I've installed 10.6.5 on a test Mac to test out Airprint and it works fine. I've installed iTunes 10.1 on Windows and the printer does show up on my iPad, but it has a lock next to it and asks me for a password every time I print. Seems like it's looking for a local admin password. I'm not especially proficient in Windows... how do I set the printer to print without requiring a password? I've tried allowing guests to print, giving the everyone group full access, but it still asks me for a password.
