Only too glad I could save someone the hours of frustrating
 search it took me to get that far.

Blowed if I can see why; it's just the return value from GetDeviceCaps.
Ah... looking at my email to you underneath yours to me, the line has
been chopped (hope this makes it across the email systems) thus:

printer_resolution [...] = hDC.GetDeviceCaps [unintended line break]
(VERTRES)

which will make Python think that the second value in
the printer_resolution tuple is the function GetDeviceCaps 
and that the (VERTRES) is merely a throwaway value. 
It should, of course, read:

[...] = hDC.GetDeviceCaps (VERTRES)

where VERTRES is the parameter to GetDeviceCaps

> I just used [0] for both args and it was fine(for now).

That'll work because, in any case, the code later on takes
the smaller of the two ratios to determine the scaling factor,
and printer_resolution[0] is the width of the page, which
is going to be the smaller of the two anyway.

Hope it works out for you. I haven't yet bothered to go
into using the Printer Setup dialogue, which truly is a
pain. I'm using a Pygame interface, so I'm trying to cut
down on Windows-esque dialog boxes.
