Big Brother is watching your printouts

Government Uses Color Laser Printer Technology to Track Documents

Next time you make a printout from your color laser printer, shine an LED flashlight beam on it and examine it closely with a magnifying glass. You might be able to see the small, scattered yellow dots printer there that could be used to trace the document back to you

Peter Crean, a senior research fellow at Xerox, says his company's laser printers, copiers and multifunction workstations, such as its WorkCentre Pro series, put the "serial number of each machine coded in little yellow dots" in every printout. The millimeter-sized dots appear about every inch on a page, nestled within the printed words and margins.

Guess I should bring my old dot matrix printer out of retirement in order to print documents without Big Brother watching. I wonder if this thing is even legal in countries that have stricter privacy laws.
