/**
 * Description
 * 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_print_preview_render_page(),
 * gtk_print_operation_preview_end_preview() and
 * gtk_print_operation_preview_is_selected() are useful
 * when implementing a print preview.
 * Printing support was added in GTK+ 2.10.
