Seems like ink printers are safe? Or did I miss something?

It seems like many color printers are unsafe but black & white printers are safe, judging from all the links people shared.

Not all printers, but all color printers. Usually they encode in yellow and is only visible under black light or light boxes. The encoding is a proprietary language the Secret Service commissioned to prevent counterfeiting.

Not really related to printing I guess, but see what happens if you try scanning a $100 bill.

Purchase your printers second hand from offline sources. It won't solve the issue but it will minimize emphasis on the "owner" part of your question.

I think it only applies to inkjet printers (the watermarks are printed using yellow ink on white paper). But don't take that to the bank.

Does inkjet = color and laser = black & white?

With my exceptionally bad luck with printers not working properly, I can't help but feel the secret i.d. number is flawed.
