Impression de fichiers pdf à l'aide de java

Je veux imprimer un document en utilisant java cependant, le programme réussit mais mon imprimante n'imprime rien. Pourquoi est-il comme ça? Avez-vous des solutions pour cela? Si mon imprimante n'est pas prise en charge au format pdf, existe-t-il un moyen d'imprimer le fichier pdf ou même les fichiers docx?

package useprintingserviceinjava;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.event.PrintJobAdapter;
import javax.print.event.PrintJobEvent;
public class UsePrintingServiceInJava {

    private static boolean jobRunning = true;

    public static void main(String[] args) throws Exception {


  InputStream is;
   is = new BufferedInputStream(new FileInputStream("PAPER_SENSOR.pdf"));

  DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF;

  PrintService service = PrintServiceLookup.lookupDefaultPrintService();

  DocPrintJob printJob = service.createPrintJob();

  printJob.addPrintJobListener(new JobCompleteMonitor());

  Doc doc = new SimpleDoc(is, DocFlavor.INPUT_STREAM.AUTOSENSE, null);

  printJob.print(doc, null);

  while (jobRunning) {
        Thread.sleep(1000);
  }

  System.out.println("Exiting app");

  is.close();

    }

    private static class JobCompleteMonitor extends PrintJobAdapter {
        @Override
        public void printJobCompleted(PrintJobEvent jobEvent) {
            System.out.println("Job completed");
            jobRunning = false;
        }
    }

}

C'est le code que j'ai recherché mais il n'imprime toujours pas. Voici un autre code basé sur mes recherches:

package javaapplication24;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.event.PrintJobEvent;
import javax.print.event.PrintJobListener;
public class HandlePrintJobEvents {

public static void main(String[] args) throws Exception {

        // create a PDF doc flavor
        try ( // Open the image file
                InputStream is = new BufferedInputStream(new FileInputStream("C:\\Users\\JUSTINE\\Documents\\thesis document\\PAPER_SENSOR.pdf"))) {
            // create a PDF doc flavor

            DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF;

            // Locate the default print service for this environment.

            PrintService service = PrintServiceLookup.lookupDefaultPrintService();

            // Create and return a PrintJob capable of handling data from

            // any of the supported document flavors.

            DocPrintJob printJob = service.createPrintJob();

            // register a listener to get notified when the job is complete

            printJob.addPrintJobListener(new PrintJobMonitor());

            // Construct a SimpleDoc with the specified

            // print data, doc flavor and doc attribute set.

            Doc doc = new SimpleDoc(is, DocFlavor.INPUT_STREAM.AUTOSENSE, null);

            // Print a document with the specified job attributes.

            printJob.print(doc, null);
        }

}

private static class PrintJobMonitor implements PrintJobListener {

    @Override
    public void printDataTransferCompleted(PrintJobEvent pje) {
        // Called to notify the client that data has been successfully
        // transferred to the print service, and the client may free
        // local resources allocated for that data.
    }

    @Override
    public void printJobCanceled(PrintJobEvent pje) {
        // Called to notify the client that the job was canceled
        // by a user or a program.
    }

    @Override
    public void printJobCompleted(PrintJobEvent pje) {
        // Called to notify the client that the job completed successfully.
    }

    @Override
    public void printJobFailed(PrintJobEvent pje) {
        // Called to notify the client that the job failed to complete
        // successfully and will have to be resubmitted.
    }

    @Override
    public void printJobNoMoreEvents(PrintJobEvent pje) {
        // Called to notify the client that no more events will be delivered.
    }

    @Override
    public void printJobRequiresAttention(PrintJobEvent pje) {
        // Called to notify the client that an error has occurred that the
        // user might be able to fix.
    }

}

}

Merci:) * J'ai déjà essayé 2 imprimantes mais je ne peux toujours pas imprimer.
