Usage:
    $BASENAME [options] [ps-file]

    Foomatic printer wrapper for the foo2oak printer driver.
    This script reads a Postscript ps-file or standard input
    and converts it to Oak Technoligies OAKT printer format.

Normal Options:
-b bits           Bits per plane (1 or 2) [$BPP]
-c                Print in color (else monochrome)
-m media          Media code to send to printer [$MEDIA]
                    0=auto 1=plain 2=preprinted 3=letterhead 4=graytrans
                    5=prepunched 6=labels 7=bond 8=recycled 9=color
                    10=cardstock 11=heavy 12=envelope 13=light 14=tough
-p paper          Paper code [$PAPER]
                    1=letter, 5=legal, 7=executive, 9=A4, 11=A5, 13=B5jis
-n copies         Number of copies [$COPIES]
-r <xres>x<yres>  Set device resolution in pixels/inch [$RES]
-s source         Source code to send to printer [$SOURCE]
                    1=tray1, 4=manual, 7=auto
            Code numbers may vary with printer model.
-2 / -4           2-up, 4-up

Printer Tweaking Options:
-u <xoff>x<yoff>  Set offset of upper left printable in pixels [varies]
-l <xoff>x<yoff>  Set offset of lower right printable in pixels [varies]
-L mask           Send logical clipping values from -u/-l in ZjStream [3]
                  0=no, 1=Y, 2=X, 3=XY

Color Tweaking Options:
-g gsopts         Additional options to pass to Ghostscript, such as
                  -dDITHERPPI=nnn, etc.  May appear more than once. []
-G profile.icm    Convert profile.icm to a Postscript CRD using icc2ps and
                  adjust colors using the setcolorrendering PS operator.
                  $SHARE/icm/ will be searched for profile.icm.
-I intent         Select profile intent from ICM file [$INTENT]
                  0=Perceptual, 1=Colorimetric, 2=Saturation, 3=Absolute
-G gamma-file.ps  Prepend gamma-file to the Postscript input to perform
                  color correction using the setcolortransfer PS operator.

Debugging Options:
-S plane          Output just a single color plane from a color print [all]
                  1=Cyan, 2=Magenta, 3=Yellow, 4=Black
-D lvl            Set Debug level [$DEBUG]
-V                $VERSION
