public class PrintFoo
{

public static void main(String args[])
{
PrintFoo ps = new PrintFoo();
}
public PrintFoo()
{
try
{
FileInputStream textStream;
textStream=new FileInputStream("tobeprinted.txt");

if(textStream==null)
{
System.out.println("asdfsaf");
return;
}

DocFlavor flavor=DocFlavor.INPUT_STREAM.POSTSCRIPT;
Doc mydoc=new SimpleDoc(textStream,flavor,null);
PrintRequestAttributeSet aset=new HashPrintRequestAttributeSet();
aset.add(new Copies(2));

PrintService[]services=PrintServiceLookup.lookupPrintServices(flavor,aset);
System.out.println(services.length);

if(services.length>0)
{
DocPrintJob job=services[0].createPrintJob();
try
{
job.print(mydoc,aset);
}
catch(PrintException pe)
{
System.err.println(pe);
}
}
}
catch(Exception ee)
{
System.err.println(ee);
}
}
}

import java.awt.print.*;

public void actionPerformed(ActionEvent e) {

// Get a PrinterJob
PrinterJob job = PrinterJob.getPrinterJob();
// Create a landscape page  format
PageFormat landscape = job.defaultPage();
landscape.setOrientation(PageFormat.LANDSCAPE);
// set  up a book
Book bk = new Book();
bk.append(new PaintCover(), job.defaultPage());
bk.append(new PaintContent(), landscape);
// Pass the book to the PrinterJob
job.setPageable(bk);
// Put up the dialog box
if (job.printDialog()) {
// print  the job if the user didn't cancel printing
try { job.print(); }
catch (Exception exc) { /* Handle Exception */ }
}
