STAPLE=staple-position

    Valid staple-position values are:

        LEFT_CENTER
        TOP_CENTER
        TOP_LEFT
        TOP_RIGHT
        NONE

    These values specify the position of the staple with respect to the
    orientation of the image on the paper.  When NONE is specified, the
    job is printed without stapling, overriding the printer's default
    stapling setting.  Some values of staple-position are not always
    possible, depending on the direction in which the paper is fed
    through the printer.
