thanks at advance

import javax.swing.*;
import java.awt.print.*;
public class PrintUtilities implements Printable

private Component componentToBePrinted;
int iddoc;

int fontHeight,fontDescent;
double pageHeight,pageWidth,compWidth,compHeight;
double scale=1;
double compWidthOnPage,oneStringHeight;
int numRowsOnAPage;
double pageHeightForC;
int totalNumPages;

public static void printComponent(Component c,int iddoc)
{
new PrintUtilities(c,iddoc).print();
}
public PrintUtilities(Component componentToBePrinted,int iddoc)
{
this.componentToBePrinted=componentToBePrinted;
this.iddoc=iddoc;

}

public void print()
{
PrinterJob printJob=PrinterJob.getPrinterJob();
printJob.setPrintable(this);
if (printJob.printDialog())
{
try
{
printJob.print();
}
catch(PrinterException pe)
{
System.out.println("Error"+pe);
}
}
}

public int print(Graphics g,PageFormat pageFormat,int pageIndex)
{

if (iddoc==2)
{
pageFormat.setOrientation(PageFormat.LANDSCAPE);
}
pageHeight=pageFormat.getImageableHeight()-fontHeight;

{
return (NO_SUCH_PAGE);
}
else
{
g2.translate(pageFormat.getImageableX(),pageFormat.getImageableY());
