/**
* 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.
