We have rolled out iPrint client v04.06.00 to 45 NetWare 6.5 SP2 servers.
We have had this problem randomly at about 10 or 15 of the server
locations so far, and not sure why it is happening.
A user will call because they have tried to print to an iPrint printer.
The print job comes out of the printer but the app they printed from has
the printer box on the screen and the app is stuck. You have to end task
the app. If they try to print again, same thing. We have been
uninstalling the iPrint client and reinstalling it. This seems to fix the
problem but is very time consuming.

Does anyone have any ideas why this would be happening?

I did see one post from Sancxo on 5/11/06 having a similar problem - but
didn't really understand their fix. Our iprint.ini does have a short
install name, but we don't have the AllowUserPrinters= set to "3".
