How can I flip the card using the Zebra ZXP Series 3?

I need to write text on the back of the card using the Zebra ZXP Series 3 SDK in C#. Documentation is horrid, all I can see is what is contained in this ZBRPrinter file. How can I actually flip the card and write on the back of it? Is that possible?

Note that these are the avialable methods I can call now to do "card movements"

        private static extern int ZBRPRNMoveCardFwd(IntPtr _handle, int prn_type, int steps, out int err);
