The carrier is Trans-o-Flex. I need to send some sample labels to their IT department. They will check if the labels are readable by their scanners. But i am now confident, that this will work on their side also.

Note that you really only need one graphic image to work with - here's how to do it with a single invisible filled rectangle graphic (I kept the name "narrowB"). This takes a string of numbers and generates the intermediate string and bar code.
