In the "Image to Terminal character" space this is also a known solution. Map characters to their shape and then pick the one with the lowest diff to the real chunk in the image. If you consider that you have a foreground and a background colour you can get a pretty close image in the terminal :D

Surprised you didn't include the output result for the test image as a showcase of the library's results.

Edit: nvm, confused by the libraries purpose. Thought it was primarily character based rendering focused based on the subject under discussion.

Thank you for posting my project :D

You can often times find them for really cheap on the secondary market. Like old ones from a restaurant. I got quite a few for very cheap over the years. One was 20$ for a 80mm one.

So maybe that's a low budget option to tinker for you? Or is the problem buying one at all?

Always happy to see other thermal printer projects :D

I have my own project for using these for TTRPGs: https://sales-and-dungeons.app/

Always stand up at 07:00 am. Take supplements against my migrains with a good amount of tap water. Eat the same oatmeal with some cacao powder and oat milk just to get some food in my system. Then I do about 45 - 60 min of Japanese language reviews. At 08:00 I sit down in my work area and start working. No coffee/caffeine.

This is how 90% of my workdays go for the last 1.5 years :)

That looks like a fun project to build!

I switched from Goland to Zed. Works really well. Only missing debugger support... After that it would be perfect for my usage :)

I tried to use zeds SSH remoting for a work project. Typescript with big codebase and sadly the performance is a rollercoaster. Types sometimes load so slow that it's unusable. VSCode remote doesn't seem to have this problem, although I'm not sure yet if it's really just a zed problem. I would need to try it with some more isolated use-case. Still happy to see the progress! I switched to zed for a lot of my private dev work already

The same project I'm working on since about 5 years. Using thermal printer as TTRPG utility :)

I researched thermal printers recently and your project came up. Very creative!

Thanks a lot! Thermal printer as DIY thingy are quite a niche, but they are very fun to play around with
