/MARGIN=(option[,...])

    Specifies one or more of the four margin options: BOTTOM, LEFT,
    RIGHT, and TOP.

    BOTTOM=n   Specifies the number of blank lines between the end
               of the print image area and the end of the physical
               page; the value of n must be between 0 and the value of
               the /LENGTH qualifier. The default value is 6, which
               generally means a 1-inch bottom margin.

    LEFT=n     Specifies the number of blank columns between the
               leftmost printing position and the print image area;
               the value of n must be between 0 and the value of the
               /WIDTH qualifier. The default is 0, which means that
               the print image area starts as far to the left of the
               paper as the printer can go.

    RIGHT=n    Specifies the number of blank columns between the
               /WIDTH qualifier and the image area; the value of
               n must be between 0 and the value of the /WIDTH
               qualifier. When determining the value of the RIGHT
               option, start at the /WIDTH value and count to the
               left. The default value is 0, which means that the
               print image extends as far to the right as the /WIDTH
               value.

    TOP=n      Specifies the number of blank lines between the top
               of the physical page and the top of the print image;
               the value of n must be between 0 and the value of
               the /LENGTH qualifier. The default value is 0, which
               generally means that there is no top margin.
