PrintOperation.addOnBeginPrint

Emitted after the user has finished changing print settings in the dialog, before the actual rendering starts.

A typical use for ::begin-print is to use the parameters from the [class@Gtk.PrintContext] and paginate the document accordingly, and then set the number of pages with [method@Gtk.PrintOperation.set_n_pages].
