I can't seem to replicate this problem.  See attached screenshot.  I've 
enabled the windows firewall on a Win7 client that prints fine and 
configured it to block all inbound connections.  However, this client 
still prints immediately and I don't see any timeouts or access denied 
errors on the print server.

What do I need to do, to replicate the errors below when printing?
