I was reading on CNET that this was possible with the express and I had been trying to do this with my Airport extreme without any success, im pretty sure the extreme doesnt do it.
Thanks guys
I wanted to set my airport up to print from work to my home 20 miles away.... my original workaround was going out and purchase a "wireless usb print server". I then ran across info on CNET that states the Express is a wireless USB print server.
Am I missing something?
