8.1.11.5 GS1 Databar Limited
GS1 Databar Limited has the same data characteristics as the GS1 Databar Omni-
directional barcode, except that it may only include values up to 4 trillion. This symbology is
specifically designed to be read by wands and handheld laser scanners. Omni-directional
scanners can not read it efficiently.

8.1.11.6 GS1 Databar Expanded
GS1 Databar Expanded is a variable length symbology capable of encoding up to 74
numeric or 41 alphabetic characters. This symbology does allow for the linkage flag, which
determines if there is a 2D composite barcode associated with the linear barcode. Despite
the possible length of the symbol, it can still be omni directionally read by suitably
programmed laser point-of-sale scanners because the symbol can be decode in up to 22
segments and then reconstructed.

8.1.11.7 How to Print an GS1 Databar Barcode
There are two steps to printing an GS1 Databar barcode:
1) Send the ^D114 command and the 7 setup parameters
2) Send a label format that calls the GS1 Databar barcode TCI #35.
These are the 7 parameters that MUST follow the ^D114 command:
1) Type of GS1 Databar barcode
2) Multiplier
3) Segments per row
4) X undercut
5) Y undercut
6) Separator Height
7) Data to be encoded
