Delimiters
A bar code delimiter is a character or control function that tells the printer where one bar code symbol ends and
an adjacent symbol begins. Different bar code styles accept different delimiters, which might be spaces,
commas, asterisks, horizontal tabs, or horizontal position-relative commands. Valid delimiters for the various
styles are listed in the Bar Code Style Characteristics section.
There is always a minimum one-fourth inch of white space called the quiet zone on either side of a bar code
symbol, so there is always an irreducible half-inch space between adjacent symbols, no matter which delimiter is
used. The space character occupies an additional tenth of an inch. Neither the comma nor the asterisk imposes
any additional space between symbols. Asterisks are valid delimiters in Code 3 of 9 (style 4) only, and are
normally used in pairs.
