Suppress Check Digit for Code 39 & Codabar
The extra character that is added to the end of a barcode is called the
check digit or check character. For barcode symbologies that do not require
a check digit such as Code 39 and Codabar, the check character may be disabled
by setting the Add Check Digit property to "No". If the check digit
is to be encoded in the barcode, but not displayed, set the Add Check
Digit to Text to "No".
