How to Verify Lister Connect is Running
Lister Connect is a background app that runs on your computer and is required for printing via Lister. If you are unable to print or import weights from scales using Lister, first check to see if the printer icon in the top right corner of Lister is green. If you've not installed Lister Connect on your computer, please follow this guide
If the printer icon is red, it means the connection between Lister and the Lister Connect app is not turned on. Continue to the next step "Unable to establish connection with printer" for steps to diagnose and fix
If the printer icon is GREEN, it means the connection is working. Click here for more troubleshooting steps if you are unable to print labels or import weights from scales to Lister
