I've managed to get printing to a USB printer working even though USB support isn't yet available. It worked with Beta 1 yesterday and with Beta 2 today. My guest OS is Windows XP Home SP2. The printer (in my case an HP Deskjet 970Cxi) has to be connected to the Airport Extreme / Express base station's USB port. Then you simply follow the instructions which can be found at http://www.ifelix.co.uk/tech/1004.html This requires one to add a printer in Windows, and to create a TCP/IP port for it that points to the IP address of the Airport base station. Check that the port is sending raw data to the printer port and you're done. Incidentally, with Beta 1 it is possible to use an Ethernet to wireless bridge, such as the Netgear ME101, to connect to a wireless network,. I see now that Airport support has been added to Beta 2 it won't be needed any more. Thanks for a superb product - I shall definitely be putting in a pre-order. Steve
