Generation Structure
The data input structure (hh...h) is as follows:
Auto Format (W1d)
With bar code identifier "d", the data begins after the last character of the column
position field, and does not include any command characters. The data string is
terminated with a termination character, usually a 0x0d hex that occurs twice in
succession. The bar code symbol will have the following characteristics:
1. Model 2
2. Error Correction Code Level = "M" (Standard Reliability Level)
3. Mask Selection = Automatic
4. Data Input Mode = Automatic
Example:

Appendix G – Bar Code Details
Rotation
W1 Fixed value, extended bar code set
Selects the QR bar code formatting mode, where:
D = Manual formatting. Allows the data string (hh...h) to
D and d
d = Automatic formatting. Allows the data string (hh...h)
Module size horizontal multiplier Each cell in the bar code is
square, therefore "c" and "d" must be equal. Depending on
the conversion mode (<STX>n or <STX>m), each unit
indicates a cell dimension of .01 inch or .1 mm.
Module size vertical multiplier. (See explanation for "c",
above.)
