Like AirPort Express, the current AirPort Extreme base station can be used to share attached USB printers. The process is even easier than sharing a hard drive. Simply attach the printer, and the base station makes it available. Computers can locate and access the printer via Bonjour. You can elect to set up the printer using Mac OS X’s Printer Setup Utility or choose it from the Print dialog box’s Printer menu (you’ll find it in the Bon Jour Printers submenu). Windows computers can locate and use printers via Apple’s Bonjour for Windows.
As with shared hard drives, you can also elect to share the printer over the base station’s WAN port, and the base station can support multiple printers through the use of a USB hub. A mix of shared printers and hard drives is also supported when using a USB hub.
