I was somewhat disappointed to find out that the old Lightscribe website doesn't work any more so I had a dig around on my system archives and found a couple of .deb packages which, after installation, seem to work perfectly.
You can download them from here:
Lightscribe
Lightscribe_Application
The utility gets installed to the following location on my Linux Mint 17 install:
/opt/lightscribeApplications/SimpleLabeler/SimpleLabeler
When used with the K3b application to burn the DVD/CD, it all works perfectly.
