3-18-21 UPDATE DYMO Support has released a new DYMO Connect update and new DYMO Label update that fixes the blank label printing issues. In order to run the latest software update, open DYMO Connect, click "Help" > "Check For Updates" and download the latest version (188.8.131.52). For the latest DYMO Label update, download DYMO Label 8.7.4 here. These DYMO updates work with both pre/post Windows 10 update (in case you already rolled back the last Windows update), as well as with/without the optional Windows update from March 17th. Once the latest Connect version is installed, you should be able to print Dymo compatible labels with your DYMO LabelWriter Printer.
For DYMO XTL issues with DYMO ID, there is currently not a permanent update or fix to DYMO ID. Please follow the instructions below for the temporary workaround.
