I followed the steps in the answer to a previous question to setup my printer (HP Photosmart C5280) to be used from the iPad (iOS 4.2.1), which worked fine on Ubuntu 10.04. Apple claims, that for printing photos, an available photo tray would be automatically used. But when I print pictures from the iPad, the main paper tray is used.
Is there a possibility to change the configuration to make AirPrint recognize my photo tray?
