I agree. When I worked on Cisco's printing system, CEPS, we sometimes heard from users who wanted to lock down a particular printer so that "outsiders" couldn't use it. We never implemented that feature. CEPS provided usage logs, and if a user felt that someone was hogging or abusing a printer, he could simply talk to the abuser. That's much more likely to have a successful outcome for the company than putting up a technological barbed wire fence across someone's path.
