Selects the model for QR Code.
QR Code: Set the size of module
ASCII: GS ( k pL pH cn fn n
Hexadecimal:
1D 28 6B pL pH cn fn n
Decimal:
29 40 107 pL pH cn fn n
Values of pL,
pH:
pL, pH specify (pL + pH îî256) as the number
of bytes after pH (cn, fn, and [parameters]). (pL +
pH îî256) = 4 So (pL = 4, pH = 0)
Value of cn:
49
Value of fn:
67
Value of n:
1-16
Default n:
4
Sets the size of the module for QR Code as n dots. User must secure the quiet zone (left,
right, upward, and downward space areas defined by the QR Code symbol specifications) for QR
Code printing. Quiet zone is defined as 4 cells in standard and MicroQR code versions.
Notes:
The recommended module size is 4 dots and over. But, if use n = 4, this printer cannot
print maximum data barcode because the barcode width will be over the printable width.
So, Default value of n is defined to 3 in this version.
QR Code: Select the error correction level
ASCII: GS ( k pL pH cn fn n
Hexadecimal:
1D 28 6B pL pH cn fn n
Decimal:
29 40 107 pL pH cn fn n
Values of pL,
pH:
pL, pH specify (pL + pH îî256) as the number
of bytes after pH (cn, fn, and [parameters]). (pL +
pH îî256) = 3 So (pL = 3, pH = 0)
Value of cn:
49
Value of fn:
69
Value of n:
48 = Select error correction level L 7 %
49 = Select error correction level M 15 %
50 = Select error correction level Q 25 %
51 = Select error correction level H 30 %
