I'm developing a POS system and I need to do coupon printing! I am in possession of a non-fiscal printer from the i7 elgin model. I've been looking for a way to print a coupon from a Report (.rdlc) that I've been working on for a while, but I can never print it, the impression gives error (there are no details about what the error is). I've already looked for API, .DLL on Elgin's website and nothing too ... I've tried countless ways and nothing works !! Does anyone have any solutions to make that impression?
PS: using the ElginUtility program I have already been able to print, but it's just test papers. Using PosPrinterTester also with you. What I want is that my program can also get it, which for some reason does not work!
