No, not really. One reported similar problems some months ago, see
http://www.mail-archive.com/gtk-app-devel-list gnome org/msg10029.html.
Behdad Esfahbod told him to change his code, I already did this but
still get the same results.

For examples see:
http://www.uvena.de/tmp/cairo/print_pango_linux.pdf (fine)
and
http://www.uvena.de/tmp/cairo/print_pango_win32.pdf (broken)

It's printed with the same code. Unfortunately, I didn't manage it yet
to write a small sample programm to show this. The above PDFs are
created by printing with Geany. The relevant code can be found in the
draw_page function in
http://geany.svn.sourceforge.net/viewvc/geany/trunk/src/printing.c?revision=2201&view=markup#l_466

Enrico
