I'd like to also add people who print something and leave it there in the printout tray for days at a time, then have the nerve to get mad when 3 days later they come looking for it and it's been tossed. Uhhh, next time, get up and get it right after you print it.

Adjacent to that would be people printing on legal paper and not getting up to put the legal paper in the bypass tray, so then every job after that is held up in the queque because the person never remembers to put the legal paper in.
