When printing from my iPad to my Lexmark printer the default printer tray is the envelope feeder. The only time I see an option to select a different paper tray (ie the main one) is when I am printing a PDF from within the mail app. Anywhere else this option does not exist. Any insights? Screenshots show print options when printing a PDF within Mail (including option to switch trays on the bottom) vs. printer options anywhere else (identical but missing the option to switch trays).
