I bit the bullet, and bought the Airport Extreme with the Modem, External Antenne(sp?), and USB Printer port. I thought it would be cool to be able to put my HP Deskjet 5550 on my network and share it between my TiPB, and two PC Desktops. I for the life of me can't figure out how to make the PCs recoginize the printer on the network. Any ideas?
