I want use this data and print via ajax in div element, but i cant understand, how i can do it. Maybe anybody know. Please, help me.

Do you have a serializer in your user entity? Because you are getting all users as entities. I suggest you to do something like this:

When you click a button or any element, call your route like this:

//change this element to your button
$('a.press-me').click(function() {
    $.ajax({
        url: 'YOUR ROUTE HERE',
        dataType: 'HTML',
        success: function (data) {
            $('#your-div').html(data);
        }
    });
});

//create a view users.html.twig or something like that...
{% if users is defined and users is not empty %}
    {% for user in users %}
        Name: {{ user.name }}
    {% endfor %}
{% else %}
    <p class="error">No data!</p>
{% endif %}

//add this line to top of your controller
use Symfony\Component\HttpFoundation\Request;

//add request variable to your action
public function printAction(Request $request)
{
    //you want to get users via ajax right? so check if the request is ajax or not
    if($request->isXmlHttpRequest()) {
        // Get all users
        $users = $this->getDoctrine()->getRepository('ModelBundle:Users')->findAll();

    //render a view and pass it as variable
    return $this->renderView('ModelBundle:Default:users.html.twig', ['users'] => $users);
    }
}
