I get the message No Dymo printer is installed?
What: Popup when you try to print a label
Cause 1: You do not actually have a Dymo printer
Cause 2: Dymo Connect (DCS) needs to be updated or installed
Cause 3: Dymo Label Web Service is not running
Solution: Purchase and install a Dymo label printer. Install the Dymo Connect (DCS) software
The service supports all Dymo desktop printers (not handheld models). The service does not support label printers from other manufacturers.
Open Dymo Connect -> Help -> Check for updates
If an update is downloaded, you should restart the PC after installation
