Research direction

Start by reproducing the issue through the escpos.USB device, escpos.Printer options, and the .text("สวัสดี") call shown in the report. Trace how the UTF8 encoding option reaches the printer and compare the emitted data with the printer's Thai character support. Done means Thai text prints as สวัสดี rather than Chinese characters, with a regression check if the project provides one.

Written by the indexing model from the issue text.

Description

I have tried UTF-8 to print the Thai characters but I got Chinese characters instead.

This is my code

const escpos = require("escpos");

escpos.USB = require("escpos-usb");

const device = new escpos.USB();

const options = { encoding: "UTF8" };

const printer = new escpos.Printer(device, options);

device.open(function (error) {
  printer
    .size(0, 0)
    .font("a")
    .align("ct")
    .style("b")
    .text("สวัสดี")
    .cut()
    .close();
});

This is the result

Expected result

Should print สวัสดี in the paper
