/**
 * 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
 * "draw-page", which you are supposed to catch
 * and render the page on the provided GtkPrintContext using Cairo.
 *
 * $(DDOC_COMMENT 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_preview_render_page(),
 * gtk_print_operation_preview_end_preview() and
 * gtk_print_operation_preview_is_selected()
 * are useful when implementing a print preview.
