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.
If that's true, it's a darn good reason to use classic printers :-)
If I bought a printer and found it was puting stuff on the paper that was
not specified by the input data, it would go straight back to the shop as
being defective. Period.
