based on the number of vertical symbol columns and the number of all data code words. At this time, if the number of
horizontal code words exceeds 30, add some vertical columns and obtain the number of horizontal code words again.
Repeat this procedure until all code words fall into place. If the number of vertical columns exceeds 90, the data will be
treated as an error and will not be printed.

● n: QR specification
n = Fixed at 01h
● a:Division function. Prints the QR Division code at maximum of 16 units
a=00h:Default value-Division function unavailable
01h:Division function available
● c: Code number. Ignored when the division function is not used. Specifies the code number for dividing.
c = Upper 4 bits: Specify the code number from 1 to 16 (00h to 0Fh)
Lower 4 bits: Specify the dividing number from 1 to 16 (00h to 0Fh)
Example) When the code number is 1 and the dividing number is 2: c = 01h
When the code number is 12 and the dividing number is 15: c = BEh
● p: Parity data. Ignored when the division function is not used. Functions as XOR value of all data.
● m: Model number
m-00h: Model 1
01h: Model 2
● e:Error correction level
e=00h: High density level [L] -Default value
01h: Standard level [M]
02h:
Reliable level [Q]
03h: Highly
reliable level [H]
● k: Mask number
k=00h to 07h: Mask 0 to 7
08h: No mask
09h: Auto selection -Default
● i: Data input mode
i=00h:Auto setting mode
01h: Manual mode
● Specifying data at Auto setting mode: The following manual mode data (numbers, alphanumeric characters, binary data,
and KANJI characters) can be specified freely. Add a NUL code (00h) at the end of data to indicate termination.
● Specifying data at Manual mode: 'Character mode + data + NUL' of 's' units can be specified as a block of character-
string data.
● t: Character code mode
t = N (4Eh): Numbers and ASCII numbers 0 to 9 are supported.
A(41h):Alphanumeric characters 0 to 9, A-Z, space, $, %, *, +, −, /, :
B(42h): Binary 4 byte size character(n)+ (data) n
