I've applied the patch. Thanks!

I don't know just how much usage printing in PythonCAD has received, so
problems like you've faced are likely to affect other users. When the
GTK+-2.10 release appears with printing support built in, I will try
to utilize the new routines when possible, and I'm hoping that printing
abilitiies will improve. I'll still keep the PostScript printing code
around for people not using the new release, which will be the majority
of users for a good while.
