AngularJS Print Service


Example

Service:

angular.module('core').factory('print_service', ['$rootScope', '$compile', '$http', '$timeout','$q',
    function($rootScope, $compile, $http, $timeout,$q) {
        
        var printHtml = function (html) {
            var deferred = $q.defer();
            var hiddenFrame = $('<iframe style="display: none"></iframe>').appendTo('body')[0];
            
            hiddenFrame.contentWindow.printAndRemove = function() {
                hiddenFrame.contentWindow.print();
                $(hiddenFrame).remove();
                deferred.resolve();
            };

            var htmlContent =   "<!doctype html>"+
                                "<html>"+
                                    '<head><link rel="stylesheet" type="text/css" href="/style/css/print.css"/></head>'+
                                    '<body onload="printAndRemove();">' +
                                        html +
                                    '</body>'+
                                "</html>";

            var doc = hiddenFrame.contentWindow.document.open("text/html", "replace");
            doc.write(htmlContent);
            doc.close();
            return deferred.promise;
        };

        var openNewWindow = function (html) {
            var newWindow = window.open("debugPrint.html");
            newWindow.addEventListener('load', function(){ 
                $(newWindow.document.body).html(html);
            }, false);

        var print = function (templateUrl, data) {
            
            $rootScope.isBeingPrinted = true;

            $http.get(templateUrl).success(function(template){
                var printScope = $rootScope.$new()
                angular.extend(printScope, data);
                var element = $compile($('<div>' + template + '</div>'))(printScope);
                var waitForRenderAndPrint = function() {
                    if(printScope.$$phase || $http.pendingRequests.length) {
                        $timeout(waitForRenderAndPrint, 1000);
                    } else {
                        // Replace printHtml with openNewWindow for debugging
                        printHtml(element.html());
                        printScope.$destroy();

                };
                waitForRenderAndPrint();
            });
        };

        var printFromScope = function (templateUrl, scope, afterPrint) {
            $rootScope.isBeingPrinted = true;
            $http.get(templateUrl).then(function(response){
                var template = response.data;
                var printScope = scope;
                var element = $compile($('<div>' + template + '</div>'))(printScope);
                var waitForRenderAndPrint = function() {

                        $timeout(waitForRenderAndPrint);

                            $rootScope.isBeingPrinted = false;
                            if (afterPrint) {
                                afterPrint();
                            }
                        });
                    }
                };
                waitForRenderAndPrint();
            });
        };

        return {
            print : print,
            printFromScope : printFromScope
        }
    }
]);

Controller :

var template_url = '/views/print.client.view.html';
print_service.printFromScope(template_url,$scope,function(){
      // Print Completed
});
