Every printer includes a unique dot array. Required by law. There's a video of a ballot printer walking through their prices and mentions some of this. https://thedonald.win/p/11PpBJPFZr/good-news-everybody-the-printer-/c/

Agree about aspects of this being in the trust sessions category, but qualifying printers must print these unique marks which aid law enforcement in busting currency counterfeiting and more.
