This is my ContactController.php

 <?php

namespace Savvy\ContactBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;



class ContactController extends Controller
{
    /**
     * @Route("/contact", name="savvy_contact")
     * @Template()
     */
    public function indexAction()
    {

         $form = $this->createForm(new ContactType());

         return array(
             'form' => $form->createView()


         );
    }
    /**
     * @Route("/contact/submit", name="savvy_submit_contact")
     * @Method("POST")
     * @Template("SavvyContactBundle:Contact:index.html.twig")
     */
     public function submitAction()
    {
        //Create a new contact entity instance
        $contact = new Contact();
        $form = $this->createForm(new ContactType(), $contact);
        //Bind the posted data to the form
        $form->bind($this->getRequest());
        //Make sure the form is valid before we persist the contact
        if($form->isValid()){
            //Get the entity manager and persist the contact
            $em = $this->getDoctrine()->getManager();
            $em->persist($contact);
            $em->flush();
            //Redirect the user and add a thank you flash message


            return $this->redirect($this->generateUrl("savvy_contact"));
        }

        return array(
            'form' => $form->createView()
        );
    }
     /**
     * @Route("/show", name="savvy_show")

     * @Template("SavvyContactBundle:Contact:show.html.twig")
     */
    public function showAction() {

         $em = $this->getDoctrine()->getManager();


        //
        //$entities = $em->getRepository('QsystemsUserBundle:Printer')->findAll();

         $dbl = 'SELECT c FROM SavvyContactBundle:Contact c';

  $query = $em->createQuery($dbl);

    $paginator  = $this->get('knp_paginator');
    $pagination = $paginator->paginate(
        $query,
        $this->get('request')->query->get('page', 1)/*page number*/,
        10/*limit per page*/
    );

        return $this->render('SavvyContactBundle:Contact:show.html.twig', array(
            'pagination' => $pagination,
        ));
    }
}

This is my twig file

{% block content %}

{# total items count #}
<div class="count">
    {{ pagination.getTotalItemCount }}
</div>
<table>
<tr>
{# sorting of properties based on query components #}
    <th>{{ knp_pagination_sortable(pagination, 'Id', 'a.id') }}</th>
    <th{% if pagination.isSorted('a.Title') %} class="sorted"{% endif %}>{{ knp_pagination_sortable(pagination, 'Title', 'a.title') }}</th>
</tr>

{# table body #}
{% for entity in pagination %}
<tr {% if loop.index is odd %}class="color"{% endif %}>
    <td>{{ entity.id }}</td>
    <td>{{ entity.title}}</td>
</tr>
{% endfor %}
</table>
{# display navigation #}
<div class="navigation">

</div>

    {% endblock content %}

Are you sure your Knp Paginator bundle is successfully installed ?

composer.json:

"knplabs/knp-paginator-bundle": "~2.4"

do:

php composer.phar update knp-paginator-bundle

app/AppKerner.php:

new Knp\Bundle\PaginatorBundle\KnpPaginatorBundle(),

then check with:

php app/console cache:clear
