I'm having an issue printing QRCodes that have certain accented characters, such as "Ó". The printer I'm using simply renders a single T instead of the code, when these characters are used.
I've determined that the printer works fine if the data is encoded in ISO-8859-1 rather than UTF8. According to this StackOverflow thread, ISO-8859-1 should be the default, as UTF8 is only supported through an extension.

I would suggest changing:
https://github.com/mtmsuhail/ESC-POS-USB-NET/blob/2de903957145a6f564d9a9eda0612356dd19c6a5/ESC-POS-USB-NET/Epson%20Commands/QrCode.cs#L56
to
list.AddRange(Encoding.GetEncoding("ISO-8859-1").GetBytes(qrData));
That fixes the issue for me.
Thanks, Alex J.
