The all-in-one printer is both an input and output device, combing the functions of multiple devices into one unit. These usually are an optical scanner, copy machine, fax machine and printer. The unit is connected to a single computer or may be part of a wired or wireless computer network, permitting multiple computers to access its functions. The scanner portion of the device enables documents or images to be converted into digital formats for storage or use on the computer or network. The all-in-one unit usually includes software that must be installed on the computer, or it may integrate with other specialized third-party software designed to handle images and scanned text. The copy machine function uses the scanner input bed to electronically scan a document and print duplicate copies. The facsimile (fax machine) functions of the device enable scanned documents to be sent to remote devices or locations telephonically or via an Internet connection. The two primary types of output for all-in-one printers are ink jet and laser. Ink jet printers usually output pages at a slower rate and may have lower image quality than laser printers. Regardless of your choice of ink jet or laser printer, Kelkoo will lead you to a quality printer at the lowest price around from such manufacturers as Kodak, Canon, Epson, HP and more!
