Close enough. I think this works, but am not sure:
config.set(gnomeprint.KEY_PAPER_SIZE, "my-paper-size")
Because KEY_PAPER_SIZE = 'Settings.Output.Media.PhysicalSize'
But I'm not sure about which are the valid paper size strings. Perhaps
"US-Letter" works, or perhaps it's just "letter", I don't know. But
judging from this,
------
[GPAOptions] [GPAKeys]
PhysicalSize=A4,A5,USLetter,USLegal PhysicalSize = A4
LogicalOrientation=R0,R90,R180,R270 LogicalOrientation = R90
------
the paper size string should be USLetter.

I think you should use get_size() for this.

AFAIK, there are no such standards. :)

Sorry, but I can't offer much advice on this. If the user doesn't
have the proper font, there isn't much you can do. Also take a look at
this comment in example_04.py:
# Get this font from:
# http://bibliofile.mc.duke.edu/gww/fonts/Unicode.html
# I used the TTF Caslon Roman.
