Has anyone got an HP laserjet 2605dn working with Unixware 7.1.3?

The current OS does not have any service packs, and does not have
CUPS. In fact, I would prefer not to mess with CUPS since that would
probably break other printers. Just trying to get a new printer
working on an older system. Entire system likely to be replaced in 6
months.
