gpb = gdk_pixbuf_new_from_file (your_file)
if (gdk_pixbuf_has_alpha (gpb) {
	gnome_print_rgbaimage (gpc,
		gdk_pixbuf_get_pixels (gpb),
		gdk_pixbuf_get_width (gpb),
		gdk_pixbuf_get_height (gpb),
		gdk_pixbuf_get_rowstride (gpb));
} else {
	gnome_print_rgbimage...
}

The real thing is bit more complicated, as theoretically pixbufs can have
num_channels other than 3, different colorspaces and bits per channel
<> 8. But usually this works.
