GENERAL
This program converts pbm (B/W) images and 1-bit-per-pixel cmyk images
(both produced by ghostscript) to Zenographics LAVAFLOW format.
With this utility, you can print to some HP and Minolta/QMS printers,
such as these:
Model 0:
- Konica Minolta magicolor 2490 MF B/W and color
- Konica Minolta magicolor 2530 DL B/W and color
- Xerox Phaser 6115MFP B/W and color
Model 1:
- Konica Minolta magicolor 2480 MF B/W and color
NOTE: Copies is unimplented!
Model 2:
- Konica Minolta magicolor 1600W B/W and color
- Konica Minolta magicolor 1680MF B/W and color
- Konica Minolta magicolor 1690MF B/W and color
- Konica Minolta magicolor 4690MF B/W and color
- Oki C110 B/W and color
- Xerox Phaser 6121MFP B/W and color
