies.

Most printers are basically used as local peripherals, and are attached by a printer cable or a USB cable to a computer which serves as a document source. Network printers have built-in network interfaces, typically wireless or Ethernet based, and can serve as a hard copy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.

A few modern printers can directly interface to electronic media such as memory cards, or to image capture devices such as digital cameras and scanners; some printers are combined with scanners or fax machines in a single unit, and can function as photocopiers.

Printers that include non-printing features are sometimes called multifunction printers (MFP), multi-function devices (MFD), or all-in-one (AIO) printers. Most MFPs include printing, scanning, and copying among their many features.

Printers are differentiated by the printing technology used. The types of printers presently available are: Toner-based, Liquid Inkjet, Solid Ink and Dye-Sublimation. The inkless printers include Laser printers,Thermal Printers and UV printers.
