My Program Won't Print when its supposed to

Question

I've been trying to get a program that will automatically print txt files just by running it. Here's what I've come up with so far:
import java.io.*;
import javax.print.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;
import javax.print.event.*;
import java.awt.print.*;
import java.awt.*;
import java.awt.image.*;
import java.net.*;
import java.*;
import javax.*;
public class PrintTests8
public static void main(String[] args)
try
// Open the text file
InputStream is = new BufferedInputStream(new FileInputStream("test.txt"));
// Find the default service
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
// Create the print job
DocPrintJob job = service.createPrintJob();
Doc doc = new SimpleDoc(is, flavor, null);
// Print it
job.print(doc, null);
// It is now safe to close the input stream
is.close();
catch (PrintException e)
e.printStackTrace();
catch (IOException e)
e.printStackTrace();
}This will print out the file, but the problem is that it will only print it when another job, printed using in the normal, Ctrl+P type way, is printed. I hope that I can get help from you guys on this.

Answer 1

This error comes up:
sun.print.PrintJobFlavorException: invalid flavor
at sun.print.Win32PrintJob.print(Win32PrintJob.java:327)
at PrintTests8.main(PrintTests8.java:42)
And sorry for being impatient.
