Fix:
invoke $window.print inside $timeout()

AngularPrint.directive('printBtn',['$window','$timeout', function($window,$timeout){
       return {
           restrict: 'A',
           link: function(scope, element){
               element.on('click', function(event){
                 
                   $timeout(function () {
                         $window.print();
   }, 0); 
               });
           }
       };
   }]);
