                        Toolkit   kit   =   Toolkit.getDefaultToolkit();   
                                                                      //获取工具箱
                                                          Properties   props   =   new   Properties();
                                                            
                                                            props.setProperty( "awt.print.printer ", "Epson5000 ");
                                                            props.setProperty( "awt.print.numCopies ", "1 ");
                                                            
                                                            if   (kit   !=   null)   {
                                                            //获取工具箱自带的打印对象
                                                            PrintJob   printJob   =   kit.getPrintJob(this,   "打印查询结果 ",   props);
                                                            if   (printJob   !=   null)   {
                                                            Graphics   pg   =   printJob.getGraphics();   //获取打印对象的图形环境
                                                          if   (pg   !=   null)   
                                                          {
                                                            try   
                                                          {
                                                                    jp1.printAll(pg);   
                                                                    this.repaint();
                    
                                                          }catch(Exception   e)
                                                          {
                                                          }
                                                            }
