Cannot print on another paper tray via IPP

i'm trying to print a document on the second paper tray with IPP (Internet Printing Protocol). I'm using this npm IPP-Library.

But at any time i try to print a document my printer shows a message that i need to add paper to the first paper tray and the console output of says Printed: successful-ok.

var ipp = require("ipp");
var PDFDocument = require("pdfkit");
var concat = require("concat-stream");

var doc = new PDFDocument;
doc.text("Hello World");

doc.pipe(concat(function (data) {
    var printer = ipp.Printer("MY_URL");

    var file = {
        "operation-attributes-tag": {
            "requesting-user-name": "admin",
            'attributes-charset': 'utf-8',
            'attributes-natural-language': 'de'
        },
        "printer-attributes": {
            "media-col": {
                "media-source": "tray-2"
            },
        },
        data: data
    };
    printer.execute("Print-Job", file, function (err, res) {
        console.log("Printed: " + res.statusCode);
    });
}));

doc.end();

The other variant i tried is following:

var PDFDocument = require("pdfkit");
let fs = require('fs')
var ipp = require('ipp');
var uri = "http://10.1.205.71";


var msg = new Buffer(
  '0200'+ //Version
  '000201e6d5f2'+
  '01'+ //Operation attributes tag (your information in the Operation attributes might be different)
    '47'+ //charset tag
    '0012'+ //length
    '617474726962757465732d63686172736574'+ //attributes-charset
    '0005'+ //length
    '7574662d38'+ //utf-8

    '34'+ //begin collection
      '0009'+ //length
      '6d656469612d636f6c'+ //media-col
      '0000'+ //value length
      '4a'+ //collection entry
      '0000'+ //name length
      '000c'+ //value length
      '6d656469612d736f75726365'+ //media-source
      '44'+ // collection entry
      '0000'+ //name length
      '0006'+ //value length
      '747261792d32'+ //tray-2
    '37'+ //end of collection
    '00000000'+ //name length and value length
  '03', 'hex');

var doc = new PDFDocument;
doc.text("Hello World");

var buffers = [];
doc.on('data', buffers.push.bind(buffers));
doc.on('end', function(){
  var buf = Buffer.concat(buffers);
  var catBuf = Buffer.concat([msg, buf]);
  ipp.request(uri, catBuf, function(err, res){
    if(err){
      return console.log(err);
    }
    console.log(JSON.stringify(res,null,2));
  });
});
doc.end();

But then i got this error message:

My printer does not support IPP, but i shared it on my Macbook, which provides an IPP service for all shared printers. If i'm using the first paper tray and have paper in there everything is fine, but for my project it is necessary to print on other trays, too.

Does anyone have an idea how to print successfully on another paper tray?
