I have a classroom with a dozen G5 Mac Pros running Tiger and we want to allow them to use a couple of A3 photo-quality inkjet printers and a couple of flatbed scanners. I see that the airport base station extreme only has one usb port. Is it possible to use one airport extreme base station to connect all of these peripherals, add airport cards to each Mac Pro, and be able to use any of the printers or scanners from any of the Macs? What other equipment is necessary? Should we look to buy any specific printers or scanners that will be more compatible? Is there some other approach that will work better? Thanks for any advice.
