How to print PDF file in .NET Core

The Aspose.PDF library allows us to convert PDF files to XPS. This function can be useful for organizing the printing of documents. Let’s take a look at an example for using the default printer:

class Program
{
    static void Main()
    {
        // Create the secondary thread and pass the printing method for
        // the constructor's ThreadStart delegate parameter.
        Thread printingThread = new Thread(() => PrintPDF(@"C:\tmp\doc-pdf.pdf"));

        // Set the thread that will use PrintQueue.AddJob to single threading.
        printingThread.SetApartmentState(ApartmentState.STA);

        // Start the printing thread. The method passed to the Thread
        // constructor will execute.
        printingThread.Start();
    }//end Main

    private static void PrintPDF(string pdfFileName)
    {
        // Create print server and print queue.
        PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue();

        Aspose.Pdf.Document document = new Document(pdfFileName);
        var xpsFileName = pdfFileName.Replace(".pdf", ".xps");
        document.Save(xpsFileName,SaveFormat.Xps);

        try
        {
            // Print the Xps file while providing XPS validation and progress notifications.
            PrintSystemJobInfo xpsPrintJob = defaultPrintQueue.AddJob(xpsFileName, xpsFileName, false);
            Console.WriteLine(xpsPrintJob.JobIdentifier);
        }
        catch (PrintJobException e)
        {
            Console.WriteLine("\n\t{0} could not be added to the print queue.", pdfFileName);
            if (e.InnerException != null && e.InnerException.Message == "File contains corrupted data.")
            {
                Console.WriteLine("\tIt is not a valid XPS file. Use the isXPS Conformance Tool to debug it.");
            }
            Console.WriteLine("\tContinuing with next XPS file.\n");
        }
    }
}//end Program class

In this example, we convert PDF document into XPS and add it as a job to the queue of the local printer.
