I am referring to the yellow dots which are printed automatically by laser printers. They encode information such as the time the document is printed as well as the serial number. There appears to be quite little information on this subject available on the internet.
I would like to know if anyone has heard of any known cases out there where law enforcement managed to identify the specific printer which produced the document? Is this something viable that could be used to detect corporate espionage or is this a failed attempt that has long been abandoned?
