Hi All,
I'm developping a Point Of Sale since some days.I Solved the printing part and now i want to do a print preview of my ticket before printing.I tried a Label but it seems not to imterprete correctly see the preview below.My question is : Is there a tool here to realize this ?Or something that can be wrapped ?
