Most (if not all) color printer makers are printing unique tracking dots on every printed page. But some of them are transparent about it and disclose it to consumers.¹
In any case, in the mid-1980s Xerox and Canon developed the anti-consumer feature decades before it became known to the public in 2004. So certainly we can blame them for surreptitiously assaulting our privacy.
It’s the surreptitious element of this that is the most infuriating. Transparently disclosing the feature to consumers is the socially responsible approach because at least informed consumers know they are signing up for:
- reduction of print quality
- higher cost of consumables (more yellow consumption)
- loss of privacy
- inability to print a black document when yellow ink/toner is empty
Xerox and Canon should be boycotted not just for the anti-consumer feature but for concealing it.
¹ citation needed… I don’t recall where I read that some printer makers are transparent about it. I would like to know which ones are transparent just from a standpoint of knowing where the integrity is.
Update- other threads on this topic:

I’ll have a look at that directive¹ when I get a chance but I have to wonder if it’s then illegal to write your own FOSS f/w for a printer which has no proactive measures – which you would need to do in order to escape the tyranny of manufacturer ink shenanigans and anti-features.
The quality of most consumer printers is insufficient for counterfiets to begin with, but most certainly they aren’t going to handle the holograms.
¹ strange that it would be a directive considering the EU has exclusive competency over the euro.
(update)
The dots show up easily under a blacklight or blue LED. Which means if you are creating artwork for a blacklit party venue, the noise ruins the artwork.
Update
I had a look at EU Directive 2014/62. This seems to be the relavent bit:
I do not interpret anything there as requiring printer makers to pro-actively produce tracker dots.
Note the law thread is here.
