I have recently migrated my queue printers to NDPS. All printers are
working except for one.

A new HP 9050 with the latest drivers (I also tried older drivers) loads
as a printer fine (iprint) the drivers install to the ndps server fine.

However, when a client tries to install this one printer, it generates a
spooler subsystem error and locks the machine.

Individually installing the driver to each machine and setting up a local
IP port works fine.

Any ideas? I found NOTHING at hp.com (not surprising)
