290  * dialog. On platforms which do not provide a native print dialog, GTK+ uses its own, see PrintUnixDialog.
291  *
292  * The typical way to use the high-level printing API is to create a PrintOperation object

294  * from previous print operations, the number of  pages, the current page, etc.

296  * Then you start the print operation by calling run(). It will then show a dialog to
297  * let the user select a printer and options. When the user finishes the dialog various signals will be
298  * emitted by the PrintOperation for you to handle, the main one being draw_page. You should then
299  * render the page on the provided PrintContext using Cairo.
