Here is a more detailed instruction on how to manually add items to the kmenu:
Click on the category you wish to place it in (graphics as it is a app that prints labels)
In the menu editor you need to hit the button that says "new item"
In the item name enter the name of the app and hit "ok"
when the item is added click on it and you will see four boxes
the one you need to go into is the "command" box and from there there is a small button that can pull up the folder navigator right next to it
from there go to the root folder and navigate to opt, then to lightscribeApplications, then to the SimpleLabeler sub folder and click on the simplelabeler file then hit "ok"
then make sure to save it before closing off the menu editor.
note: there are two things you needed to install with this one.
One is the LightScribe System Software and the other is LightScribe Simple Labeler
and you need both for this to work.
both can be obtained here:
