I need to print invoices in Vietnamese. I looked for some solutions but in the end, I found that the printer does not support Vietnamese. Do you have any solution for this? How can I print in Vietnamese?

You can sendRawData turn off Chinese Character and set codepage VN.

But i have a problem with this. This is Lý Chính Thắng change to Lã Ch anh Th ương

How can I do this? Can you give me more detail to do this?

    const VIE_LANGUAGE = '\x1b\x74\x27'; //x27 => codePage VN in model printer, you can replace it
    const CHINESE_OFF = '\x1c\x2e';
    const SET_INTERNATIONAL_CHARACTER = '\x1b\x52\x12';

    NetPrinter.printText(
      `${CHINESE_OFF}${VIE_LANGUAGE}${SET_INTERNATIONAL_CHARACTER}${BOLD_ON}(Đơn tạm tính)${BOLD_OFF}`,
    );
    
    
    You can try.

Thank you for supporting me.
Where did you get the codePage? My printer is a KPOS zy307. It seems that codePage is not working with my printer.

Hello guys. After some time searching, I found that my printer can't print the Vietnamese language. So I'm using image printing instead of text printing :D
