DYMO Label TUI (dymo-bluetooth)

This is a tiny terminal UI that:

• lets you pick a font, font size, and text
• renders label.png (height = 30 px)
• runs a console preview via dymo-bluetooth
• optionally prints to the first discovered DYMO LetraTag LT-200B nearby

One command

python run.py

First run will:

• create a local virtual environment in .venv/
• install dymo-bluetooth and typing_extensions

Quick notes

• The DYMO LetraTag LT-200B printable height is 30 px, so this tool renders label.png at 30px tall.
• The upstream project recommends stretching the image by 2x to match how the mobile app prints.

Troubleshooting

• If no printer is found:
  • ensure the printer is on, close enough, and your OS Bluetooth is enabled.
  • on macOS, allow Bluetooth access for your terminal/Python if prompted.
  • try increasing timeout in label_tool/config.py.

Info

• Vibe coded it with AI, and used on macOS. going to pretty it up later on, but this will do for now.
