While a firewall is definitely a good idea, "insiders" can still abuse printers. In a school environment, the students will often be the ones you are trying to defend against. Many network printers allow you to configure restrictions such that only certain IP addresses can submit jobs. Set that to your print server(s), and set a password on the management UI, and you're in good shape. FYI, in addition to TCP/515, TCP/9100 is used extensively for "direct port printing". -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
