* @Short_description: A page setup dialog
* @Title: GtkPageSetupUnixDialog
*
* #GtkPageSetupUnixDialog implements a page setup dialog for platforms
* which dont provide a native page setup dialog, like Unix. It can
* be used very much like any other GTK+ dialog, at the cost of
* the portability offered by the
* [high-level printing API][gtk3-High-level-Printing-API]
*
* Printing support was added in GTK+ 2.10.
