Anyone seeing this?

Xerox DocuCenters, Xerox Gateway, latest client (4.9 sp1a, or 3.4). Any
attempt to print to NDPS printer results in: "could not start print job",
or printer is not available, or "Windows cannot print due to a problem with
the current printer setup", etc. etc. Basically, the client cannot see the
printer although it appears in Control Panel and can access its Properties.
Have tried recreating printer using Novell gateway but same results.

If we backrev the client to 4.83 or 3.32, the printer works just fine.
Strictly a Xerox NDPS issue for us.

Any clues out there?
