GLM Barcode - Data Matrix

Dear Experts,

This is about Data Matrix Barcode in Label.

I do have adopted following code

<02GCG_CHARG[B:DM,UNIT=0,COL=20.000,DMODE=1,SSIZE=24,STYPE=0,RESX=1000.000,RESY=1000.000]>

I am getting the desired output but it is very small in size as shown below,

then i have altered couple of parameters of above code ( e.g. SSIZE etc..)  but then getting different result as shown below,

If i am not mistaken, the same code is getting repeated 24 times in 6x6 grid...

My requirement is that, i want just single barcode ( QR code ) in BIG size say.. 1 CM X 1CM...

can you please guide me which parameter of code i should alter or what code i should write for the same..

Kindly Advise.

Thanking You

Regards

Amol
