I have C# who communicate with dot matrix printer on LPT1 port. I want to send control codes on the printer, but when I am sending the codes, printer is not responding, it answers only when I send FF code. I want to send this code ESC EM 82, but I don't know how to format it, FF I am sending hex format, also and ESC EM I am sending in hex format, but still printer is not responding. Which way is correct for using ESC EM 82 code in C#?
