Since migration from NW6.0 to OES, we have occasional issue of "failed print" after what the job is lost.
Issue is noted at any workstation (XP or W7) occasionally and any printer. Usually "network repair" performed at affected WS would solve the problem.
Before "netwok repair" performed, status of netware connection was checked as well ability of browsing mapped drives. Nothing wrong found here. Also no problem found with printer in case. At the same time some other WS can print normally at the same printer.
Haven't found this problem documented yet. Not even sure if this is iPrint related or not.
We are not able to simulate this. We can only wait when someone report about. Younger users, after one or two telephone help don't calling us anymore so we don't even have a real picture of problem frequency.

Where to start tracing possible error?
