Works! Then reinstalled other local printers.

Opened Dymo Labelwriter software that now installed. Local printer (Dymo and another) disappeared from Printers and Scanners, so had to reinstall. Then a warning about Sanford LP wanting to access/change extensions, which I ignored. Many requests to access locations (presumably for the Office add-ins). But using 'control' and 'mouse click' then 'open' on the unpacked RichieBBB DYMO Label v.8.pkg icon allowed it to run. So I downloaded RichieBBB's driver patch (below) but get a fail to open because it's from an unidentified developer. They start install but fail with a message that it's not compatible with this version of my OS. Then I tried two drivers (8.0, 8.7.2-64bit) from Dymo. I added the Dymo 400 as a printer with default software first. The 3rd option on my Security & Privacy page (Anywhere) doesn't exist on Catalina. Those printers must be added through the Print Center/Printer Setup Utility.Just an install thread of what worked for me:

The exception is the LabelWriter Duo and the older 300 series printers. After the software installation is complete, just plug in a new printer and it will automatically install. More information is now provided about printing to shared printers and print servers over the network in the online Help. Theyre so simple to use, they are compatible with so many different label sizes, you get Dymos FREE DLS Software and you. The Add-in is automatically installed when you install DLS and you have Microsoft Office 2004 or X already installed. Dymo LabelWriter Printers connect to your PC or Mac (and now theres new WiFi models), and these labels printers enable to you print anything from Address and Shipping labels right through to Name Badges and Jewelry Labels. Printing to both the LabelWriter Duo Tape and Label printers at the same time is not recommended. You will not be able to locate a LabelWriter Duo printer with Rendezvous. The LabelWriter Duo printer does not support Rendezvous. The LabelWriter Duo printer appears as two separate printers: DYMO DUO Tape and DYMO DUO Label. When installing a LabelWriter Duo printer, select 'DYMO DUO USB' from the list of choices in the Printer List. DYMO is proud to present version 7 of DYMO Label Software! This new version now supports the expanded line of LabelWriter printers: LabelWriter 400 and 400 Turbo, LabelWriter Twin Turbo, and LabelWriter Duo.ĭLS now includes a Tape Editor for printing on D1 labels using our new LabelWriter Duo printer.
