While installing the Dymo printer on your Mac device, you may encounter some problems with the web service. You can follow the steps in this document to install the web service successfully.
Once the web service is in place, it is essential that you conduct a test print for the setup to work seamlessly. To do this, open the Dymo web service and click Print for a test badge.
Note that this step is outside of the Visitor web app, and you need to run a test in the Visitor web app once your setup is complete.
