Hi: People often post of wireless printing via Time Capsule, Airport Extreme Basestation's USB hookup & Airport Express. What about all those 'all-in-one' printer/fax/scanner/copier devices out there? Brother, HP, Canon, etc...? Can those be hooked up the same way, or by buying a Bluetooth or wireless USB adapter or some such, or is 'wireless printing' ONLY about printing so far. Thanks. Richard.
