I too find the same problem not locating all the print services, then i use defualt print service and it works, another error i was getting that of invalid flavor so i then get all the doc flavor supported by my printer and use AUTOSENSE. Following is the code that u can test:
import java.io.*;
import javax.print.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;
import javax.print.event.*;
public class PrintText1 {
     public static void main(String[] args) {
          System.out.println("Print Text");
          PrintText1 ps = new PrintText1();
     public PrintText1() {
          /* Construct the print request specification.
          * The print data is Postscript which will be
          * supplied as a stream. The media size
          * required is A4, and 2 copies are to be printed
          System.out.println(0);
          DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
          PrintRequestAttributeSet aset =
               new HashPrintRequestAttributeSet();
          aset.add(MediaSizeName.ISO_A4);
          aset.add(new Copies(1));
          aset.add(Sides.ONE_SIDED);
          //aset.add(Finishings.STAPLE);
          /* locate a print service that can handle it */
          System.out.println(1);
          PrintService defpservices = PrintServiceLookup.lookupDefaultPrintService();
          System.out.println("Default Printer " + defpservices.getName());
          /* create a print job for the chosen service */
          DocPrintJob pj = defpservices.createPrintJob();
          System.out.println(2);
          try {
               * Create a Doc object to hold the print data.
               * Since the data is postscript located in a disk file,
               * an input stream needs to be obtained
               * BasicDoc is a useful implementation that will if requested
               * close the stream when printing is completed.
               FileInputStream fis = new FileInputStream("file.txt");
                    Doc doc = new SimpleDoc(fis, flavor, null);
                    System.out.println(3);
                    /* print the doc as specified */
                    pj.print(doc, aset);
                    * Do not explicitly call System.exit() when print returns.
                    * Printing can be asynchronous so may be executing in a
                    * separate thread.
                    * If you want to explicitly exit the VM, use a print job
                    * listener to be notified when it is safe to do so.
          } catch (IOException ie) {
               System.err.println("IOException " + ie);
          } catch (PrintException e) {
               System.err.println("PrinterException " + e);
Try this code it will work for you to print the text file.
Now my problem is i am trying to print the html file and its printing the html file including all the html tags, can anybody help how can i be able to print only that area that viewable to user in the internet explorer and not all the html tags:
Following is my code which i had written using servlet:

          PrintWriter out = response.getWriter();
          /* Construct the print request specification.
          * The print data is HTMl which will be
          * supplied as a stream. The media size
          * required is A4, and 1 copies are to be printed
          System.out.println(0);
          //DocFlavor htmlFlavor = DocFlavor.URL.TEXT_HTML_US_ASCII;
          DocFlavor htmlFlavor = new DocFlavor("application/octet-stream", "java.net.URL");
          PrintRequestAttributeSet aset =
               new HashPrintRequestAttributeSet();

          /* locate a print service that can handle it */
          System.out.println(1);
          //PrintService[] pservices =

               //PrintService service = pservices[0];
          System.out.println("selected printer " + pservices.getName());
          DocFlavor[] sdf = pservices.getSupportedDocFlavors();
          System.out.println("Supported DocFlavors are: ");
          for( int r = 0; r < sdf.length; r++ )
               System.out.println(sdf[r].toString());
          /* create a print job for the chosen service */

          try

               out.println("<html><body>Printing Successful</body></html>");
          catch (PrintException e)
               System.err.println("PrinterException " + e);
Please help me out
