Use CUPS. If you use anything else and it breaks, you can keep all the pieces (and I'll laugh at you).
Connect to your CUPS admin management page thingie. If you don't know how, look elsewhere.
Tell CUPS it's an HP JetDirect, listening on port 10001. Yes, I know.
In Debian experimental as of 13 October, the HP LJ6/hpijs driver seems to work ok. The LJ6 PCL driver does too.
