+ * @done: Signal emitted when the print operation run has finished
+ *    doing everything required for printing.
+ * @begin_print: Signal emitted after the user has finished changing
+ *    print settings in the dialog, before the actual rendering starts.
+ * @paginate: Signal emitted after the "begin-print" signal, but
+ *    before the actual rendering starts.
+ * @request_page_setup: Emitted once for every page that is printed,
+ *    to give the application a chance to modify the page setup.
+ * @draw_page: Signal emitted for every page that is printed.
+ * @end_print: Signal emitted after all pages have been rendered.
+ * @status_changed: Emitted at between the various phases of the print
+ *    operation.
+ * @create_custom_widget: Signal emitted when displaying the print dialog.
+ * @custom_widget_apply: Signal emitted right before "begin-print" if
+ *    you added a custom widget in the "create-custom-widget" handler.
+ * @preview: Signal emitted when a preview is requested from the
+ *    native dialog.
+ * @update_custom_widget: Emitted after change of selected printer.
