I have received reports today from several areas of campus that printers
are being "toner bombed".  If you are responsible for the management of a
printer that has been subject to such an attack, this is a reminder that
you should review the printer security standards document
http://ist.uwaterloo.ca/security/policy/mfp.shtml and implement the
recommendations.  I have included Colin Bell's original alert below.
