We've been using iPrint for a couple of years, but still have some users who print through Netware queues, not NDPS/iPrint. We don't want to migrate these users to iPrint as they may have driver settings that haven't been catered for in our driver profiles, and unexpected popups may alarm certain users :)
Basically we'd like to configure our current desktop build so as to prevent users from being able to add Netware queues, but still allow them to add local, direct IP and iPrinters.
Is there a means of tweaking Windows XP to accomplish this?

Thanks in advance,
