/*
GENERAL
This program converts 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 this utility, you can print to some HP printers, such as these:
- Samsung CLP-300 -z0
- Samsung CLP-600 -z1
- Samsung CLP-310 -z2
- Samsung CLP-315 -z2
- Samsung CLP-325 -z2
- Samsung CLP-365 -z3
- Samsung CLP-610 -z2
- Samsung CLP-620 -z3
- Samsung CLX-2160 (printer only) (like CLP-300)
- Samsung CLX-3160 (printer only) (like CLP-300)
- Samsung CLX-3175 (printer only) (like CLP-315)
- Xerox Phaser 6110 (like CLP-300)
- Xerox Phaser 6110MFP (printer only) (like CLP-300)
AUTHORS
This program began life as Robert Szalai's 'pbmtozjs' program. It
also uses Markus Kuhn's jbig-kit compression library (included, but
also available at http://www.cl.cam.ac.uk/~mgk25/jbigkit/).
The program was overhauled by Rick Richardson to limit data chunk size
to 65536 bytes, add command line options, add color support,
and other miscellaneous features.
