Symbology

Description

EAN

The European Article Numbering system (abbreviated as EAN) is a
numeric superset of UPC. EAN has both a version that uses 8 digits
and a version that uses 13 digits. The version with 13 digits encodes
the same number of bars as 12 digit UPC Version A, but the 13th digit
is encoded into a parity pattern at the left of the center guard bar.

Interleaved
2 of 5

Interleaved 2 of 5 is a high density, self-checking, continuous numeric
symbology, which has mainly been used in the distribution industry.
Interleaved 2 of 5 actually encodes two digits, one in the bars and one
in the spaces.

POSTNET

The Postal Numeric Encoding Technique (POSTNET) uses binary
digits, represented as full bars and half bars, to provide a numeric bar
code symbology that is easily read and decoded by optical reading
systems. POSTNET provides both error detection and correction
capabilities.

HIBC 128

See the IPL Programming Reference Manual for a complete list.

UPC

Universal Product Code (UPC) is a subset of EAN. It is a fixed length,
numeric, continuous symbology employing four element widths. Two
common types of UPC are Version A, which encodes 12 digits, and
Version E, which encodes 6 digits. UPC has been used in the
supermarket industry since 1973. UPC supplemental code is intended
for only periodical issue numbers.

2D Symbologies

2D symbologies provide a more efficient way of encoding data than
standard bar code symbologies. 2D symbologies use two dimensions to
hold data instead of one, allowing much more information to be stored in
a smaller amount of space. Your printer provides the capability for printing
both stacked and matrix 2D symbologies.

2D Stacked Symbologies

2D stacked symbologies consist of short linear segments stacked on top of
each other. In addition to being able to condense a large amount of
information into the stacked format, PDF417 provides an extensive error
detection and correction option. Up to 510 characters can be recovered if
they are lost due to an error in scanning or if the label is damaged. 2D
stacked symbologies can be scanned with a laser scanner or imaging device
that features 2D code scanning capability.

Description

Code 16K

Introduced in 1988, Code 16K is an alphanumeric symbology similar
to Code 49 in that it employs multiple rows (from 2 to 16). Each row
is fixed length and uses a mirror image of the Code 128 coding
patterns.
