I thought everybody knew about this -it's why you have to forge notes on an inkjet, not a laser.

It was news to me.
I wonder what happens when you take your printed document and run it through a couple of generations of photocopying on different photocopiers. I also wonder if older laser printers don't have this spy technology.

Who pays for the yellow toner?

I've brokered a bunch of Colour Copier leases for customers and often the toner has been free but the service contract includes a per page fee and a per colour fee. We've never tried to audit the counter before but now I wonder if my customers have always been getting charged for yellow even if all they printed was black text.

I can't think where/when I found out now; the question of who pays is interesting though.
