Some print drivers use a subkey of the server registry to save default settings. 

The driver trys to make a subkey in: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\<printername>\

values can be stored there, but the creation of a subkey is not possible.


The log.smbd on the moment of creation:
