MQTT Labelmaker

Print labels from MQTT input using predefined pdfmake templates.

Setup

Config file

Before running, provide a config.json file in the root directory.

• credentials: MQTT connection settings as taken by the mqtt library on connect.
• base_topic: The root topic to listen on. Will try to match any subtopic against the given templates.
• printer: The name of the printer to use as given by lpstat -p..
• printer_options: Any additional printer options to pass with the print job. For supported values run lpoptions -p Printer_Name -l

Templates

Put your templates in the /templates subfolder. Each template consists of one javascript file, that should expose a async function render(input) that returns a pdfmake document definition.
