Bar Code Printing on the LA600 MultiPrinter
20.6 Bar Code Characteristics
20.6.4 Intercharacter Gap
The intercharacter gap separates the last bar in one character from the first
bar of the next. The intercharacter gap is required in styles where each
character begins and ends with a dark bar.
20.6.5 Number of Characters in a Bar Code
The number of characters that form the bar code varies among the bar code
styles. While some styles specify the number of characters for a bar code
structure, others use character symbols of variable length.
While there is no standard number of characters for bar codes among the
various styles, each style does specify a maximum data length, and data
exceeding it are truncated. Exceeding the maximum data length in POSTNET,
EAN 8, EAN 13, UPC A, and UPC E causes the LA600 MultiPrinter to ignore
the bar code sequence.
20.6.6 Check Digits
Check digits, or ‘‘checksums’’, are supported by the LA600 MultiPrinter.
For the POSTNET and Code 128 bar code styles, the printer automatically
computes the check digits and embeds them at the end of the bar code symbols.
