How can I allow members of the Printer Operators group to Add Printers?

A. While members of the Print Operators group can stop and restart the Print Spooler, modify jobs and other admin functions they cannot add or modify the actual printers. This can be changed by performing the following:

1. Start the registry editor (regedt32.exe, not regedit.exe)
2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors
3. From the Security menu select Permissions
4. Click the Add button
5. Select "Printer Operators" and give them Full Control access. Click OK
6. Close the registry editor

Stop and start the machine for the change to take effect. Alternatively just stop and start the print spool service,

C:\> net stop spooler
C:\> net start spooler
