Hi All,
Thanks all for all your kind advice.

After many test, I found that easiest is using the codes below can do
what I need to do :

        public void print() {
            PrintService ps =
PrintServiceLookup.lookupDefaultPrintService();
            try {
                String line;
                String s ="";

                int iCHR27Val = 27;
                char cCHR27 = (char)iCHR27Val;
                int iCHR4Val = 4;
                char cCHR4 = (char)iCHR4Val;
                s += cCHR27 + "c0" + cCHR4 ;
                s += "\n"+"\n"+"\n"+"\n"+"\n";
                s += " PRINTTING FROM JAPPLET PAGE : 1 v4" +
"\n";
                s += " This is FIRST LINE " + "\n";
                s += " This is SECOND LINE " + "\n";
                s += " This is THIRD LINE " + "\n";
                s += " This is ** LAST ** LINE " + "\f";

                // now print!!
                if (1 > 0) {
                    // PrintService ps =
PrintServiceLookup.lookupDefaultPrintService();
                    if (ps!=null) {
                        //JOptionPane.showMessageDialog(null,"selected
printer " +ps.getName());
                        //System.out.println("selected printer " +
ps.getName());

                        PrintRequestAttributeSet aset= new
HashPrintRequestAttributeSet();
                        DocFlavor flavor =
DocFlavor.INPUT_STREAM.AUTOSENSE;
                        //DocFlavor flavor =
DocFlavor.SERVICE_FORMATTED.PRINTABLE;
                        aset.add(new MediaPrintableArea
(100,400,210,160,Size2DSyntax.MM));
                        DocPrintJob pj = ps.createPrintJob();
                        try {

                            ByteArrayInputStream b =new
ByteArrayInputStream(s.getBytes());

                            Doc doc = new SimpleDoc(b, flavor, null);
                            pj.print(doc, aset);

                            JOptionPane.showMessageDialog(null,"end
printing");
                        } catch (PrintException e) {
                            JOptionPane.showMessageDialog
(null,e.getMessage());

                        } catch(Exception e1) {
                            JOptionPane.showMessageDialog
(null,e1.getMessage());
                        }

                    } else {

                        JOptionPane.showMessageDialog(null,"no
Printer");
                    }
                }

            } catch (Exception e) {
            } finally {
                if (br != null)
                    try { br.close(); } catch (IOException ignore) {}
                if (in != null)
                    try { in.close(); } catch (IOException ignore) {}
            }

        }

Thank you, if you have further advise, pls welcome..
