Aarrgghh!
I am trying to print from the photo tray and have tried EVERYTHING, including shutting down the printer, to print a photo on photo paper that is A4 sized (4.25 x 5.5). Set the paper size to A4 and it printed a photo out letter sized! Tried custom and get paper mismatch error. Tried a bunch of other stuff, too. Please help...this is sooooooo annoying.
I am working on a MacBook Pro OS X 10.9.1.
