Ashley,
I have a G95 shared throught a NT4 server. I had to put the G95 on an external HP Jet Direct box which gives the printer an IP address on the network. The NT server uses JetDirect Software to print to the printer.
With the jetdirect box, I think, but I have not tried it, that you could install the G95 software onto a computer and tell it to use LPT1 during the install (do not print a test page). Once the install of the G95 software is done, change the port for the G95 to an IP port or the shared printer on the NT server (port).
Unfortunately, the HP Jet Direct boxes are expensive.
Good Luck,
Ryan
