+ * 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.
