Print queues that have been orphaned in Active Directory may continue to appear in Active Directory, even though the print server no longer hosts the print queue and Printer Pruner is configured correctly and has had adequate time to attempt to remove the object from Active Directory.
Printer Pruner detects that a given PrintQueue object is orphaned by contacting the print server and comparing the printer object to the Active Directory PrintQueue object. If the printer on the print server restricts access to Printer Pruner, Printer Pruner cannot perform the comparison and cannot delete the PrintQueue object.
For proper Printer Pruner operation, a printer must grant access to the Everyone group and/or the Domain Controllers group.
By default, when a printer is created, the Everyone group is granted Print access. If this permission is removed and the printer is published, Print access must be granted for the Domain Controllers group on the printer. Otherwise, Printer Pruner cannot do its job and Active Directory will contain stale PrintQueue objects.
Make sure that the Everyone group or the Domain Controllers group has access to all printers that are published in Active Directory.
