I've tested your program....

Win XP SP3
Im using jdk 6 update 3
bin path already set

Build and Runtime error. why? using Runtime? or JavaCompiler class?

I suggest you shall create a documentation about your program. How should specifically use it, its condition before using it, and EULA ( detailed )...

Not bad, keep it up.....

Here is a simple PrintData Class, it will print a page.

Code:

public class PrintData implements Printable{
    private Component data;
    
    public PrintData(Component e){
        this.data = e;
    }
    
    public void setValue(){
        new PrintData(data).initializePrint();
    }
    
    public void initializePrint(){
        PrinterJob proceed = PrinterJob.getPrinterJob();
        proceed.setPrintable(this);
        if(proceed.printDialog()){
            try{
                proceed.print();
            }catch(Exception e){
                JOptionPane.showMessageDialog(null,"AN ERROR OCCURED WHILE INITIALIZING PRINTER");
            }
        }
    }
    
    public int print(Graphics g, PageFormat format, int page){
        int value = Printable.PAGE_EXISTS;
        Font pattern = new Font("Arial",Font.PLAIN,10);
        if(page>0){value = Printable.NO_SUCH_PAGE;}
        Graphics2D g2D = (Graphics2D)g;
        g2D.setFont(pattern);
        g2D.translate(format.getImageableX(),format.getImageableY());
        data.setFont(pattern);
        data.paint(g2D);
        return value;
    }
}

where Component e should be the source of text ( TextArea for example )
