   Specifying a PAGE_SIZE value in conjunction with the SHEET_SIZE
   value is useful for scaling pages to fit a different size of media
   than that for which they were formatted.

   If you do not specify SHEET_SIZE in your PRINT command, the PAGE_SIZE
   value is assumed to be the physical sheet size as well.  In a print job
   where both PAGE_SIZE and SHEET_SIZE are not specified, the DECprint
   Supervisor software assumes the size of the media that is loaded into
   the default input tray.
