* SECTION:gtkprintsettings
* @Short_description: Stores print settings
* @Title: GtkPrintSettings
*
* A GtkPrintSettings object represents the settings of a print dialog in
* a system-independent way. The main use for this object is that once
* you've printed you can get a settings object that represents the settings
* the user chose, and the next time you print you can pass that object in so
* that the user doesn't have to re-set all his settings.
*
* Its also possible to enumerate the settings so that you can easily save
* the settings for the next time your app runs, or even store them in a
* document. The predefined keys try to use shared values as much as possible
* so that moving such a document between systems still works.
*
* <!-- TODO example of getting, storing and setting settings -->
*
* Printing support was added in GTK+ 2.10.
