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

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
