d – 0H – FFH (binary data)
k - (xL+xH x256) – 3 (-3 for cn, fn and m)
[DESCRIPTION] Stores QR code data (d1 … dk) in QR code m area.
[CAUTION] * Highest supported QR level is 19. Max result QR size is 93x93 modules (QR pixels). Max
input data is 1903 digits (‘0’ – ‘9’), or 1153 alphanumeric chars, or 792 binary bytes, or
488 Kanji chars.
* If k > 1903, all data is dropped and no QR is printed.
* All QR data starting with m + 1 are cleared.
