Monochrome HBPLv2 B/W Xerox models currently supported by foo2hbpl2 are:
- Xerox Phaser 3010 B/W
- Xerox Phaser 3040 B/W
- Xerox WorkCentre 3045 B/W
However there are others, such as WorkCentre 5016/5020, which use rastertoxrrb1 executable and seemingly uses different output structure.
Check if it's supported.
