Generates a check digit when “?” is in the barcode data.
The position of “?” is irrelevant as long as it is within the barcode data.
With POSTNET, CODE93, UPC/EAN EXTENSION, CODE128 and GS1-128(UCC/EAN-128), no
check digit is generated.
If “?” is inserted, it is treated as barcode data.
With only UPC/EAN EXTENSION, the data is printed above the barcode.
