Symbology - Intercharacter Gap
The Code 39 and Codabar symbologies have an intercharacter gap that is customarily quite small. Due to various bar
code printing technologies, this gap may grow larger than the maximum size allowed, causing the scanner to be unable
to decode the symbol. If this problem is encountered, scan Large Intercharacter Gaps to tolerate out-of-specification
bar codes.
