QR Code: Set the size of module

This command sets the size of the module for QR Code as n dots. The 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.

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 × 256) as the number of bytes after pH (cn, fn, and [parameters]). (pL + pH × 256) = 3 So (pL = 4, pH = 0)
Value of cn	49
Value of fn	67
Range of n	1-16
Default	4

Note: The recommended module size is 4 dots and over. But if n = 4, this printer cannot print maximum data bar code because the bar code width will be over the printable width. So, the default value of n is defined to 3 in this version.
