java printing code not working

Question

I am using the java code shown below to print a text file on an HP DeskJet1000 USB printer attached to my computer. Whenever I run this code a printing job is sent but the printer does not print anything. The status shows that the printer is printing but it doesn't even intake a page. Please help! My code follows:

package printing;

import java.io.FileInputStream;
import javax.print.*;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;

/** @author Majid */
public class Printing {
    public static void main (String [] args) {
        // TODO code application logic here
        DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet ();
        /* locate a print service that can handle it */
        PrintService [] pservices = PrintServiceLookup.lookupPrintServices (flavor, aset);
        /* create a print job for the chosen service */
        int printnbr = 0;
        DocPrintJob pj = pservices [printnbr].createPrintJob ();
        try {
            FileInputStream fis = new FileInputStream ("e:/fypdatabase/test.txt");
            Doc doc = new SimpleDoc (fis, flavor, null);
            //PrintJobWatcher pjDone = new PrintJobWatcher (pj);
            /* print the doc as specified */
            pj.print (doc, aset);
        }
        catch (Exception ex) {
            ex.printStackTrace ();
        }  
    }
}

@ moskiteau why you hard code number [2] in

DocPrintJob pj = pservices[2].createPrintJob();

instead of getting the value of printer as pservices' index?

DocPrintJob pj = pservices[printer].createPrintJob();

(im sorry if this isnt the right place to clarify this question, but this is my very first question here and didnt find how to ask this in any other way)
