foo2zjs-wrapper

Convert Postscript into a ZJS printer stream

foo2zjs-wrapper [options] [ps-file]

foo2zjs-wrapper is a Foomatic compatible printer wrapper for the foo2zjs printer driver. This script reads a Postscript ps-file or standard input and converts it to Zenographics ZjStream printer format for driving the Minolta/QMS 2300 DL network color laser printer and other Zenographics-based printers.

This script can be used in a standalone fashion, but is intended to be called from a printer spooler system which uses the Foomatic printer database.

Normal Options
These are the options used to select the parameters of a print job that are usually controlled on a per job basis.

-c

Print in color (else monochrome).

-C colormode

Color correction mode [0].

-d duplex

Duplex code to send to printer [1].

-m media

Media code to send to printer [1].

-p paper

Paper size code to send to printer [1].

-n copies

Number of copies [1].

-r xresxyres

Set device resolution in pixels/inch [1200x600].

-s source

Source (Input Slot) code to send to printer [7].

-t

Draft mode. Every other pixel is white.

-T density

Print density (1-5). The default is 3 (medium).

-2 -3 -4 -5 -6 -8 -9 -10 -12 -14 -15 -16 -18

Print in N-up. Requires the psutils package.

-o orient

Orientation used for N-up.

Printer Tweaking Options
These are the options used to customize the operation of foo2zjs for a particular printer.
-u
xoffxyoff

Set the offset of the start of the printable region from the upper left corner, in pixels [varies with paper size]. The defaults should work on the 2200DL and 2300DL, and have not been tested on any other printers.

-l xoffxyoff

Set the offset of the end of the printable region from the lower right corner, in pixels [varies with paper size]. The defaults should work on the 2200DL and 2300DL, and have not been tested on any other printers.

-L mask

Send the logical clipping values from -u/-l in the ZjStream. foo2zjs-wrapper always runs Ghostscript with the ideal page dimensions, so that the scale of the image is correct, regardless whether or not the printer has unprintable regions. This option is used to move the position of the clipped image back to where it belongs on the page. The default is to send the amount which was clipped by -u and -l, and should be good in most cases.

-P

Do not send START_PLANE codes on monochrome output. May be needed by some monochrome-only printers, such as the HP LaserJet 1000.

-X padlen

Add extra zero padding to the end of BID segments. The default is 16 bytes. Padding 16 bytes of zeroes is needed for older ZjStream printers, such as the Minolta 2200DL and HP LaserJet 1000, and seems harmless to newer ones, such as the Minolta 2300DL. So the default should be good for all cases.

-z model

Model. Default is 0.

Color Tweaking Options
These are the options used to control the quality of color output. Color correction is currently a WORK IN PROGRESS.
-g
gsopts

Additional options to pass to Ghostscript, such as -g“-dDITHERPPI=nnn”, etc. This option may appear more than once.

-G profile.icm

Convert profile.icm to a Postscript color rendering dictionary (CRD) using foo2zjs-icc2ps and adjust the printer colors by using the Postscript setcolorrendering operator. (WORK IN PROGRESS).

-G gamma-file.ps

Prepend gamma-file.ps to the Postscript input to perform color correction using the setcolortransfer Postscript operator. For example, the file might contain:
{0.333 exp} {0.333 exp} {0.333 exp} {0.333 exp} setcolortransfer

-I intent

Select profile intent from the ICM file. 0=Perceptual, 1=Colorimetric, 2=Saturation, 3=Absolute. Default is 0 (perceptual).

Debugging Options
These options are used for debugging foo2zjs and its wrapper.
-S
plane

Output just a single color plane from a color print and print it on the black plane. The default is to output all color planes.

-D level

Set Debug level [0].

Create a monochrome ZjStream from a Postscript document, examine it, and then print it using a RAW print queue:

foo2zjs-wrapper testpage.ps > testpage.zm
zjsdecode < testpage.zm
lpr -P raw testpage.zm

Create a color ZjStream stream from a Postscript document:

foo2zjs-wrapper -c testpage.ps > testpage.zc

/usr/bin/foo2zjs-wrapper

foo2zjs(1), zjsdecode(1)
