ALTERNATE

     ALTERNATE=[LEFT|RIGHT|TOP|BOTTOM]

     Shifts every other page image in preparation for two-sided
     printing.  Use this option in combination with the MARGINS
     option.

     Specify one of the words, LEFT, RIGHT, TOP or BOTTOM to
     cause the DECprint Supervisor to shift alternate page side
     images appropriately.  Specifying LEFT or RIGHT alternates
     the left and right margins you specify with the MARGINS
     option (those margins along the long edge of a sheet of
     paper).  Specifying TOP or BOTTOM alternates the top and
     bottom margins you specify.

     If you specify ALTERNATE with no option values, left and
     right margins alternate.
