Aside from being stoned or lost there are actually uses for printing something to find out where the printer is.
Imagine the scenario... you've just landed that support job in an organisation that has felt the wrath of an admin who enjoyed thinking up esoteric names for machines dotted around the campus. Naming all the machines after obscure Russian poets may be a mark of a highly intelligent mind, but really doesn't help when you're trying to find one for some reason.
So when the camel's back breaks, you've got to find it. You could use traceroute, DNS records and switch configurations to find it, but that's time consuming. So out of each printer comes a single sheet of paper...
