Usage:
$BASENAME [options] [ps-file]
Foomatic printer wrapper for the foo2hbpl2 printer driver.
This script reads a Postscript ps-file or standard input
and converts it to a Xerox HBPL version 2 stream.
Normal Options:
-c Print in color (else monochrome)
-C colormode Colormode [$COLORMODE]
10=ICM RGB 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=plain, 2=bond, 3=lwcard, 4=lwgcard, 5=labels,
6=envelope, 7=recycled, 8=plain2, 9=bond2,
10=lwcard2, 11=lwgcard2, 12=recycled2
-p paper Paper code [$PAPER]
1=A4, 2=B5, 3=A5, 4=letter, 5=executive,
6=fanfoldgermanlegal/folio, 7=legal, 9=env#10,
10=envMonarch, 11=envC5, 12=envDL
-n copies Number of copies [$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]
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
