I remember this being discussed on HN before. It felt a bit like "till receipts are killing us" which in the context of someone flying a 40 year old plane with noted defects might not be a primary concern. I wanted to buy a thermal printer myself but couldn't find a definitive answer or evidence of the BPA part being a risk. I got one that uses BPS instead - other papers also raised concerns about this, but again I couldn't find direct evidence of health issues associated with the handling of till receipts. I decided as the receipt printer will be used infrequently and I have been handling till receipts for the last 4 decades I wouldn't worry about it. BPA is also present in food cans and plastic bottles - the link you sent states the concentrations are higher in receipts - but at the same time I don't intend on eating the receipts or rubbing them into my skin. Generally I'm quite cautious about chemicals in everyday life, I try and reduce the amount in our house using natural products for cleaning for example. At the same time we're constantly surrounded by toxins so I often find myself having to do this sort of rationalisation to avoid worrying about seemingly everything all the time.
