Problem:
You have your ucs@school networks separated into an educative network and a staff network. Both networks contain printers.
Your teachers are able to moderate the print jobs from students but in the module they see the printers from staff network, too.
Solution
Print Moderation shows all printers stored under the LDAP tree object cn=printers,ou=$OU,$LDAPBASE
.
Move your printers out of this tree and they will not be seen in printer moderation.
