Imtiyaz,

Here is a sample for that:

    <style>
      html,
      body,
      #viewDiv {

        var webmap = new WebMap({
          portalItem: {
            // autocasts as new PortalItem()
            id: "d6d830a7184f4971b8a2f42cd774d9a7"

        });

        var view = new MapView({
          container: "viewDiv",
          map: webmap
        });

        view.when(function() {
          var print = new Print({
            view: view,
            // specify your own print service

          // Add widget to the top right corner of the view
          view.ui.add(print, "top-right");
          
          print.viewModel.watch('state', function(state){
            if(state === 'ready'){
              setTimeout(() => {
                var button = document.createElement('button');
                button.setAttribute('ID', 'btnClearPrints');
                button.innerText = 'Clear Prints...';
                button.className = 'esri-button';
                button.addEventListener('click', clearPrints);
                var pc = document.getElementsByClassName('esri-print__container')[0]
                pc.appendChild(button);
              }, 500);
            }
          });

          function clearPrints(){

            while (prints.length > 0) prints[0].remove();

        });
      });
    </script>
