I have a few PDFs that do so. You can change paper sizes too, which will generally cause a different paper tray to be used; you might also be able to tell the printer directly to switch trays, just as you can turn duplex, stapling and collation features off and on. I've used software that did this in the past. Whether gtk can do it I have no idea.

At the time I wrote my message I was under the impression I was sending one stream of PCL to the printer and switching trays, but in fact I am sending two separate streams. (with my non-GTK software) Changing trays may be out of the question, but I do know that Postscript allows per-page paper orientation changes. I have a few PDFs that do so. The software that is demanding this is in the pharmaceutical industry where they need all sorts of odd shaped data to print in different ways to different paper sizes and trays in one go. I have it working for me now without too much pain, but if I ever have an epiphany I'll be sure to share it.

switch printer tray during printing
Does anyone know if GTK allows switching print trays in the middle of a GtkPrintOperation? I tried setting the source to Tray 2 in the request-page-setup signal for the second page, but this did not work. The second page printed to Tray 1 (default).
