Color laser
printers output a serial number indicator of some sort by
a near-invisible pattern of yellow pixels overlaying the printed
image. I imagine it's not 100% reliable but apparently it's been in
place for some time.
It sounds like tin-foil-hat black-helicopter
stuff, but I found
multiple stories about it online in places like The Standard.
If I caught my printer doing that, I would tell them to fix it. If
they tried to claim it was a feature, or otherwise refused, I'd return
it and find a printer that printed what - and nothing but what - it was
given to print.
