help connecting a plotter to HP-UX

While this is technically a newbie question, it is an advanced/expert situation so that's why I posted it here.

I'm an intern at a company that recently aquired another business that ran off the HP-UX 10.20 unix platform. They (and myself) do not have any experience with it. I have spent virtually my entire day scouring the internet and trying various commands in order to fix this problem, but I have had no luck.

The system came with an hp 7595a plotter which we need to connect to print drawings stored on the system.

I have gone to the printer jobs menu in unix and it shows a printer called paintjet. The current configuration is with a cable running from the plottter to a serial port on the c160 and then another cable from the plotter connected to an Emulex Performance 2500 which is connected at the c160's ethernet port.

This does not seem to tbe printer though. The program I am trying to plot with is Unigraphics V.15, but I have even tried printing with the text editor and it does not help.

Any help would be EXTREMELY appreciated.

Thanks!
