2nd printer problems

I’ve recently added a 2nd lpt port to a windows NT computer. It is an ISA card. I didn’t see any conflicts come up when I brought the machine back up, but if you try to print to it (test page or document) I get the following message: “Error writing to LPT2 for docname: The system cannot find the file specified. Do you wish to retry or cancel the job?” Lpt1 prints fine and is currently attached to another printer. I’ve gone through the troubleshooter a couple of times and everything checks out ok. I reinstalled the printer several times with the latest driver to no avail. I’m thinking that there is a conflict with the new port somewhere but I don’t know how to locate/determine that. Any suggetsions would be greatly appreciated.
