Thanks for the pointers.  However this turns out to be a little more
complicated than I had hoped :-(

This is what I have so far, but it prints one blank page:

    def print_text(text):
        p = gtk.PrintOperation()
        
        p.connect("begin-print", begin_print)
        p.connect("draw-page", draw_page)
    
        r = p.run(gtk.PRINT_OPERATION_ACTION_PRINT_DIALOG)
    
        print r
    
    
    def begin_print(op, ctx):
        op.set_n_pages(1)
    
    
    def draw_page(op, ctx, page_nr):
        cairo_ctx = ctx.get_cairo_context()
    
        layout = cairo_ctx.create_layout()
        layout.set_text('Some text'.decode('utf8'))
        desc = pango.FontDescription("sans 28")
        layout.set_font_description(desc)
    
        cairo_ctx.move_to(30, 30)
        cairo_ctx.layout_path(layout)
    
    
    print_text()

Any more pointers?
