使用Cordova的iOS中包含来自iOS的阿拉伯文本的ZPL内容打印到IMZ320

Question

我正在使用Cordova开发混合应用程序。我能够在Android版本中使用阿拉伯文本打印ZPL内容。但是相同的ZPL代码在iOS版本中不起作用。打印机获取信号，蓝光闪烁。但是，当内容具有阿拉伯语文本时，没有打印。

我正在使用Zebra IMZ320打印机。您能否与iOS的阿拉伯语内容分享一个工作示例。

var TestPrint = "^XA^FO50,50^A@E:TT0003M_.TTF,N,50,50^FD"+"الفئة الرابعة عشر"+"^FS ^XZ";
//-- "ÙحاÙÙØ©"
localStorage.iosConnected_ZebraPrinter_Name = 'XXXXJ142401535';
window.plugins.CordovaPrinter.print(
    function (success) { // Call the print method
        console.log('Platform : ios, Successfully printed...'
                   + 'n thru. ',localStorage.iosConnected_ZebraPrinter_Name);
        },
    function error(err) {
        console.log('Error Printing to ' + localStorage.iosConnected_ZebraPrinter_Name);
        console.log(err);
    },
    localStorage.iosConnected_ZebraPrinter_Name, //serialArray[0],
    TestPrint);

挣扎了一个多月后，最终找到了解决问题的解决方案，如下所示：

//-ARABIC TEXT ENCODING - FOR IOS---------------------------
/*-----String to utf-8 encoded hex-----*/
function toHex(str,hex){
  try{
    //We have appended '-', because, you need to prefix the utf-8 hex code with an underscore, to be printed in ZPL
    hex = '_' + unescape(encodeURIComponent(str))
    .split('').map(function(v){
      return v.charCodeAt(0).toString(16)
    }).join('_')
  }
  catch(e){
    hex = str
    console.log('invalid text input: ' + str)
  }
  return hex
}
//-EXAMPLE : console.log('toHex of ' + str + ' is : ' + toHex(str, 16));
//----------------------------------------------------------
var TestPrint = "^XA" +
"^LH100,150" +
"^CWT,E:TT0003M_.FNT" +
"^CFT,30,30" +
"^CI28" +
"^FT0,0^FH^FDTesting 1 2 3...^FS" + 
"^FT0,50^FH^FD" +toHex(str, 16)+ "^FS" +
"^FT0,100^B3^FDAAA001^FS" +
"^XZ" ;
console.log('TestPrint : ', TestPrint);
localStorage.iosConnected_ZebraPrinter_Name = 'XXXXJ142401535';
window.plugins.CordovaPrinter.print(
    function (success) { // Call the print method
        console.log('Platform : ios, Successfully printed...'
                   + 'n thru.', localStorage.iosConnected_ZebraPrinter_Name);
        },
    function error(err) {
        console.log('Error Printing to ' + localStorage.iosConnected_ZebraPrinter_Name);
        console.log(err);
    },
    localStorage.iosConnected_ZebraPrinter_Name, //serialArray[0],
    TestPrint);
