2D Bar Code – Aztec Specific Options
Description Use this command to print an Aztec two dimensional bar code symbol. The
symbols are square on a square grid with a square central bullseye finder. Data is encoded in a
series of “layers” that circle around the bullseye pattern. Each additional layer completely
surrounds the previous layer thus causing the symbol to grow in size as more data is encoded.
Supported Printer Models: G-Series, 2844*, 3842*
* - Available as a firmware download from the www.zebra.com website.
