how to print data

Here's a quick-and-dirty example of how to get something to print from Java. As you can see, the Prinatable interface defines a print() method. That print() is passed in a Graphics objects. That Graphics object is then used by the object you want to print to print itself to. In this example, I just dummied up a Canvas whos paint(Graphics) method just writes out a string. This same call to paint() from print might work for a Table.

Of course this example is terribly rudimentary, but it does actually print (for me).

import java.awt.print.*;

import java.awt.*;

public class Main

{

public static void main(String[] args)

{

PrintableCanvas printMe = new Main().new PrintableCanvas();

printMe.setSize(500,500);

PrinterJob pj = PrinterJob.getPrinterJob();

pj.setPrintable(printMe);

try

{

pj.print();

}

catch(PrinterException pe)

{

pe.printStackTrace();

}

}

class PrintableCanvas extends Canvas implements Printable

{

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)

{

paint(graphics);

if(pageIndex == 0)

return PAGE_EXISTS;

else

return NO_SUCH_PAGE;

}

public void paint(Graphics graphics)

{

graphics.drawString("This was printed from Java",200,200);

}

}

}
