I'm trying to print a document using javax.print.*

I get no error message with the following code but nothing is sent to the Printer Setup Utility or whatever. No printout...

This has to both work on OSX and Windows.

If you have time to have a look... I'd love to know what I'm missing out.

        post("- printer 0.01: Olivier Pasquet _2007");

public void setfile(String args[]) throws Exception {

        fin = new FileInputStream(filename);

            post("? error : printer no file to print");

        } catch(FileNotFoundException ffne) {

            post("? error : printer file not found");

        InputStream is = new BufferedInputStream(new FileInputStream(filename));

        // Find the default service

        DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF;

        PrintService service = PrintServiceLookup.lookupDefaultPrintService();

        DocPrintJob job = service.createPrintJob();

        Doc doc = new SimpleDoc(is, flavor, null);

        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

    // Monitor print job events; for the implementation of PrintJobWatcher,

    // see e702 Determining When a Print Job Has Finished

    PrintJobWatcher pjDone = new PrintJobWatcher(job);

    // Wait for the print job to be done

    // It is now safe to close the input stream

        } catch (PrintException e) {

        } catch (IOException e) {

    outlet(0, PrintServiceLookup.lookupDefaultPrintService().toString());

// true if it is safe to close the print job's input stream

job.addPrintJobListener(new PrintJobAdapter() {

public void printJobCanceled(PrintJobEvent pje) {

public void printJobCompleted(PrintJobEvent pje) {

public void printJobFailed(PrintJobEvent pje) {

public void printJobNoMoreEvents(PrintJobEvent pje) {

I get no error message with the following code but nothing is sent to the Printer Setup Utility or whatever. No printout...
Nothing on the console too.

You seem to be silently swallowing potential exceptions:

are you sure neither PrintException nor IOException are being thrown?

            post("Got Printer Exception pe:" +e.getMessage());

            post("Cause of pe is " + e.getCause());

			post("Got Printer Exception pe:" +e.getMessage());

Well, if not that, then have you checked which PrintJobListener method 

is being invoked when it finishes? All your implementations do the same 

thing, it may be worth checking the PrintJobEvent to see whether it 

>< yea. I'm sure. I get no message from there...

Well, if not that, then have you checked which PrintJobListener method 
is being invoked when it finishes? All your implementations do the same 
thing, it may be worth checking the PrintJobEvent to see whether it 
contains any clues.

had the same problem. I just stopped using a separate object to wait until the print was done and implemented the PrintJobListener in the applet subclass.. like

public void printDataTransferCompleted(PrintJobEvent pje)

JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);

public void printJobCanceled(PrintJobEvent pje)

public void printJobCompleted(PrintJobEvent pje)

public void printJobFailed(PrintJobEvent pje)

public void printJobNoMoreEvents(PrintJobEvent pje)

public void printJobRequiresAttention(PrintJobEvent pje)

protected InputStream is;
     public void printDataTransferCompleted(PrintJobEvent pje)
      {
        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
      public void printJobCanceled(PrintJobEvent pje)
      {
            testPrinting.setEnabled(true);
        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
      public void printJobCompleted(PrintJobEvent pje)
      {
        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
      public void printJobFailed(PrintJobEvent pje)
      {
        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
      public void printJobNoMoreEvents(PrintJobEvent pje)
      {

        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
      public void printJobRequiresAttention(PrintJobEvent pje)
      {

        try
        {
         is.close();
        }
        catch(Exception exp)
        {
         JOptionPane.showMessageDialog(null, exp.toString(), "ERROR", JOptionPane.ERROR_MESSAGE);
        }
      }
