My LabelWriter 450 served me pretty well, but the smaller shipping label size was never adopted by anyone but paypal and I just wanted a printer that worked with the standard 4” X 6” shipping label.
I had to build and install the Dymo SDK with my last printer, but apparently since then Dymo has abandoned Linux and their driver installation is broken. I found a git repo with a repaired fork of the Dymo drivers and some updated instructions for the install:
sudo apt-get install git libcups2-dev libcupsimage2-dev gcc g++ automake cd ~/ git clone https://github.com/Kyle-Falconer/DYMO-SDK-for-Linux.git cd DYMO-SDK-for-Linux aclocal automake --add-missing autoconf ./configure make sudo make install
Once the drivers were installed all the templates showed up in glabels again and I was able to print labels again.
