My Canon MX340 is currently connected via USB to my AirPort Time Capsule. It was not working at first, but I reinstalled the drivers on each computer (There are five total, 4 of them Macs, 1 of them a PC) and it seemed to work, even on the PC. It was working for a couple days and now it is back to not working. When I try to connect on one of the Macs via AirPort, the printer does not show up at all (yes, it is plugged into the AirPort device). I read that you have to manually connect the printer to the computer via USB, but that is not an option as I cannot drag the printer to five different computer stations. I reset the printer options in preferences (Mac) and when I go to add the printer again, it still does not show up. I tried turning the printer on and off, unplugging it, etc. Someone PLEASE tell me how to wirelessly connect all computers (including the PC) to the printer, via AirPort/Bonjour, and have it STAY connected.
