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

	Foomatic printer wrapper for the foo2lava printer driver.
	This script reads a Postscript ps-file or standard input
	and converts it to LAVAFLOW printer format.

Normal Options:
-c                Print in color (else monochrome)
-C colormode      Colormode [$COLORMODE]
                    1=Photos, 2=Photo and text, 3=Graphics and text
                    10=ICM color profile (using -G *.icm file)
-d duplex         Duplex code to send to printer [$DUPLEX]
                    1=off, 2=longedge, 3=shortedge
-m media          Media code to send to printer [$MEDIA]
                    1=standard 4=transparency 20=thick stock 22=envelope
                    23=letterhead 25=postcard 26=labels 27=recycled
                    28=glossy
-p paper          Paper code [$PAPER]
                    1=executive 2=letter 3=legal 25=A5 26=A4 45=B5jis
                    65=B5iso 80=envMonarch 81=env#10 90=envDL 91=envC5
                    92=envC6 835=4x6\" 837=10x15cm
-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=upper, 2=lower, 4=manual, 7=auto
		    Code numbers may vary with printer model.
-t                Draft mode.  Every other pixel is white.
-2/-3/-4/-6/-8/-10/-12/-14/-15/-16/-18
                  Print with N-up (requires psutils)
-o orient         For N-up: -op is portrait, -ol is landscape, -os is seascape.

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
-P                Do not output START_PLANE codes.  May be needed by some
                  monochrome-only printers.
-X padlen         Add extra zero padding to the end of BID segments [16]
-z model          Model: 0=2530DL or 2=1600W (LAVAFLOW) or 1=2480MF (OPL) [0]

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
