Set QR code data

ASCII GS ( k qL qH 1 P 0 f1 . . . fk
Hexadecimal
1D 28 6B qL qH 31 50 30 f1....fk
Decimal

This command stores the QR code symbol data (f1... fk) in the symbol storage area.
qL and qH:
f: 0h < f < FF
k = (qL + qH x 100h) – 03h
Note:
• k bytes of f1...fk are processed as symbol data.
• It is possible to encode to a QR code as follows. Be sure not to include anything except the following in the
f1...fk data:
Category of data
Numerical Mode data
Alphanumeric Mode data
Kanji Mode data
8-bit Byte Mode data
