PAGE_ORIENTATION

   PAGE_ORIENTATION=logical-orientation

   Specifies the orientation of printed output on the logical page.

   Logical-orientation can be PORTRAIT or LANDSCAPE.  If you do not
   specify PAGE_ORIENTATION, it defaults to the page orientation
   associated with the print queue.  If there is no page orientation
   associated with the queue, the default is PAGE_ORIENTATION=PORTRAIT.

   The layup feature uses the page orientation in determining how to
   place the pages on the sheet.  If the DATA_TYPE is POSTSCRIPT and
   the layup feature is not in use, this parameter is ignored.
