Almost all major printer manufacturers like Xerox, Canon, Brother, HP, Dell, Lexmark etc.
carry this secret code.
you might find the list of printer manufacturers and the printer models which have these codehere.
for see the pattern, you need a blue light, a magnifying glass, or a microscope.
The researchers have given theinstructions here on how to connect the dots.
EFF and its partners began its project to break the printer code with the Xerox DocuColor line.
So far, weve only broken the code for Xerox DocuColor printers, said Schoen.
But we believe that other models from other manufacturers include the same personally identifiable information in their tracking dots.
you’re free to decode your own Xerox DocuColor prints using EFFs automatedprogram.
