It's an anti-counterfeiting measure. It can't be turned off. It's built into the firmware. But honestly it's retarded because who the fuck would try to print out a fucking dollar on a laser printer and pass it off? Just fucking stupid.

Wouldn't work if they already had you as a suspect and knew your printer's serial number. You'd just have to overlay the true dot pattern onto the printed document and you'd clearly see that 100% of the overlaid dots line up with the printed document, even if there is random noise.
Also probably wouldn't in general, since a sufficiently good statistician could probably identify which dots are random and which form a pattern and with the appropriate statistical moments to match the types of pattern used for the secret dots.

>>106119008
The absence of evidence that they've found a monochrome solution isn't evidence of absence. For all you know, they could be printing micro-dots much smaller than normal print resolution. Or printing negative-dots within the actual printed content (i.e. microscopic gaps inside letters). Or maybe they've etched the dots into one of the roller drums inside the printer and it embosses the paper as it rolls through, and if you shine laser light at the correct angle the dots become visible. Or maybe they don't even need to modify the rollers, because there's enough random variation in the machinery of the printer that affects the printed output that you can identify printers with 95% accuracy and that's good enough for "beyond a reasonable doubt."

>>106125650
Thermal printer would be easier. Laser is overkill for sure, just need a thermal resistor. Might don't even need a moving head, if you created (or purchased) a dot-matrix style array of heating elements and just pulsed them as the paper rolls through.

Do police departments still maintain big lists of all the different typewriter models along with text samples for each one?

Considering the idiotic rush to digitize everything over the last few decades I wouldn't be surprised if they've all been thrown out instead of being archived.

If you are a POI it's already over anyways. If you're doing anything illegal the first move would have to be not even becoming a suspect in the first place. This is why opsec is so important and why you still have people getting caught every day selling drugs online while others get away with it for a literal decade because these kinds of retards use their fucking gmail to sign up to the market or that one market that got busted in half an hour because the retard didn't even correctly configure tor, just used clearnet http.

I'm trying to assume that people objecting to printer fingerprints do so solely for privacy reasons and not because they're trying to do something illegal.
But the way I figure it, using an older device that lacks them will make you glow almost as hard. It'd be like browsing the internet on netscape. Sure - if you can get the site to work at all - it will not support most of the things that fingerprints users. But the fact that it returns absolutely nothing at all will still make you a unique dataset.

Oh definitely if any government agency, police, whatever even a PI looked into you just having such an old printer would definitely arouse suspicion.

you bought the device, you can do whatever you want with it
...unless you ask US laws and big tech companies, according to them you shouldn't own what you bought and paid for, and they can remotely brick whatever e-waste you buy from them, like brother just recently did with a new forced automatic firmware update that implements ink DRM
