You can be tracked by your printer

The Electronic Frontier Foundation (EFF) has reported that some color laser printers are printing unique identifiers that allow trained readers to decode the month, day, year, and time any page was printed, along with the printer's serial number and manufacturer. The technology is apparently being implemented to prevent counterfeiting, but the EFF notes that no laws regarding the information's use currently exist, and that most people don't even know their printers are automatically including this information on every page they print. The EFF has a summary of what they know, along with a guide to decoding the information, complete with sample images.

On a separate (more humorous) note, the EFF is now selling shipping tape printed with the fourth amendment (find it in the EFF store). BoingBoing suggests you cover your luggage zippers with it next time you fly.
