My Postscript printer has two paper trays, and since I don't generally
use letterhead or different size paper, one is never used.  Would it 
be possible to write a short resident program that would trap an
"out of paper" error and switch automatically to the alternate
tray?  That way I could keep them both loaded with the same paper.
I think I know how to switch trays, but handling error messages is
not something I know how to do in Postscript.
