Set data parsing mode for QR Code
ASCII
Hexadecimal
Decimal
Value of n:
GS ( k ETX NUL 1 D m
1D 28 6B 03 00 31 44 m
29 40 107 3 49 68 m
30h = Manual Mode
31h = Auto Mode (default)
Default:
03h
This command specifies which method of data parsing to use. Auto mode will try to determine the
best encoding scheme to use to encode the data based off of the values in the buffer. This mode
may not encode the data as desired (data intended to be encoded as one type may be encoded as
another due to overlap between the two).
Manual mode allows for more control, as the data can be broken into blocks (up to 200) that are
each assigned a type using a leading byte, with each block separated by a comma (0x2C). See store
symbol data for QR Code for more details.

Note: QR code employs Reed-Solomon error correction to generate a series of error correction
code words.
Store symbol data for QR Code
ASCII
Hexadecimal
Decimal
GS ( k qL qH 1 P 0 f1 . . . fk
1D 28 6B qL qH 31 50 30 f1….fk
29 40 107 qL qH 49 80 48 f1 . . . fk
This command stores the QR code symbol data (f1... fk) in the symbol storage area, which is
located in RAM in font memory (command is ignored if no memory is free).
qL and qH: 04h < (qL+ qH x 100h) < 1BB4; 0h < qL < FF; 0h < qH < 1B
f: 0h < f < FF
k = (qL + qH x 100h) – 03h
Note:
k bytes of f1…fk are processed as symbol data.
when using manual mode, data size must also account for the leading type byte, the delimiters
(0x2C), and any headers (if using binary blocks)
