One open-plan office.
Many people.
One printer, next to my desk.
Many people needing to print things.
One printer which is all of a sudden making the most hideous noise, similar to that you might hear on Blackpool beach were one of the kids to turn rabid, whip out a butcher's knife and start stabbing all the donkeys.
One person ready to impersonate said kid.
is that an appropriate comment? 
Steal the power cable for the printer. Hide it where nobody will ever find it. As you said on my blog - think of the savings on paper.
