GS h n
[Name]
Select bar code height
[Type]
ASCII:
GS h n
Decimal:
29 104 n
Hex:
1D 68 n
[Scope]
1 ≤ n ≤ 255
[Explanation]
Select bar code height. And N is the number of dots on the vertical direction.
[Default]
n=48
[Example]
unsigned char str[4];
str[0] = 0x1D;
str[1] = 0x68;
str[2] = 30;
SendDataToPrinter(str,3);//Set the bar code height to 30 vertical dot pitch
