Usage:
   foo2zjs [options] <pbm-file >zjs-file

	Convert Ghostscript pbm format to a black and white ZJS stream,
	for driving the Minolta/QMS 2300 DL network color laser printer
	and other Zenographics-based black and white printers.

	| foo2zjs -r1200x600 -g10200x6600 -p1 >testpage.zm

   foo2zjs [options] <cmyk-file >zjs-file

	Convert Ghostscript (1-bit) bitcmyk format to a color ZJS stream,
	for driving the Minolta/QMS 2300 DL network color laser printer
	N.B. Color correction is expected to be performed by ghostscript.

Usage:
	zjsdecode [options] < zjs-file

	Decode a ZjStream into human readable form.

	A ZjStream is the printer langauge used by some Minolta/QMS and
	HP printers, such as the 2300DL and LJ-1000.
==============================================================================

GENERAL
These programs convert pbm (B/W) images and 1-bit-per-pixel cmyk images
(both produced by ghostscript) to Zenographics ZJ-stream format. There
is some information about the ZJS format at http://ddk.zeno.com.

With these utilities, you can print to some HP and Minolta/QMS
ZjStream printers, such as these:
     - HP LaserJet 1000		B/W
     - Minolta/QMS 2300 DL	B/W and color

BUGS AND DEFICIENCIES
    - Need to prepend some Postscript to the job to do color correction
    - Needs to support a better input color file format which includes
      explicit page boundary indications.

AUTHORS
The foo2zjs engine program began life as Robert Szalai's 'pbmtozjs'
program.  It also uses Markus Kuhn's jbig-kit compression library
(included, but available at http://www.cl.cam.ac.uk/~mgk25/jbigkit/).

The foo2zjs engine was overhauled by Rick Richardson to add color
support for the Minolta/QMS 2300DL, add command line options, limit
data chunk size to 65536 bytes, and other miscellaneous features.
Rick also contributed the xjsdecode program and the foomatic database
entries for the Minolta/QMS magicolor 2300 DL.
