Web Jetadmin Auto Groups are constantly looking for conditions on printers and as soon as the condition is met the printer will be added/removed to/from the group automatically.  If the Auto Group policy has been set Web Jetadmin will perform the specified task in the policy as soon as a printer has been added/removed from the Auto Group.  Auto Group policies are useful in automating device maintenance tasks such as disabling/enabling protocols and functions.
