Show HN: Typos – Render Typst Documents to Thermal Printers (Go and ESC/POS)

I built typos because handling CJK fonts (Korean in my case) natively on thermal printers using standard ESC/POS code pages was pretty terrible.

Instead of messing with internal fonts, I've decided to write a simple script that can do Typst -> Image -> Print.

It features CLI, an optional REST server with async job queue and with template support.

The core Go CLI and printer logic are 100% hand-written. I experimented with AI tools via Opencode to write the REST API once the core logic was done (detailed full disclosure in the README), which is entirely optional.

Happy to take feedback, especially regarding code quality, or answer questions!
