The MFC-J430w prints from, scans to, and faxes from a PC, and it works as a standalone copier and fax machine. It also offers a 20-page automatic document feeder(ADF) to supplement the letter-size flatbed, so you can scan multipage documents and legal-size paper. What you won’t find are photocentric features, like memory card slots or PictBridge support for printing from cameras.
The printer doesn’t offer wired network support, but it does support WiFi, which will let you share it in a micro office or at home. Outside of the dual role of home and home-office printer, however, it’s best suited as a strictly personal printer because of its limited paper handling, with a 100-sheet tray, no duplexer, and no paper handling options.
