/*
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 Xerox and Dell, such as these:
- Dell 1355cnw B/W and color
- Dell C1765nf/nfw MFP B/W and color
- Epson AcuLaser_M1400 B/W
- Epson AcuLaser_CX17NF B/W and color
- Fuji Xerox DocuPrint CM205 B/W and color
- Fuji Xerox DocuPrint CM215 B/W and color
- Fuji Xerox DocuPrint M215 B/W
- Fuji Xerox DocuPrint P205 B/W
- Xerox WorkCentre 3045 B/W
- Xerox WorkCentre 6015 B/W and color
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 for the
Minolta/QMS 2300DL, and other miscellaneous features.
