Any idea how RMS is accessing various OPOS printers, like EPSON, Samsung etc.
I tried to access OPOS printers using Microsoft.PointofService.Dll (Application developed using VB.NET, and installed POSfor.NET 1.1 version). It worked fine for EPSON series, but is not working for Samsung SRP-350 series. But RMS is able to print to it. Can someone specify how RMS is accessing various OPOS printers?
