Ok, I am stumped, maybe because I am a newbie to setting up a wireless network. I am using an Airport Express hardwired to my DSL modem. It works well with both my MacBook Pro and a Dell desktop PC. Have now connected my Dell P1500 printer to the AE via a usb cable. I am stumped as to how to set this up so that I can print with either computer. Any help would be sorely appreciated. Thanks in advance.
