Printer tracking dots
You're viewing a single thread.
So the yellow dots became public knowledge 20 years ago, and other than a one liner that other tracking methods may exist, nothing about these other methods seems to be published. Surely the three letter agencies haven’t given up on tracking.
I have another question as to why we don't have an open source paper printer.
No market for it. Printers have already become so fucking cheap to make that the manufacturers can't survive unless they overprice their ink.
I'm tempted to see if I can't get some old daisywheel printer running on a modern Linux machine.
