Printers for small and medium-sized companies have a faster print speed of at least 20 pages per minute, and a paper capacity of at least 200 pages. That makes them suitable for SME and you don't have to wait long before bills, notes, and spreadsheets come out of your printer. In addition to WiFi, most printers also have a network port to remotely control your printer and send print jobs from wired devices. If you also want to scan, copy, and fax, you should get an all-in-one printer.
