This is a very simple web interface to create text labels on a Brother QL series label printers supported by pklaus/brother_ql.

Create a virtual environment and install the requirements

$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip install -r requirements.txt

Start the server by providing the model and connection string as in the following example:

$ ./app.py --model QL-500 tcp://192.168.1.1:9100

Run app.py -h for more info.

Open your browser on the shown URL (defaults to http://127.0.0.1:8013/). The application uses modern JavaScript (promises, blobs, etc) and requires a modern browser. It was tested with Chrome only, but probably works in Firefox, too.

Labels are based on HTML templates located in the static/labels/ directory. Templates need to start with a supported label size followed by an underscore. See pklaus/brother_ql for a list of supported sizes.

The templates need to contain exactly one root element, specifying the exact size of the label in pixels (again, check the above site for proper values).

Elements containing an input class can be edited through the form.

Divs with the qrcode class will be converted to a QR Code. They also need the input class and a data-value attribute instead of an inner text.

Please feel free to submit feedback in the form of pull requests.
