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, such as these:
- HP LaserJet 2600n mono or color
- HP LaserJet 1600 mono or color
- HP LaserJet CP1215 mono or color
