3. LABEL FORMATTING
A label format consists of a header record and field records. These
records describe how the label is to be printed. The starting record
(record zero) is the header. The header contains information about
the label height, width, print speed, etc. The records following the
header are the field records. A field record contains information on
where the field starts on the label, type of characters or barcode to
use, etc.
