Fun fact: part of the reason your printer needs all toners is because it prints an identification pattern unique to the printer on every document (which uses those colors).

Its not even a “modern” printer thing. They’ve done this since the 80s.

But now with modern printers they can have email addresses and locations.

Specifically, it mostly uses yellow in very faint dots imperceptible to the eye. I actually don’t know if it needs every color, or if it’s just yellow, or if it varies by printer.

Scanners and printers will also detect a pattern of dots which indicates “this is money,” embedded in various clever ways in the design of the art of the money of most countries, and refuse to have anything to do with the images.

You don’t own your devices anymore. And it will, steadily, get worse.

Pffft, this is some conspiracy bs, there’s no way…

googles it

Oh shit… OH FUCK

Though, to be clear, it seems like there are already tools available that you can use to print a bunch of tracking dots all over the page, essentially ‘hiding’ the real tracking dots and making them unusable, so it’s not impossible to get around. Still absolutely wild, and thanks very much for mentioning this, I learned something today.

Black ink only printers can’t print in yellow.

Unfortunately there are techniques that work with black and white printers too. I don’t know if any have actually been implemented though.

Dot matrix printers don’t do it.

That doesn’t require tracking when you’re the only guy who still uses a dot matrix printer.

Pretty sure B&W toner is in fact untraceable. Anyone know different?

Fun fact: your electronic devices that render graphics are completely capable and in my opinion almost certainly do this as well. We use a business version of it at our enterprise and while it is additional software layered over windows, it’s completely imperceptible to the naked eye and I doubt such technology wouldn’t be immediately rolled out as quickly as possible by pretty much everyone at a “top secret” level.

those use yellow ink afaik.

the yellow went down when printing b/w only (which we usually did) on our old officejet pro that had separate tanks for each color.

Your fax will include b/w prints of the dust and other edge artifacts of the machine no doubt from the light

You think this is a game!? My fax machine has been detail cleaned, with a custom air-tight gasket sealing the scanner bed. It is situated in a pressurized clean-room with a HEPA filter, behind 2 security doors and monitored by closed-circuit cameras. I’m not an amateur faxer…
