That doesn't make sense - obviously black-only laser printers exist and manage to be compliant just fine

That's exactly why the black only printers are so good though. They escape regulation to print yellow dots since they can't print subtle yellow dots.

They still have tracking dots. But at least you can print when yellow is out.

Regulation is "color printers need telltales", not "color prints need telltales"

I do not believe that a colour laser printed can't switch to whatever tracking dots mono laser printers use when out of yellow ink. I'd believe laziness over compliance issues.

Citation needed about tracking dots on B&W lasers. I don't see why they're necessary: the main reason is for anti-counterfeiting. B&W lasers can't be used for printing counterfeit money, for what I hope are obvious reasons.

[gambiting]

I don't know if they have them - but the same argument still applies. If you're printing in mono then no tracking dots are necessary, therefore stop complaining about missing yellow ink.
