Symbologies 12 - 89
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
imager from decoding the symbol. If this problem occurs, scan the
Large Intercharacter Gaps
parameter to
tolerate these out-of-specification bar codes.
