I understand that technically speaking, anyone could print to it. Theoretically, anyone could print to any printer on an internet connected network. For better or for worse, I am not all that worried about the security of my network. The ip for the printer is in a specifically designated DMZ behind our firewall and the worst possible scenario would be that someone would print out fifty pages of porn. I also believe in the hacker ethic that encourages people to look but not change. Perhaps I am being overly lax about security, but I guess I cannot see why anyone would care to hack into our network.
