I am attempting to create labels with barcodes that will encode the product code and lot number respectively. We have an existing system where, using Zebra Programming Language ZPL font, we can enter "$P" to encode the product code, or "@@272" to encode lot numbers. For the new labels I am creating, entering the ZPL variable "$P" or "@@272" will correctly populate and print the numbers, however the barcodes are not encoding anything. I am instead printing barcodes that encode "$P", and "@@272", which is obviously not helpful.
Does anyone know why a barcode would fail to pull the info it needs, while other field on a label pull that info correctly?
