Connectivity
The USB (Universal Serial Bus) is truly universal--all printers have either a USB 1.1 or the newer, faster USB 2.0 port. Don't worry too much if your system doesn't have USB 2.0--the two standards get along just fine, and USB 1.1 is fast enough for printing. Mac users can instead opt for FireWire (IEEE 1394) on some models. But if you want to go old school, you'll still find plenty of printers that accept those big, 25-pin parallel cables. Workgroup printers also support printing over a network using a standard Ethernet cable with an RJ-45 connector. For even better mobility, many models support printing wirelessly, using infrared, Bluetooth, and Wi-Fi access points with built-in print servers
