如何使用角截图打印整个dom元素?

我已经尝试在网页上复制/粘贴示例代码: https://weihanchen.github.io/angular-screenshot/ 问题是他们使用了一个完整的控制器,我的控制器被视图分隔开。我就是这样把它们添加到我的“main”js中的:

    .state("main.pallet", {
        url: "/palletize",
        templateUrl: "app/views/pallet.html",
        data: {pageTitle: 'Entarimado.'},
        controller: "Pallet",
        resolve: {
            deps: ['$ocLazyLoad', function($ocLazyLoad) {
                return $ocLazyLoad.load({
                    name: 'TepaPrime',
                    insertBefore: '#ng_load_plugins_before', // load the above css files before '#ng_load_plugins_before'
                    files: [
                        'app/js/filters/filters.js',
                        'app/js/directives/numericFormat.js',
                        'app/js/directives/trimText.js',
                        'app/js/directives/nextOnEnter.js',
                        'app/js/factories/crud.factory.js',
                        'app/js/controllers/modals/palletContent.js',
                        'app/js/controllers/pallet.js',
                        'app/js/services/printDocument.js'
                    ]                    
                });
            }]
        }
    })

这是我的printdocument.js,我在这里粘贴了示例中的代码(并对其进行了修改以使其正常工作):

'use strict';
function appController($scope) {
  var self = this;
  self.fullScreenApi;
  self.downloadFull = downloadFull;
  this.downloadFull = function() {
      if (self.fullScreenApi) self.fullScreenApi.downloadFull();
   }
   return downloadFull;
}
angular
    .module('TepaPrime')
    .service('printDocument', appController);

然后通过执行以下操作将其注入视图的控制器:

function Pallet($rootScope, $scope, $state, $timeout, $uibModal, $http, $filter, crud, sessionService, printDocument) {
  ...
}

问题是它不起作用,导致整个页面崩溃并抛出此错误:

错误:[$injector:unpr] http://errors.angularjs.org/1.5.0/ $注射器/UNPR?P0=copeprovider%20%3c-%20%24范围%20%3c-%20printdocument

我真的很感激你的帮助,因为我已经被困在这里很长时间了,似乎无法找到解决办法。
