Printing pdf files using java
<p>I want to print a document using java however, the program is successful but my printer is not printing anything. Why is it like that? Do you any solutions for this? If my printer is not pdf supported, is there any way to print the pdf file or even docx files?</p>

<pre><code>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;

    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;
        }
    }

<p>This is the code I researched but still it does not print. Below is another code based on my research:</p>

<pre><code>package javaapplication24;

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.
    }
