Hi Kamilla,

I think at this point this would be better discussed on the mailing list to
figure out if this is a configuration issue or a bug and to make use of the
experience of many more Koha users. 

I could imagine various things going wrong:

- Could the barcode labels be cut off on the left on the printout?
- Do other barcode types print correctly?
- Could it be that the check digit (Prüfziffer) is not read? Some scanners can
be programmed with different settings for reading barcodes, including different
handling of the check digit.
- Are you using AutoBarcode with the EAN13 options to generate the numbers in
the first place? Or reading them from the books?

Include as much information as you can, like your exact Koha version and which
config settings were used for generating barcodes and the labels. Maybe also
some sample numbers?
