Can anyone help me with this one?

I have a Fp26 DOS legacy app running at a client's office where their Okidata laser jet died. They just replaced it with a HP Laserjet 2100. The Fox app has driver settings for HP Laserjet III, IV, etc. and various other printers (but none for the HP2100).

Does anyone know if this printer can be set to emulate or respond to standard HPIII settings or, if not, how I can locate the printer command set so I can build a dos driver to we can print?

Thanks!
