M1 MacBook Air "Missing USB Class Driver" when trying to print to Dymo 4xl

I can print wirelessly to my Epson printer with no issues. I downloaded the latest Dymo USB driver 8.7.5 that is supposedly compatible with Big Sur.


I go through the installation and it seems to work fine. The Mac recognizes the Dymo 4xl printer in the print utility. When I try to print directly via a USB connection (no hub) the error message on the print dialog reads "Missing USB Class Driver" and nothing will print.


Here's what I have tried to so far to troubleshoot:


Reset the entire printer system

Rebooted after drive install

Deleted Dymo drive and tried reinstall.


Any help or insight would be GREATLY appreciated. Thank you!

I don't have this printer, so I can't replicate this nor can I test any possible solutions... BUT: This sounds like it might be related to the change in Big Sur that blocks Kernel Extensions that use USB or Networking.


There might be a workaround, though, by booting into Recovery (by holding down Power when starting up your M1 Mac and choosing Options), and then going into the Startup Security Utility and enabling “Allow user management of kernel extensions from identified developers” (all details available at https://support.apple.com/guide/mac-help/change-startup-disk-security-settings-a-mac-mchl768f7291/mac ).
