^BQ
QR Code Bar Code
Description: The ^BQ command produces a matrix symbology consisting of an
array of nominally square modules arranged in an overall square pattern. A unique
pattern at three of the symbol’s four corners assists in determining bar code size,
position, and inclination.
A wide range of symbol sizes is possible along with four levels of error correction.
User-specified module dimensions provide a wide variety of symbol production
techniques.
QR Code Model 1 is the original specification, while QR Code Model 2 is an
enhanced form of the symbology. Model 2 provides additional features and can be
automatically differentiated from Model 1.
Model 2 is the recommended model and should normally be used.
This bar code is printed using field data specified in a subsequent ^FD stream.
Encodable character sets include numeric data, alphanumeric data, 8-bit byte data,
and Kanji characters.
