How to Send JTable data to Print Job from Java Application?

In my Application, I have a JTable with data and I need to add a print button which adds the functionality of printing the data in a table on printer paper (send a printer job), how is that possible using the PrinterJob' class? I've been searching around for examples, but I couldn't find a simple example that prints some data from a JComponent.

This is one of the Websites I found: http://java.sun.com/products/java-media/2D/forDevelopers/sdk12print.html. But I am not sure what to focus on to understand how printing works (page format ...etc).

Thanks

hmmm,

todays Java6 Oracle tutotial about printing http://download.oracle.com/javase/tutorial/2d/printing/index.html contains http://download.oracle.com/javase/7/docs/api/javax/swing/JTable.html#print%28%29 which is described in JTable Tutorial including Runnable Examples, then you have to search (on this forum too) for correct Print paginations and orientations

for example 

PrintRequestAttributeSet set = new HashPrintRequestAttributeSet();
set.add(OrientationRequested.LANDSCAPE);
resultFxTable.print(JTable.PrintMode.FIT_WIDTH, header, footer, false, set, false);

note: I'm not sure that is possible correctly set Font, FontSize and FOntColor for PrintHeader and PrintFooter for JTable Printing

I solved the problem by painting the whole table to a printer page, resizing it accordingly etc. As printing is in fact painting just to a different receiver.

@Saher please check my answer to other question where I present links which were useful for me in understanding how the API works/can be applied.

EDIT:

Please do check the tutorials especially no. 2. The way I am doing it is that I have a MyPrintUtilityclass which implements Printable interface. Its constructor takes a component I want to print. When it takes the component it calculates how many pages it will take and stores page end points. Then I have a method I call for it that initailizes the print dialog.

    public void print()
    {
        PrinterJob printJob = PrinterJob.getPrinterJob();
        if(printJobName != null)
            printJob.setJobName(printJobName);
        printJob.setPrintable(this);    
        if(printJob.printDialog())
            try
            {
                //for faster printing, turn off double buffering
                disableDoubleBuffering(componentToPrint);
                System.out.println("Calling PrintJob.print()");
                printJob.print(new HashPrintRequestAttributeSet());
                System.out.println("End PrintJob.print()");
            }catch(PrinterException pe)
            {
                System.out.println("Error printing: " + pe);
            }finally//whatever happend (exception or not) turn back on the double buffering
            {
                enableDoubleBuffering(componentToPrint);
            }
    }

In the public int print(Graphics g, PageFormat pf, int pageIndex) method of the Printable interface I translate the graphic accordingly clipping the table for each page.

EDIT2:

You must seriously read this one. Here author explains how splitting on many pages works and how to translate the graphics and move the clip etc.
