WASHINGTON--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 printed there that could be used to trace the document back to you.Mon Nov 22, 4:00 AM ET by Jason Tuohey, Medill News Service According to experts, several printer companies quietly encode the serial number and the manufacturing code of their color laser printers and color copiers on every document those machines produce. Governments, including the United States, already use the hidden markings to track counterfeiters. 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. "It's a trail back to you, like a license plate," Crean says.

I wonder if I should not print out a resume on my printer. If someone read on it, that it came from a Lexmark, they may question the professionalism. :thumbsup:

In all kidding aside, thanks for the info!

Ayup!

Much to "some" peoples surprise, the U.S. GOVT has been doing things similar to this on copiers, printers, etc for several decades. Methods have varied from the blatantly obvious to semi-covert, most often to save money, but often more money was spent in trying to implement a system.

(I've several printers of different manufactures - my favorite is still a Lex x73. But don't tell HP I ever said that...)

Thanks CGM3,

I think it timed out. It's changed now and should work. If not here it is again.
