Ok so my friend said this happened to her. Her mom was asleep and so she got on the computer. After about an hour on the computer she got tired herself so she also went to her room to take a little nap. (the computer is in her room and her moms room is next door.) So anyway while she was in the middle of her nap the printer was going off ( she had her back towards the printer and computer) so she just thought it was her bro printing off some stupid stuff, but then her mom yelled at her to stop printing off stuff that she is trying to sleep. She answered back it's not me ( with her back still turned) it's probley Josh ( her bro's name) But her mom said that he was outside playing basketball. She got up and looked outstide and yeah he was outside playing basketball. She went over to the printer to see what was printing off. All that is said was ''never gave you a scare so I thought I would'' Sounded like a friendly gost to me.
