Many all-in-one printers allow you to make black-and- white photocopies as well as color photocopies. ? Some all-in-one printers include a sheet fed scanner, which scans single sheets of paper. Other all-in-one printers include a flatbed scanner, which allows you to place thick items you want to scan on a flat surface.

? If you want to use an all-in- one printer as a standalone fax machine, look for a complete set of fax controls on the printer so you can send and receive faxes when your computer is turned off.

? You can buy all-in-one printers in inkjet or laser printer format.

Most laser printers come with Printer Control Language (PCL). A page printed on a PCL printer may look different when printed on another laser printer.
