Color printers, yes. Still quite visible with a blacklight and a loupe. Black and white printers may have their own constellation embedded in the dithering but EFF is no longer a friend to computing freedom so they might just be keeping quiet about news on the subject in alliance with other leftist orgs.
I'm thinking of the sure-to-happen future where any file produced by your computer will be cryptographically signed with identification marks about the computer. Files lacking the signature will wind up being the odd ones out that won't load, or get flagged by applications that send files (or sites that host them).
Don't printers already print a secret watermark, or is that an urban legend? It's not as if people are actually printing that garbage (I assume).

All the more reason to support open source, because then there will be versions of the software out there preventing such cryptographic signings.
