    String name = "Test print job";
    Properties properties = new Properties();
    PrintJob pj = Toolkit.getDefaultToolkit().getPrintJob(new MainClass(), name, properties);
    if (pj != null) {
        printDimensions(pj.getGraphics(), pj.getPageDimension());
        pj.end();/*from   w w w  .j  av  a 2 s  . co m*/
    }
}

    add("Center", canvas);
    setSize(500, 500);/*from  w w w  .j a va  2s .c  om*/
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setVisible(true);
    String name = "Test print job";
    Properties properties = new Properties();
    PrintJob pj = Toolkit.getDefaultToolkit().getPrintJob(PrintSampleApp.this, name, properties);
    if (pj != null) {
        canvas.printAll(pj.getGraphics());
        pj.end();
    }
}

From source file:JuliaSet2.java

public void print() {
    // Create some attributes objects. This is Java 1.3 stuff.
    // In Java 1.1, we'd use a java.util.Preferences object instead.
    JobAttributes jattrs = new JobAttributes();
    PageAttributes pattrs = new PageAttributes();

    // Set some example attributes: monochrome, landscape mode
    pattrs.setColor(PageAttributes.ColorType.MONOCHROME);

    // Print to file by default
    jattrs.setDestination(JobAttributes.DestinationType.FILE);

    // Look up the Frame that holds this component
    Component frame = this;
    while (!(frame instanceof Frame))

    // Get a PrintJob object to print the Julia set with.
    // The getPrintJob() method displays a print dialog and allows the user
    // to override and modify the default JobAttributes and PageAttributes
    Toolkit toolkit = this.getToolkit();
    PrintJob job = toolkit.getPrintJob((Frame) frame, "JuliaSet1", jattrs, pattrs);

    // We get a null PrintJob if the user clicked cancel
    if (job == null)
        return;

    // Get a Graphics object from the PrintJob.
    // We print simply by drawing to this Graphics object.
    Graphics g = job.getGraphics();

    // Center the image on the page
    Dimension pagesize = job.getPageDimension(); // how big is page?
    Dimension panesize = this.getSize(); // how big is image?
    g.translate((pagesize.width - panesize.width) / 2, // center it
            (pagesize.height - panesize.height) / 2);

    // Draw a box around the Julia Set and label it
    g.drawRect(-1, -1, panesize.width + 2, panesize.height + 2);
    g.drawString("Julia Set for c={" + cx + "," + cy + "}", 0, -15);

    // Set a clipping region
    g.setClip(0, 0, panesize.width, panesize.height);

    // Now print the component by calling its paint method
    this.paint(g);

    // Finally tell the printer we're done with the page.
    // No output will be generated if we don't call dispose() here.
    g.dispose();
