I've tried ESC_POS_USB_NET and it works great. My epson TM-T20III is configured to work on COM4 and test print works fine. Example from readme does not work at all. Here are screenshots of printer config. Any idea where to look?

epson printer device settings epson printer settings epson virtual port com

if you go to the command line and send some text to the COM port, does that work? Something like

C:\>  DIR > COM4

Hi. I am experiencing the same issue, also on TM-T20III but on COM5 port. When I do: echo abcd > \\.\COM5 My printer prints the text, I have also configured it to work with the python-escpos library and there it works just fine
