+ * SECTION:gtkprintoperation
+ * @Title: GtkPrintOperation
+ * @Short_description: High-level Printing API
+ * @See_also: #GtkPrintContext, #GtkPrintUnixDialog
+ *
+ * GtkPrintOperation is the high-level, portable printing API.
+ * It looks a bit different than other GTK+ dialogs such as the
+ * #GtkFileChooser, since some platforms don't expose enough
+ * infrastructure to implement a good print dialog. On such
+ * platforms, GtkPrintOperation uses the native print dialog.
+ * On platforms which do not provide a native print dialog, GTK+
+ * uses its own, see #GtkPrintUnixDialog.
+ *
+ * The typical way to use the high-level printing API is to create
+ * a GtkPrintOperation object with gtk_print_operation_new() when
+ * the user selects to print. Then you set some properties on it,
+ * e.g. the page size, any #GtkPrintSettings from previous print
+ * operations, the number of pages, the current page, etc.
+ *
+ * Then you start the print operation by calling gtk_print_operation_run().
+ * It will then show a dialog, let the user select a printer and
+ * options. When the user finished the dialog various signals will
+ * be emitted on the #GtkPrintOperation, the main one being
+ * #GtkPrintOperation::draw-page, which you are supposed to catch
+ * and render the page on the provided #GtkPrintContext using Cairo.
+ *
+ * <example>
+ * <title>The high-level printing API</title>
+ * <programlisting>
+ * static GtkPrintSettings *settings = NULL;
+ *
+ * static void
+ * do_print (void)
+ * {
+ * GtkPrintOperation *print;
+ * GtkPrintOperationResult res;
+ *
+ * print = gtk_print_operation_new ();
+ *
+ * if (settings != NULL)
+ * gtk_print_operation_set_print_settings (print, settings);
+ *
+ * g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
+ * g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);
+ *
+ * res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
+ * GTK_WINDOW (main_window), NULL);
+ *
+ * if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
+ * {
+ * if (settings != NULL)
+ * g_object_unref (settings);
+ * settings = g_object_ref (gtk_print_operation_get_print_settings (print));
+ * }
+ *
+ * g_object_unref (print);
+ * }
+ * </programlisting>
+ * </example>
+ *
+ * By default GtkPrintOperation uses an external application to do
+ * print preview. To implement a custom print preview, an application
+ * must connect to the preview signal. The functions
+ * gtk_print_operation_print_preview_render_page(),
+ * gtk_print_operation_preview_end_preview() and
+ * gtk_print_operation_preview_is_selected()
+ * are useful when implementing a print preview.
