Printer Sabotage

We were trying to print out some patterns for quilts this evening, only to find that something was wrong with the printer.  We poked and poked at it, and the only thing we can figure that could be the problem is that it is out of ink.  It had plenty the last time we checked, though, and the only printing done has been for the grandhuman, so we are suspicious of sabotage.  But how could Brother arrange to sabotage the printer from his hiding place?
