This was in the news a couple of years ago. The makers of color printers were asked to provide some subtle means of connecting the printer to a print-out to assist the Secret Service in stomping out counterfeiting.
I don't know if B&W printers or the B&W printing done with color copiers has such ID markings. It is possible that such ID marking is not done by every brand of color printer but, naturally, they don't publicize who's got it or not.
