How to stop printer notification?

Hello: I am a fairly new NT4 network admin.
Having just installed a server and some new
Win2K workstations I am having a problem finding out how to turn off user notification
from the spooler that the users print job is finished. All printers areon some form of
Jet-direct servers. (cards or stand-alones)

This is a small office, so notification is more a pain than a help. Where do I look
to turn off this service? Only the win2k
machines have this issue.

Thank You
