I think you just need to translate the output to the position you want
it on the page, e.g.:

In draw_page():
    cr = gtk_print_context_get_cairo_context(context);
+   cairo_translate (cr, 0, -A4_PAGE_HEIGHT * page_nr);
    goo_canvas_render(GOO_CANVAS(data->canvas), cr, &bounds, 0.0);

That seems to work here.

We should add some documentation for this.
