Joscha 4e82a51212 Fix line spacing 
The characters should touch each other horizontally and vertically. That
way, things like half-height block character based QR codes look correct
instead of seeming stretched.

Displaying pixel-perfect images on esoteric devices.

Developing

After cloning the repo, run meta/build-all once. Some parts of the project use files from other parts of the project (e.g. the thermal printer includes the typst plugin wasm file in its binary). The build script produces these intermediate artifacts.

Thermal printer ideas

  • Appointments, tasks for the day
  • Business card that looks like a receipt
  • Commit history (maybe across repos)
  • Emails (live)
  • HN front page
  • Issues on a GitHub repo (like tickets - "when your number is called, ...")
  • Large image using multiple strips
  • Live graph (a new row of pixels every few seconds)
  • Measuring tape
  • Personal finances in the form of a receipt
  • QR codes
  • Quote (fortune, maybe cowsay)
  • RSS feeds (live?)
  • SSH login attempts (live)
  • Stats in the form of a receipt
  • Sudoku
  • Sunrise, sunset
  • Text banner (text flows parallel to paper)
  • Weather report
  • Wiki To Go
  • Xkcd (current, random)

Implemented:

  • Calendar
  • Cellular automaton (1D)
  • Chat messages (euph, twitch)
  • Instant camera
  • Procedural easter egg generator

Todos

  • Sensible limits on all string inputs
  • Better debug logging
