To this, I've no answer, since I've never had to print an image - so,
you could check an existing application using libgnomeprint, and do the
conversion.  For example, GThumb uses libgnomeprint to print various
kinds of images:

        http://cvs.sourceforge.net/viewcvs.py/gthumb/gthumb/#dirlist

All I know is that the ::*image methods of Gnome2::Print are similar to
Gtk2::Gdk::Pixbuf in what they want and how they want it.

Ciao,
