Valid from List & Label 4Starting with List & Label 12, the bar width for barcodes can be adjusted in the Designer.
For older versions, we recommend to use multiple overlapping barcode objects. Size the rectangle of the barcode objects in the Designer according to the desired bar width corresponding to the respective barcode content. Then assign an appearance condition that exclusively enables only one of these barcode objects depending on the character count of the barcode content string. At print time List & Label will use the appropriate barcode object depending on the actual contents and thus print with the required bar width.
