I own a Pixma MX922, printing from an iMac. I want to print a 5x7 photo. I loaded 5x7 paper in the upper tray. Using the Photos app on the iMac, and also the Preview app, I specify the paper size as 5x7, and set the printing up the way I want. However, the printer keeps grabbing plain paper from the lower tray. When I go into the print settings within the apps, all I see is "cassette" as the paper source; I don't see where I can force it to the upper tray.
