How would you know it doesn't, if you don't know what's in it?
Regardless, my point is that many BPA-analogue containing products advertise their BPA-free status.

My comment was that BPA is not used in thermal paper as a plasticizer, which that linked study was examining.

Yes, it's a used as a developer, but as is common in many cases when replacing chemicals with other chemicals -- similar chemicals have similar properties. And in fact, some BPA-free thermal paper use BPS for example.
The alternative chemicals for thermal paper are totally different. That's not to say that they are guaranteed safe, but that study is inapplicable.
E.g. one type of paper claims to use Ascorbic Acid (vitamin C). No idea what else is in it of course, but it's not a BGA-analogue plasticizer.
