Printer Resources
The end user of a computer requires the printouts of the documents and graphics he has designed on the computer. The peripheral which converts the electronically stored information into hardcopies of readable texts and pictures on the paper or transparency is called the printer. As you buy printers you find that they are available in either black/white or color versions at competitive rates depending on the quality of output required. It is possible to print documents on local printers connected to the desktop computers using a printer cable.
Quality printouts of information from the internet can be taken in latest models of printers which have network interfaces in-built or the wireless mode. Some advanced printers can be directly interfaced to scanners and digital cameras. Many other printers can do the function of photocopier by combining with scanners and fax machines.
The person interested in printing text material buy printer of dot-matrix type. A bunch of closely fixed pins impinge through a ribbon, letters and recognizable characters on to the paper. The latest dot-matrix printer can print up to 600 characters per second. The closer and the finer the pins are (numbering 24), the better the quality of the image printed. Dot-matrix printers find use in departmental stores and warehouses where invoices, purchase orders and labels with multiple carbon copies are required. The price of HP Dot-matrix printer ranges from US$400 to US$800.
Inkjet printer is a device that is used by people who work in artistic and photographic fields. It contains magnetic plates which direct a spray of ionized micro drops of ink on the paper to create a definite pattern or character.

A photographer wanting to buy printers chooses the dye sublimation type for high quality graphics and photographic outputs.
