That would probably be within the settings on the printer itself, check the manual for the printer. You can also try removing the tray, some printers will auto select the next available tray.

Thanks. Nothing in the manual about this. I just contacted Canon support and I'll see what they have to say.

I'm having the same issue with a Canon MX892. I'll do some research and get back to the discussion group.

Found out that iOS AirPrint is an app by app situation. Apple's Photo App will default to 4x6 and will require that you print using the rear tray. I have an MX892 and found this to be true. Here's a quick PDF from Canon's web site: http://www.usa.canon.com/CUSA/assets/app/pdf/airprint/How_to_Print_Using_Apple_A irPrint.pdf
