Buying a Printer: Fact vs. Fiction

The Electronic Frontier Foundation maintains a list of color laser printers that, it says, lay down light yellow code-patterns on every print; the dots are viewable in blue light or under magnification. These codes were developed to help the federal government track down criminals who were printing counterfeit cash. But the EFF fears that the codes could also be used to track and monitor anyone who uses those printers. Monochrome laser printers and inkjets don't appear to leave such markings.
