When trying to print with a font that has a space in the postscript name,
gnome-print generates a "wrong" ps output.
I'm using Gnome 2.3/2.4 with gnome-print 2.3.1 on Mandrake cooker/9.2rc1

$ ftdump ~/.fonts/stylus.ttf |grep postscript
   postscript: Stylus Regular

In the postscript file, it takes over that space, which makes that
ghostscript interpretates that (Regular) as a new postscript command.
[...]
%%+ font GnomeUni-Stylus Regular
[...]

There is a bugzilla thread at Mandrake, which has more details.

I will attach a fontfile (Stylus.ttf), and 2 postscript files, one in which
a correct font is used, and one which uses a font with a space in the
postscript name.
