Enlightenment came from thinking about it. :) I concentrated too much
on the firmware aspect. I suspect firmware may only be needed with older
printers. Maybe the newer printers have a Host Based Printer Language
Interpreter.

Henrique de Moraes Holschuh and you are correct. If the printing side of
the MFP requires the plugin it is a host-based printer and the hbpl1
library would be used. Sorry for the misleading up a blind alley.

Even if a colour laserjet MFP can get by for printing without the plugin
it probably requires it for scanning.
