I've been using this printer with my macs for over a year now with few issues. I just tried to set it up wirelessly using my AirPort Express and when I go into printer setup, it spits back a message that says "drivers are not available at this time, please contact the manufacturer" so I went and downloaded the drivers from Canon. Still not working. Where are drivers stored in the Library so I can manually select the software I want to use? I found a driver in Library->Printers but when I select it, it still looks for the driver online and tries to download it, so I get the same message. HELP!!!
