As someone who works in IT, I can tell you with absolute certainty that all printers are manufactured in Hell and sent to earth to torture us for our sins.
I hate printers.
Printers are the bane of my existence.
Nothing worse than dealing with printers all day, then coming home to have to deal with a printer at home too.

I get to act as the unofficial IT person at my office, mainly because I am the youngest male here and no one else wants to do it. Because of that, I end up fixing computers, monitors, scanners, printers etc. all the time which I don't really mind during the off season because it gives me work to do, but here we are in the middle of tax season and I just spent 2 1/2 of the 3 hours I blocked out to catch up on the ~20 tax returns I have outstanding working on fixing printers and scanners.
Printers are definitely the worst, but scanners are steadily climbing the ladder of Most Hated Elecctronic Device here at the office.
