Anonymous printouts may carry your fingerprint

Anonymous printouts produced by your color printer may treacherously carry your printer's serial number and timestamp in the form of an invisible matrix of yellow dots.

From Wikipedia:
Printer steganography is a type of steganography – "hiding data within data"[1] – produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox brand color laser printers,[2] where tiny yellow dots are added to each page. The dots are barely visible and contain encoded printer serial numbers and timestamps. Unlike many forms of steganography, the hidden information is not intended to be available from a computer file, but to allow serial number and time of printing to be determined by close examination of a printout.

Hence why, among other reasons, the Russians have been spending a LOT of money buying up as many old fashioned Typewriters... yes you read that right, Typewriters! ... as they can possibly get their hands on.
