Large Intercharacter Gap (Code 39)
Definition: When enabled, the scanner can read symbols with gaps between bar
code characters that exceed three times (3x) the narrow element
width.
Usage: Large Intercharacter Gap is helpful for reading symbols that are
printed out of specification.
Caution: Do not use Large Intercharacter Gap with Narrow Mar-
gins enabled since a large intercharacter gap (over 3x) could cause a
narrow margins (5x) to be interpreted as an intercharacter gap.

Fixed Code Length (Code 39)
Definition: Specifies the exact number of characters that the scanner will recognize
(this does not include start and stop and check digit characters). The
scanner ignores any code not having the specified length.
Usage: Fixed Code Length helps prevent truncations and increases data
integrity by ensuring that only one label length will be accepted.
