A list of printer reviews by editors and users.
"Whether you prefer the term multi-function printer (MFP), all-in-on (AIO), or some other variation on the name (multi-function copier, or MFC, is still around), printers that do more than just print have some clear advantages over their single-function brethren; namely, they save space and money compared to buying multiple separate machines. And who doesn't like saving space or money?
If you're looking for an office MFP, one of the printers included here may well be the right one. This roundup includes color and mono printers, inkjets and lasers, and different levels of paper handling that run the range from suitable for a home office to suitable for a small to medium size office or workgroup. Each is an Editors' Choice in its own category. There's a good chance that one of them is your best choice as well."
"Two new printers debut on the chart. Epson's Expression Premium XP-800 is a fully featured, photo-oriented model with CD/DVD printing and great output quality. Brother's Business Smart MFC-J4510DW has an innovative design that makes it faster and more versatile."
