Doubt. Laser printers were invented in the early 1970s and were common by the mid 1980s. I don’t think this tracking started until inkjets and scanners got good enough that the government got concerned about them being used for counterfeiting, I’d guess mid to late 90s at the earliest.
Aren’t these only produced by laser printers?
Are they in laser as well? This is way older than laser.
