If you can't type it, try another software. For example, if you can't type with lable-IV at first, switch to Label-I .. These two softwares are actually two versions of the same software. Label-I is the old version, and Label-IV is the new version. In the past, some barcodes were made of Label-I, which may not be typed with Label-IV. I don't know much. I wonder if I can still help you.
