What is Printer?

• A printer is an output device thatproduces text and graphics on aphysical medium such as paper.

• There are two types of Printers.• Impact Printers • Non Impact Printers

Types of Printers

• Impact Printers:• An impact printer forms characters and

graphics on a piece of paper by striking a mechanism against an inked ribbon that physically contacts to the paper.

Further types of Impact Printers

• Dot-Matrix Printers• Daisy-wheel Printers• Line printers

Dot-Matrix Printers

• The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce patterns of dots on the paper to form the individual characters.

Daisy-wheel Printers

• It uses a metal or plastic disk containing each of the letters, numbers, and other characters. When something is printed, the printer rotates the disk to each character and then using a hammer strike each character into an ink ribbon to create the character on paper.

Line Printer

• A high-speed Printer capable of printing an entire line at one time. A fast line printer can print as many as 3,000 lines per minute.

Non-Impact Printer

• A type printer that does not operate by striking a head against a ribbon.

• These are further types of Non-Impact printer:• Ink-Jet printer• Photo printer• LASER printer• Thermal printer• Mobile printer

Ink-Jet printer

• A type of printer that works by spraying ionized ink at a sheet of paper.

• A typical Ink-Jet printer provides a resolution of 300 dots per inch.

Photo printer

• A printer specialized for smaller prints.• Introduced in the mid 1990s.• Photo printer used dye sublimation for

high quality printing on Physical media.

LASER printer

• A LASER printer is a printer that uses a focused beam of light to transfer a text and images onto paper.

• LASER printer uses LASER technology for printing on paper.

Thermal printer

• A printer that uses heat to register an impression on paper.

• Thermal printer is a digital printing process.

• It uses coated papers for printer.

Mobile printer

• Mobile printing is the process of sending data to a printer wirelessly from a smartphone or a tablet.

• Mobile printer is a small printer that uses small battery and attached to the PDAs, smartphones and Note book

MFP (Multifunction Peripheral Device)

• A multifunction peripheral is asingle device that looks like a copymachine but provides the functionality of a printer, scanner, copy machine, and perhaps a fax machine (Figure).

Summary/ Conclusion

• We discussed about printers its types like impact and non-impact printer and the further types.

• The explanations of the further types.• The working of the printer.• We discussed about MFP.
