If you do this be sure to buy BPA free receipt paper Handling receipt paper is what turned out to be the cause of the high BPA numbers when boba tea was tested https://x.com/natfriedman/status/1899641377002025252

I did! I also use gloves when handling a large amount of the receipts.

I worked as a cashier for years in my teens and twenties though, so it’s probably already in my blood.

I wonder if the author is aware of the health effects of handling thermal paper. https://pmc.ncbi.nlm.nih.gov/articles/PMC5453537/

I suspect the author, like nearly all of us here will get more exposure to BPA from handling supermarket (etc.) receipts than from this gimmick.

Worse: I worked in grocery stores for years as a cashier lol

I've fantasized about fax phone banks for artists to send things out periodically.

The idea of a machine unexpectedly popping out a sheet of paper has gone from "this is all spam" to delightful again.

Physical items in a physical space whereby you call a place and not a person.

We've digitally moved from spaces to individuals and I think that's the main critique of the modern web: somehow networked ourselves but abandoned the networking of ourselves.

You could even do it all digitally somehow and just hook it up to a modern network printer. Whitelisted senders get printed while unrecognized ones enter a digital backlog.

The real desire is to explore the psuedo anonymous nature of the early web in a way that is robust to abuse.

I wonder if you can see what was sent by others

They’re being stored redundantly on a sqlite db. I’ll think about adding some kind of feed to the page if others are interested.

I don’t know, I kind of like having a place for some people to anonymously vent (as more than a few have).

This is really cool! I sent you an (hopefully) uplifting message for the week’s end. I know I shouldn’t but I really want to buy a receipt printer now!

They are well within the impulse buy zone, and it’s really easy to programmatically use with Python. Do it!

I have wanted to do experiments with a receipt printer hooked up to a Raspberry Pi, with some simple controls... but every time I look up the cost of the printer I balk. It's probably not fair, but I guess in my head it feels like they should be cheaper. Or at least the cost then makes me question how much time I'm really ready to put into stuff like debugging the printer drivers and putting together a case, etc etc.

The thing I actually want to play with is probably some kind of board game that incorporates the printer... ideally with bar/QR codes so the computer can print out money, IOUs, instructions, etc., and have this computer mediation that still gives people physical items to manipulate.

I'd love to see others!

this one time when i was young and dumb and into smoking weed, i remember running out of rolling paper so i rolled a joint using a supermarket receipt i had and smoked it

this was like 20 years ago, still makes me shudder after i learned about the BPA stuff

While not an outright solution to the fact that they _are_ expensive, if you don't care about them being second hand or a little older you can score a pretty good deal on sites like eBay.

For instance, TM-T88V printers can do more but cost around 3x as much as the one I got, a TM-T88IV which is the older version. Not perfect, but beats the like $200 price tag brand new.
