Single tool `print(markdown, title?, timestamp?, qr_urls?, cut?)`. Hand-rolled line-by-line markdown parser translates headings/bold/code/lists/blockquotes/ HR/links to ESC/POS, then sends raw bytes via TCP to 192.168.0.184:9100. Mirrors mcp-gemma4 layout (stdio server, single server.py, mcp package).

What is this?
An MCP server that exposes the Epson TM-m30 receipt printer (192.168.0.184) as a single tool to any Claude Code session. Claude calls print with a markdown string, the server translates markdown → ESC/POS and sends raw bytes over TCP to the printer.
Problem it solves
When working with Claude on the homelab box, useful output sometimes belongs on paper — a code snippet to keep at the desk, a quick summary, a TODO list, a QR for a URL. Currently this requires writing a one-off Python script that imports escpos and socket. With this MCP, Claude just says "let me print that" and it comes out of the printer with no extra plumbing.
Constraints / preferences
- Python (matches existing
mcp-gemma4pattern in this repo). - stdio transport (matches existing pattern; local-only invocation, no network exposure of the MCP itself).
- Single tool, minimal surface — markdown in, paper out.
- Mirrors conventions documented in
~/bin/POS_PRINT.md(Font B, 57 cols, native QR, TCP to192.168.0.184:9100).
