Intercharacter Gap Size
Parameter # F0h, 7Dh
The Code 39 and Codabar symbologies have an intercharacter gap that is typically quite small. Due to various
bar code-printing technologies, this gap can grow larger than the maximum size allowed, preventing the digital
imager scanner from decoding the symbol. If this problem occurs, scan the Large Intercharacter Gaps
parameter to tolerate these out-of-specification bar codes.
