$(document).on("submit", "form", function(event){
        window.onbeforeunload = null;
});

You can use onsubmit event and remove onbeforeupload listener in it, so, modified script:

<script>
    window.onbeforeunload = function(e) {
      return 'You application form is not submitted yet.';
    };
    document.getElementById("your_form_id_here").onsubmit = function(e) {
      window.onbeforeunload = null;
      return true;
    };
    WinPrint.document.write('<span style="font-size:22px">' + prtContent.innerHTML + '<span>');
</script>
