this may help you out. I found that my users did not have permission to network'd printers. So I made the following change to allow them add printers that I have made available from my print server. Good luck
There is a setting Computer Configuration/Administrative Templates/Printers called “Point and Print Restrictions”
1. Set it to “Enabled”
2. Put a check box in “Users can only point and print to these servers:”
3. Enter your print server name in the box “servername.domainname.com”
4. Security Prompts – set both to “Do not show”
Now your users should be able to add printers from your print server
