I could add a gtk_print_operation_run_async() call that shows the dialog
and then returns to the main mainloop, using signals to drive the dialog
etc. However, even that should really call gtk_window_set_modal on the
print dialog to make it modal to the GtkWindowGroup of that window, so
I'm not sure how much of a difference this makes.

Paolo, does gedit make separate window groups for each toplevel window?
