"The Electronic Frontier Foundation (EFF), a consumer privacy and digital rights organization, has analyzed codes embedded in printouts in color laser printers. The code cracked by the EFF was an invisible bar code that contained the serial number of the printer for tracking users as well as the date and time a page was printed.
In Xerox printers the code appears in a pattern of yellow dots visible only with a magnifying glass and a blue light. The codes are supposed to be for government agencies looking out for counterfeit currency printers. "
