Thanks in advance to all for your valuable time !

I have to print a ZPL image using printer , What I have done so far is Uploading the Image and converting it to the ZPL string
but now I want to send it to the printer that is on my usb using asp.net C# code , I have read the ~DG command is useful for the same , But still dont know how to use this command to save the image in the printer memory .
