I want to print an image with the following code, but .....

    import java.io.*;
    import javax.print.*;
    import javax.print.attribute.*;
    import javax.print.attribute.standard.*;
    import javax.print.event.*;
   
    public class BasicPrint {
        public static void main(String[] args) {
            try {
                // Open the image file
                InputStream is = new BufferedInputStream(
                    new FileInputStream("filename.gif"));
   
                // Find the default service
                DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF;
                PrintService service = PrintServiceLookup.lookupDefaultPrintService();
   
                // Create the print job
                DocPrintJob job = service.createPrintJob();
                Doc doc = new SimpleDoc(is, flavor, null);
   
                // Monitor print job events; for the implementation of PrintJobWatcher,
                // see e702 Determining When a Print Job Has Finished
                PrintJobWatcher pjDone = new PrintJobWatcher(job);
   
                // Print it
                job.print(doc, null);
   
                // Wait for the print job to be done
                pjDone.waitForDone();
   
                // It is now safe to close the input stream
                is.close();
            } catch (PrintException e) {
            } catch (IOException e) {
            }
        }
    }
