Just updated my Mid-2009 Macbook Pro running version 8.4.1.1803 of the Label software to OS X ML. Plugged in my LabelWriter 450 Twin Turbo and it appeared in Printers & Fax. Fired up the software and then printed out a label. So for me, it worked the first time straight away.
Since this label writer is plugged in to my iMac running Lion, I decided to share it via System Preferences. I was able to print from Mountain Lion Dymo Label software to the shared label writer connected to my iMac.
Bravo!
