From what I understand, thermal paper is one of the worst sources of BPA. It isn’t regulated because it’s not consumed or touching anything you consume usually, but it would be better to consume it than absorb it through the skin because at least the liver processes shit we consume, while shit we absorb can go straight to the bloodstream.
This is on top of being generally the shittiest form of printing by most measures, as the other comments go into. I’d prefer dot matrix or inkjet over thermal paper.











With how many people there are out there, even something that happens to 0.1% of people over their lifetime will happen to 200k people living in the US right now (assuming 200m pop, which I think is low now). Assuming an average life expectancy of 75, that averages 2666.6 per year, or 7.28 per day (assuming every year is a leap year).
I don’t know what the odds are of having kids at 20, but I’d guess the conditional probability of two successive generations both having kids at 20 is way higher than 0.1%, which means there’s more than 7 new ones each day. And any of them might post this kind of thing where they talk about something their grandparent bought new.
