This BBC article documents how some printers secretly print faint dots which identify the printer as well as the date and time a page is printed.

How do I choose a printer which won't do this?

Don't buy or use a color laser printer. The EFF has been advised "all major manufacturers of color laser printers entered a secret agreement with governments to ensure that the output of those printers is forensically traceable".

  • Or remove/hide the dot patterns: bleepingcomputer.com/news/security/…

  • I don't think I have any White-Out(TM) to remove them from the printed page.

  • At this point, I am no longer sure if you are joking, or intentionally misunderstanding my messages.
