Photoshop will flag images of banknotes.

I'd be willing to bet 99% of the public do not know.
Hah, I didn't actually know about this until now. Interesting that the homebrew PCB toner transfer gang don't have problems with this? I use a colour laser printer for toner transfers (Lexmark C543dn) and it doesn't produce dots.
Up yours Uncle Sam, I only print ransom notes and love letters in black and white....
Most of the people who are into computers and electronics here knew that for many years, the general public not so much... And a lot of people here still buy their stuff locally, payed in cash. So if I drive to Computer Müller and buy a Xerox Phaser in his shop, he gets the money, I get the printer and that's it. No names involved. OTOH, it would be a real dumb idea to order the printer on Amazon, pay it with your credit card and use it to print the newest IS pamphlets
One reason why I am still using a few of the old but trustworthy HP 4100N Laserprinters.
This knowledge is old, for those in the know.
For Photoshop there is a plugin / patch available, so you can scan banknotes.
Pay cash and never register your printer
Pay cash and never register your printer
And buy them in a different city, far away from where you live.

And make sure is a tethered printer not wifi or ethernet.
I didn't know about this. But I do know about the EURion constellation.
What happens if you print out with a yellow background, does that fool the system?
Pay cash and never register your printer
Too bad about those security cameras in the stores, and the date and time of the sale still tracked

Interesting question. But an entire page, covered in 100% yellow, to trick the system, wouldn't be of much interest to the agencies, I guess

To bad that the serial number is not on the outside of the package.
And if it is, the cameras are not able to show them in an readable solution.
The only thing the cameras show is that you bought a printer.
But not which one of the 10/20 in the shop.
And normally the recordings get deleted after some time.

It mostly is
And if it is, the cameras are not able to show them in an readable solution.
The POS system will happily register at what date/time that serial number was sold
The only thing the cameras show is that you bought a printer.
Including the date and time
But not which one of the 10/20 in the shop.
No, that was already registered in the POS system.
And normally the recordings get deleted after some time.
The camera recordings yes, there you have a point.
Dave, now you are required to teardown a printer and show us where the dots are actually produced.
Maybe there is an easy way to disable it?

Doesn't seem too likely.
According to
Xerox, who developed the first encoding system, the dots are generated by a dedicated chip "way in the machine, right near the laser" that embeds the dots when the document "is about 20 billionths of a second" from printing.

Your last point is the only one that has validity.
If they do have the recordings then they have something concrete to go on.
Even if no recordings then they could go into phone metadata records to find out who was in/near that store at that time and date.
Paid by cash? Search nearby ATM record data for that and previous days for cash withdrawls.
All they need is a list of names to start narrowing down potential suspects, they don't need proof.
Maybe there is an easy way to disable it?
Greatly doubt it.
It will be deeply integrated into the printer system
They would probably just match the printout to the printer if they found it in posession of a suspect. I doubt there is a massive database of who bought which printer. The same as you see typewriter defects matched with ransom notes in old movies.
Personally I don't see why printing your own grid of dots over the entire sheet wouldn't fix them up good. Can you get twice the toner in one spot?
If you knew about this and wanted to get around it, you'd simply get a printer that doesn't do this.
Does this explain why I seem to run out of yellow ink first?
Very Likely.
