Most manufacturers offer an all-in-one printer that also features a fax machine, copier, and scanner. By purchasing a multifunction printer, it could save the cost of having to buy one or more of these other machines separately. These all-in-one printers have been nicknamed the Swiss Army knife of printers, because they combine several essential business machines into one. In most models, you’ll find not only a printer, but also a fax machine, copier, and scanner, so for homes and smaller businesses, an MFP may be the most economical choice. The most common models feature a flatbed scanner and are available as either a laser or inkjet. Many models feature USB and Wi-Fi connectivity, as well as memory card bays, auto-duplexers for printing on two sides, and auto feeders for scanning of multi-page documents.
