MTG Proxy Printer

A local Magic: The Gathering proxy printer. Search Scryfall, build a print queue, see card price estimates, and print front-face proxies to an ESC/POS network printer.

Features

• Scryfall card search, card-name lists, and Scryfall URLs
• Direct Scryfall card previews with lightweight UI thumbnails
• Per-card USD prices, discount display, and a $0.00 print total
• Queue editing with duplicate cards preserved
• Fixed-size card rendering and sequential ESC/POS printing
• Bun 1.4, SvelteKit, TypeScript, Sharp, and Canvas

Development

Requirements: Bun 1.4 and a reachable Scryfall connection.

bun install
bun run dev

Open http://localhost:5173.

Run verification:

bun run test
bun run build

Printer configuration

The default printer target is 10.0.1.128:9100. Override it with environment variables:

PRINTER_HOST=192.168.1.50 PRINTER_PORT=9100 bun run dev

Printing is server-side and requires the configured printer to be reachable from the machine running the app.

Docker

docker build -t mtg-proxy-printer .
docker run --rm -p 3000:3000 \
  -e PRINTER_HOST=192.168.1.50 \
  mtg-proxy-printer

Notes

• Price data comes from Scryfall and is an estimate, not a purchase quote.
• The app prints front-face proxies; double-faced cards use the first face.
• Do not expose the printer endpoint publicly without authentication and rate limiting.
