EFF Reveals Codes in Xerox Printers

Just because a document from a color laser printer doesn't carry your name doesn't mean no one can trace it back to you, privacy advocates warn.

The Electronic Frontier Foundation says it has cracked the tracking codes embedded in Xerox Corp.'s DocuColor color laser printers. Such codes are just one way that manufacturers employ technology to help governments fight currency counterfeiting.

Aren't all the printers now embedded just for that reason? I think I remember an episode of CSI where this was featured.
