Receipt printers are thermal and they print all day long.

Thermal printers use a thin wire that heats up in certain sections. The paper is heat sensitive. Funny though I discovered you can erase a thermal image using a highlighter pen (at old job where clerks had to highlight a section. Ooops!)

The paper is probably more of a danger since thermal paper supposedly is loaded with BPA.

I'm not saying there is a risk of fire but

Not continuously, and not fully black pages.

Apparently not the case any more.

There are several types still in circulation from what I gathered.

The common white/greyish ones might still be a health risk.

Supposedly these blue ones that some shops have adapted is a lot better (and even recyclable?).

That's been banned in the EU since 2020, the question is if its replacement BPS isn't just as bad... [1]
