    1P0https://qz.io 1A11C 1E0
  

• printer print this single line only. how to solve this?

  var config = qz.configs.create("POS-80", { encoding: 'ISO-8859-1' });

   // The QR data
   var qr = 'https://qz.io';
  
   // The dot size of the QR code
   var dots = '\x09';
  
   // Some proprietary size calculation
   var qrLength = qr.length + 3;
   var size1 =  String.fromCharCode(qrLength % 256);
   var size0 = String.fromCharCode(Math.floor(qrLength / 256));
  
   var data = [ 
      // <!-- BEGIN QR DATA -->
      '\x1D' + '\x28' + '\x6B' + '\x04' + '\x00' + '\x31' + '\x41' + '\x32' + '\x00',    // <Function 165> select the model (model 2 is widely supported)
      '\x1D' + '\x28' + '\x6B' + '\x03' + '\x00' + '\x31' + '\x43' + dots,               // <Function 167> set the size of the module
      '\x1D' + '\x28' + '\x6B' + '\x03' + '\x00' + '\x31' + '\x45' + '\x30',             // <Function 169> select level of error correction (48,49,50,51) printer-dependent
      '\x1D' + '\x28' + '\x6B' + size1 + size0 + '\x31' + '\x50' + '\x30' + qr,          // <Function 080> send your data (testing 123) to the image storage area in the printer
      '\x1D' + '\x28' + '\x6B' + '\x03' + '\x00' + '\x31' + '\x51' +'\x30',              // <Function 081> print the symbol data in the symbol storage area
      '\x1D' + '\x28' + '\x6B' + '\x03' + '\x00' + '\x31' + '\x52' +'\x30',              // <Function 082> Transmit the size information of the symbol data in the symbol storage area
      // <!-- END QR DATA -->
   ];
  
   qz.print(config, data).catch(function(e) { console.error(e); });
