33 * SECTION:ctkprintsettings
34 * @Short_description: Stores print settings
35 * @Title: CtkPrintSettings
36 *
37 * A CtkPrintSettings object represents the settings of a print dialog in
38 * a system-independent way. The main use for this object is that once
39 * you’ve printed you can get a settings object that represents the settings
40 * the user chose, and the next time you print you can pass that object in so
41 * that the user doesn’t have to re-set all his settings.
42 *
43 * Its also possible to enumerate the settings so that you can easily save
44 * the settings for the next time your app runs, or even store them in a
45 * document. The predefined keys try to use shared values as much as possible
46 * so that moving such a document between systems still works.
47 *
48 * Printing support was added in CTK+ 2.10.
