    Thanks! This just fixed my problem. Using Canon iP90 and 10.6.2 error 306. My picture would print about 1/2 before it stopped.

    Didn't work for me. After I deleted the printer I couldn't add it back. When I click the + the printer is nowhere to be seen.

    ^ Using your Install DVD, Install printer drivers from the optional installer: http://support.apple.com/kb/HT3415

    My problem was slightly different, my computer had created a “double” of my printer, so when the printer received its order to print, it was no longer recognized. I merely threw away the “double” and now everything works just fine. Thanks!

      Make sure it is connected correctly. Also, reinstall the printer from the CD or by finding the latest drivers on the Canon website.

    Have done this at least 5 times. Works for about 15 mins. What’s crazy is the other computer in the room is an Acer and NEVER loses the connection. WHY, APPLE, WHY?

    Spent a long time with Apple support on this. Canon PIXMA Pro9000 fails with error code 306 when connected via Airport Express. Deleting/adding the printer works for a while, but then always see the same 306 failure again. Apple said this is a Canon problem, so I contacted Canon, who told me that the Pro9000 is not guaranteed to work when connected via wifi, only a direct USB connection will work. So much for this expensive printer and convenience.

    Hi, I have the same problem, tried this solution and it still comes up with error 306.

    I’m trying to connect a canon printer MP280 to a mac (OSX 10.7.5) though a PC (windows 7). I can find the printer on my mac and connect it, but when i try to print it comes up with support code: 306. Is there anything else that you can suggest that i try?
    Thankyou

    It worked even though the lock wasn’t engaged. Just want to inform those that think it might not work if they see an unlocked pad lock on the screen to go ahead and delete the printer and then add it. It worked for me.
