How can I send raw ESC commands and read printer status replies to a USB printer like Epson TM-T88V? Maybe I'm looking for dll or windows sdk. Please consider that I'm looking for an SDK for NON-intelligent printers so ePos SDK is not suitable.
Now I can printer and read printer status using an Epson tool that converts an USB printer port to a virtual serial port. Is this the only way to communicate with these USB printers?
