Have you tried setting it up as a local printer? Ive got a 4050n and a 4000n both set up as local printers even though they are on the network and working for the mostpart as long as the printjobs are originating from the server or via an Xvision terminal. Am I getting way off base here or does this fit your scenario? The 4050n was set up under the normal printers manager and will print either portrait or landscape depending on the command string set in my application. The 4000n would only work if I set it up using the HP network printer config in scoadmin and named as "scsilaser" for the model and has yet to print landscape. Either way, as you know, they have to be defined under /etc/hosts. I hope this has helped.
Good Luck!-----Chris [sig][/sig]
