Yes you've probably called your own mobile phone number to find out where your phone is, but you've gotta be pretty stoned or lost before your print something to find out where the printer is.

I did it just now and was pretty spooked out when I couldn't hear the printer (the CD player was too loud), but instead felt the paper crawling up my leg.

The printer was under the desk.

Not to be confused with "printing something to find out if you have a printer"
