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 4400 printer provides the capability for printing both
stacked and matrix 2D symbologies.

2D Stacked Symbologies

2D stacked symbologies (such as PDF 417, Code 16K, and Code 49) 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, PDF 417
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.

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.
<SUB> 1 is used to represent the Function 1 character in 86XX emulation
mode. In advanced mode, the Function 1 character is represented by entering
<SUB><SUB> 1. The characters for Functions 2, 3, and 4 are represented in the
same way.
If you want to produce a square symbol, specify a height magnification of 1 in
advanced mode.

Code 49

Code 49 is an alphanumeric symbology developed in 1987 as a means of
labeling very small objects. A Code 49 bar code contains from two to eight
adjacent rows, each separated by a one-module separator bar.
In emulation mode, <SUB> 1 is used to represent the Function 1 character. In
advanced mode, <SUB><SUB> 1 is used to represent the Function 1 character.
The characters for Functions 2 and 3 are represented in the same way.
If you want to produce a square symbol, specify a height magnification of 2 in
advanced mode. A square symbol is specified by a height magnification of 250
in emulation mode.
Only alphanumeric (0) and numeric (2) modes are supported.
