I guess you are right, and using the fontmap option does not seem to make
any difference; when I use e.g. times in the canvas and override it
through the fontmap with verdana, I get verdana in the postscript. If I
use e.g. "clean" instead of verdana I get something that looks like
courier. So it looks like the good news is that I don't need to bother
trying to get the fontmap working when the font name contains white

Nice, i did not know that this is possible, but unfortunately this is no
option for me. I want that my app can be run on any linux machine, so I
would have to ship my own fonts to know where exactly the files are.
I wonder if there is some way to determine from within Tkinter which
fonts can't be used with postscript; if yes I could simply remove these
from the menu where the font can be selected, I could live very well with
that. What's bad is that the font that is printed is not the one the user
sees on the screen.
