Incredible. Instead of just creating online trash that nobody wants to read, it can create physical trash too! For maximum art, it can feed directly into a shredder.

Indeed. But there are some good BPA-free alternatives on the market

Is there any way to verify that without getting a Lab to do an analysis? I'm not sure if I can trust stuff labelled BPA-Free from Amazon for example.

Even if they are, that doesn't mean they're safer

Extremely shortsighted take.

I currently use a local LLM to scan my notes, meeting transcripts, todo list and calendar. I currently have an iPad that displays some items (e.g. if I have important personal tasks to do today that I might have forgotten) and I would love it to be printed out like this.

Nothing to do with generating novel text, it's just used as a flexible API to my existing text and items.

That study looked at 6 similar plasticizers.

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.

Buy from a reputable seller for anything important, instead of amazon.

Or, there are apparently at-home testing chemicals that look simple to use. I haven't done it myself though.

This is awesome! I have a very hacky prototype doing something similar, you've put way more effort into PrinterCow and it looks great. What's the tech? (I'm crossing my fingers for Elixir/Nerves but I suspect that's still a bit niche) Edit, I'm now signed up - though I'm struggling to find the install instructions for the RPi.

Thanks so much! Elixir was on my list but decided for Fastify (Node v22), Postgres and Vue3 in the end as these are the things I am more familiar with. :) The command is on the Printercow homepage - though proper docs are coming by end of the week.

Which then again could have AI integrations of its own! Imagine the endless possibilities of AI shredding.

A dumpster fire works well too: https://gizmodo.com/watch-your-feelings-about-2020-burn-in-a...
