          <table class="table table-bordered">
                   <tr>
                       <th></th>
                       <th>Printed</th>
                       <th>First Name</th>
                       <th>Last Name</th>
                       <th>Company</th>
                       <th>City</th>
                       <th>Country</th>
                     </tr>
                     <tr ng-repeat="item in items">
                        <td>
                           <input class="check-box" data-val="true" type="checkbox" ng-model="item.selected" ng-click="checkboxClick($event, item)">

You want a function that is launched with the ng-click event on the checkbox. This will also unselect all checkbox too. It iterates through all items, changing the state of each.

   <input type="checkbox" ng-model="selectAll" ng-click="checkAll()" />
   <tr ng-repeat="item in items">
        <td>
            {{item.name}}
        </td>
        <td>
             <input type="checkbox" ng-model="item.Selected" />
        </td>
    </tr>  

The controller could look something like this:

angular.module("myApp", [])
    .controller("checkboxCtrl", function($scope) {

    $scope.Items = [{
        name: "one"
    }, {
        name: "two"
    }, {
        name: "three"
    }];

    $scope.checkAll = function () {
        angular.forEach($scope.Items, function (item) {
            item.Selected = $scope.selectAll;
        });
    };   
});

you can do it with a simple variable in your HTML :

<input class="check-box" data-val="true" type="checkbox" ng-model="item.selected" ng-click="checkboxClick($event, item)" ng-selected="checkAll">
<button ng-click="toggleAllCheckboxes()">Check/Uncheck All</button>

and in your controller :

$scope.checkAll = false;
$scope.toggleAllCheckboxes = function(){
    $scope.checkAll = !$scope.checkAll;
}
