Whoa, is this a thing? I know gov surveillance is in depth, but wow.

Color laser printers can't be trusted.

Color inkjet printers probably can't either. Networked printers should not be granted internet access. The printer vendor is your enemy, not an ally.

I've never trusted printer vendors (or any vendors to be honest.), and I don't give printers inet access, but the yellow dots are news to me.
