Domain Controllers looking for printers

I have noticed lots of information entries in the System event logs of our domain controllers. It seems that they are looking for printers locally installed on workstations. Because these entries are out of hours, they are not finding them and so add to the log.

The additions are not listed as errors so I havent really noticed them before. It doesnt seem to be a problem other than it is filling up the event logs.

What I would like to know is: 1) Why is this happening?
2) Can I turn this feature off without anything bad happening?

thanks

 

S'ok, I found the answer. The File Replication Service was not working
