No AdminMenu in Wordpress Plugin

I am creating a plugin, I have a page in that plugin that displays a list of registrations.

On that page I want to make a button to print that list of registrations.

When that button is clicked a new page is opened with an window.print(); in the body tag. The page is printed.

However, on that page, Wordpress places the admin menu en footer, which are also printed.

I would like to print that page without the admin menu en footer. So my question is: How can I create a page in my own plugin that does not show the Wordpress menu's but is just plain text

While searching for brasofilo's solution to get working I found the use of the GET variable noheader.

That works great. Just add &noheader to your URL and you have no menus.

Based on Custom Admin Screen in iframe Thickbox. We can open an admin page inside a Thickbox and prevent WP from rendering its elements.

The trick is to intercept the submenu page with the hook load-$our_hidden_page_slug and exit its execution before it loads the rest of WP.

add_action('admin_menu', 'admin_menu_wpse_71437');
add_action( 'load-dashboard_page_my_hidden_page', 'intercept_thickbox_wpse_71437' ); 

/**
 * Add plugin page and a hidden and empty submenu page
 */
function admin_menu_wpse_71437() 
{
    add_menu_page(
        'TB', 
        '<span style="color:#e57300;">Thickbox</span>', 
        'edit_pages', 
        'open_hidden_page_in_thickbox', 
        'menu_page_wpse_71437',
        '', // no icon
        1 // create before Dashboard menu item
    );
    add_submenu_page(
        null, // doesn't shows up in the menu, attached to "index.php"
        'Hidden', 
        'Hidden', 
        'edit_pages', 
        'my_hidden_page', 
        'submenu_page_wpse_71437'
    );
}

/**
 * Main page
 */
function menu_page_wpse_71437() 
{
    wp_enqueue_style('thickbox');
    wp_enqueue_script('thickbox');
    ?>
    <h2>Print without menu and footer</h2>
    <a href="#" id="open-tb"><strong>Print table</strong></a>
    <?php print_table_so_24054478(); ?>
    <script type="text/javascript">
    jQuery(document).ready(function($) {   
        $("#open-tb").click(function() {                 
            tb_show("", "index.php?page=my_hidden_page&TB_iframe=true");
            return false;
        });
    });             
    </script>
    <?php
}

/**
 * Submenu page
 */
function submenu_page_wpse_71437() { /* Do nothing */ }

/**
 * Intercept our hidden/empty page and print the Thickbox content
 */
function intercept_thickbox_wpse_71437() 
{ 
    iframe_header(); 
    echo '<script>window.print();</script>';
    print_table_so_24054478();
    exit; // Exit to prevent the page continueing loading and adding the admin menu's etc. 
}

/**
 * Aux function to echo a table
 * from https://github.com/bueltge/WordPress-Admin-Style

function print_table_so_24054478()

    echo <<<HTML
