Mac Geekery

The company I work for bought me a new MacPro running OSX 10.4.10. There are several Macintosh computers running on the network operating on the latest system software available. We are printing to an imagesetter that has a software RIP, (Harlequin), that is configured to broadcast several names across the network. (ie., multiple black, multiple neg, etc.) The other machines don’t seem to be experiencing the same problem. The problem is that the new computer I am using is naming files the same name as the printer that I am printing to instead of the actual name of the file. What can I do to get the Macintosh to recognize and send the correct name of the file that I send to the printer. Why does the naming convention matter, you ask? I need to be able to identify the files when they get to the RIP.
