Scale

Connect a scale to your computer to print labels with automatically detected weight. Set up product grids to print with a single click.

The ▼ Setup and ▼ Automatic Print panels are expandable by clicking their header. At the bottom: scale controls (weight, tare, unit) and connection buttons.
