                for (int i = 0; i < 100; i++)
                {
                    string BagTagSvg;
                    BagTagSvg = File.ReadAllText(@"TestBagTag.svg");

                    Task.Factory.StartNew(() =>

                        mgTester.PrintBagTag(BagTagSvg);
                    });

                    Thread.Sleep(4000);
                }


                Console.WriteLine("Lot : " + j.ToString() );
                Console.ReadKey();
            }

            Console.WriteLine("Press any key to exit! ");
            Console.ReadKey();
            

        }
    }
