Correct page order for some face-up printers

Printers that print pages face-up should deliver pages in reverse
order so that the last page (arriving on top) is page 1. Printers
may signal face-up printing using output-bin-supported and/or
printer-output-tray.

This change checks printer-output-tray for "faceUp" output and
triggers reverse-order printing if found.
