If you mean print as on a "Printer" you need to look at the java.awt.print package. Printing in Java is somewhat complex... well actually printing is just complex anyway.

Here is a link to a good introduction article on the use of the print package:

good luck

dear ryan and palbano;

i appreciate for your help, thanks. and i actually got a sample code from sun, which can work, i dont know why. i compiled the program, gave no error, but when i run it give no result.

suppose, i want the program to print the text file on a Printer.

this is the simple printing.

import java.awt.*;
import java.io.*;
public class lpt
{

public static void main (String[] argv)
{
//check for argument
if (argv.length != 1)
{
System.out.println(&quot;usage: java lpt <printer name>&quot;
System.exit(0);
}

try
{

//open printer as if it were a file
FileOutputStream os = new FileOutputStream(argv[0]);
//wrap stream in &quot;friendly&quot; PrintStream
PrintStream ps = new PrintStream(os);

//print text here
ps.println(&quot;Hello world!&quot;

//form feed -- this is important
//Without the form feed, the text
//will simply sit in the print
//buffer until something else
//gets printed.
ps.print(&quot;\f&quot;

//flush buffer and close
ps.close();
}
catch (Exception e)
{
System.out.println(&quot;Exception occurred: &quot; + e);
}
}

}
