I only know enough about Unix to get me in trouble:

I have an old UNIX SCO OpenServer 5 that I am phasing out. It had been connected to an HP laserjet via a serial port connection. As part of the phase out I disconnected and removed the workstations leaving only the server. I didn't think I was going to need to print from this machine so I disconnected the printer as well.

Now I found that I will indeed need the printer. I reconnected the printer with a new serial cable, but the machine does not recognize it. Since I never removed any of the drivers I assumed that it would pick up right where I left off.

What do I need to do to reinstall the printer?
