    private javax.swing.JLabel jLabel1;
    private javax.swing.JTextField jTextField1;
    // End of variables declaration                   
}

```

and the main java class Test.java that execute the program 

```
    package test;

/**
 *
 * @author shaharnakash
 */
public class Test {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
         java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new NewJFrame().setVisible(true);
            }
        });
    }
}

```

the idea is to insert a value to the text field and after that click on the submit button it will execute the cmd command 

```
C:/PDF>pdfprint.exe -printer 'docPrint' -firstpage 1 -lastpage 1 -wtext 'value' -wo 100 -wa 50 -wf 'Arial' C:/readme.pdf

```

when i execute the program it will open the cmd and will not send the file to the printer

note: draft is the water mark change

i change to Process child = Runtime.getRuntime().exec("\"PDF\pdfprint.exe -printer docPrint -firstpage 1 -lastpage 1 -wtext "+value+" -wo 100 -wa 50 -wf Arial C:\readme.pdf");

and i still not working
