I would love to do some fun things with the thermal printer I have lying around, however, I’m not so sure it is possible to get BPA free paper. Even the “BPA free” paper comes with similar molecules like BPS, which has been shown to be just as bad for the human endocrine system. If anyone can correct me on this and point me to some paper I would be comfortable with my kids handling (kids put everything in their mouths), please let me know.

Most of the alternatives today (including the Costco receipt in my pocket) are labeled "phenol free". As I understand it they use vitamin c or a urea derived compound.

Yep! WA State is the first to ban retailers from using phenol paper starting this year. I'd imagine hobbyists buying thermal printers online are likely to end up with the bad stuff, so I think it's good for people to be aware of the issue and the fact that there are cheap alternatives.

		I really appreciate that you mentioned this, I am now very inspired to do a fun thermal printer project with my kids. Thank you!
