PrintQueue.AddJob method doesn't work

I am working on an application where I have to put an extra line of text after original printed text.

For this, I am using FindFirstPrinterChangeNotification and FindNextPrinterChangeNotification methods of Print Spooler API which works fine.

I am able to get Print Queue which shows number of job count 1.

I am using following code to add a new job in Print Queue:

        // Create the printer server and print queue objects
        LocalPrintServer localPrintServer = new LocalPrintServer();
        PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue();

        // Call AddJob
        PrintSystemJobInfo myPrintJob = defaultPrintQueue.AddJob();

        // Write a Byte buffer to the JobStream and close the stream
        Stream myStream = myPrintJob.JobStream;
        Byte[] myByteBuffer = UnicodeEncoding.Unicode.GetBytes("This is a test string for the print job stream.");
        myStream.Write(myByteBuffer, 0, myByteBuffer.Length);
        myStream.Close();

My code execute successfully without any exception but the new job doesn't get printed along with original text.

As Tony pointed out in the comments, the JobStream has changed in .NET Framework 4.5 for Windows 8 and up to use the XPS document format. If you want to print, you're going to have to follow the guideline.

I have not found a solution that works, but you can try using the XPS Printing API

The closest solution to that I found were here and here as mentioned by Microsoft here
