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).

Runs the same code path as the MCP `print` tool (build_receipt + send_bytes)

without spinning up an MCP server. Prints one self-documenting page covering
|
|
every supported markdown feature plus a QR code.

|
## Self test
|
|
|
|
This page exercises every supported markdown feature. If anything here looks
|
|
broken on the printout, the parser has a bug.
|
|
|
|
### Inline formatting
|
|
|
|
Plain text. **Bold text**. `inline code`. A [link to example](https://example.com)
|
|
that gets rendered as text + url in parens. Mixed: this **bold spans `inline
|
|
code` and continues** after the code.
|
|
|
|
### Lists
|
|
|
|
- First bullet, short.
|
|
- Second bullet that runs long enough to wrap onto a continuation line so we
|
|
can verify the hanging indent works as expected at 57 columns.
|
|
- Third bullet with **bold** and `code`.
|
|
|
|
1. Numbered one.
|
|
2. Numbered two with a longer body that exercises hanging-indent for the
|
|
numbered variant which has a different prefix width.
|
|
3. Numbered three.
|
|
|
|
### Blockquote
|
|
|
|
> Single-line quote.
|
|
|
|
> Long quote that needs to wrap. The pipe prefix should appear on the first
|
|
> line; continuation lines indent under the text, not under the pipe.
|
|
|
|
### Horizontal rule
|
|
|
|
---
|
|
|
|
### Code block
|
|
|
|
```
|
|
def hello(name):
|
|
print(f"hi, {name}")
|
|
return 42
|
|
```
|
|
|
|
### Long line
|
|
|
|
This is a single very long paragraph line that should soft-wrap at the 57
|
|
column boundary determined by Font B on 80mm thermal paper, demonstrating
|
|
that the wrap algorithm prefers word boundaries over hard breaks.
|
|
|
|
### End
|
|
|
|
If all of the above rendered correctly you are good to go.
