This gonna be pretty important in the next years... people, if you plan on printing protest flyers and pamphlets, either get them done in a professional print shop (if you know someone you can trust, that is), or at the very least buy the printer in cash, never ever connect it to the Internet, and only connect it via USB to a Linux computer - macOS and Windows both will install printer drivers automatically that might phone back to the mothership and link your printer ID to some sort of identifier.

Or, you know, just print massive quantities of valid but randomized tracking dots all over the document using a printer you bought with cash?

Could we just print using yellow paper to make the dots indistinguishable from the background?

Melted toner pallets are shiny and contrast well against paper. I'd set the document background to be a sold yellow before printing it (assuming the privacy invading dots are guaranteed to be yellow).
