{By default, full page printing is disabled. In this case, the origin of
the QPrinter's coordinate system coincides with the top-left corner
of the printable area. If full page printing is enabled, the origin of
the QPrinter's coordinate system coincides with the top-left corner of
the paper itself. In this case, the device metrics will report the
exact same dimensions as indicated by PageSize. It may not be
possible to print on the entire physical page because of the printer's
margins, so the application must account for the margins itself.
We can set this property from QtLCL OsPrinters too.
