OK, I bought a Canon MP970 printer and hooked it up to the airport extreme, changed all of the ports to 10.0.1.1 on my XP, shared the printer, ran Bonjour, ran airport utility, and everything I know how to do. I can print from my Powerbook G4 and from a new black macbook that I just bought on my network. Problem is I cannot print from my windows XP PC. Very frustrating. It did work fine with my HP printer; that is print from my laptops AND my PC desktop. Any help would be greatly appreciated!
