Print Chinese Garbled! about node-thermal-printer HOT 4 CLOSED

Hi, your printer needs to support Chinese character.

from node-thermal-printer.

I want to print chinese but print out the Garbled.
English Is OK.

this is my code:

var printers = require("node-thermal-printer");
printers.init({
type: 'epson',
interface: 'printer:' + printer.getPrinters()[0].name,
characterSet:'CHINA'
});
printers.alignCenter();
printers.println(iconv.encode('--------测试打印----------','GBK'));
printers.println(iconv.encode('--------测试打印----------','UTF-8'));
printers.println('--------测试打印----------');
printers.println('hello');

printers.execute( function(err){
console.dir(err);
});

Hi,

Did you resolve the problem? I have the same problem, and I pretty sure that my printer char code setting is Chinese(BIG5).

I modified the source code need a iconv-lite module
add code to node-thermal-printer/lib/core.js

   var fs = require('fs'),
    net = require("net"),
    PNG = require('pngjs').PNG,
    star = require('./star'),
    epson = require('./epson'),
    getInterface = require("../interfaces"),
    iconv = require('iconv-lite');

and println:function(){}

  println: function(text,isGbk){
    if(isGbk){
      append(iconv.encode(text,'GBK'))
    }else{
      append(text.toString());
    }
    append("\n");
  },

used

 var printer = require("node-thermal-printer");
 printer.init({
		  type: 'epson',
		  interface: printname,
		});
printer.println('测试打印中文',true);

Hi,
Thank you very much for your replay.

Which printer did you use? I tried on POS-8220, and set the charset to GB18030, and it still print mess code.

I'm wondering it is caused by printer.

Do you have any other idea which could resolve the mess code problem?

Thanks you very much.
