Is there any way that the print out in the thermal paper would adjust to fit the details in the receipt? As the option to make it small and putting 0 margins on both side wont work and still giving margins on the Receipt printed out. How to fit the details on the receipt? And how to fixed it. The software are really good. Buth printing out on the Receipt was giving a bit of a headache Thanks, SARRYSON
