Hide menu items for visitors and filter based on role

Question

In my menu i've got some menu items that i don't want to show to people who aren't logged in. One of these i only want to show to logged in users of a certain roles the other to everyone logged in.

So one of them is called 'My Printer'. This should be visible to everyone that is logged in.

The other is called 'Partners'. This should only be visible to users with the partner role.

I've tried using Role Scoper but i find it very difficult to use and it doesn't make a lot of sense. It also interferes with a lot of other things as well which i don't need.

Is there anyway i can hide menu items based on their role?

Thanks

EDIT

I've created the menu using the admin and placed that menu in a theme location. The menu items i want to hide are in this menu.

Thanks for the 2 answers below, but neither achieve what i'm after.

You have to override the Walker_Nav_Menu class!

add_filter( 'wp_get_nav_menu_items', 'hide_menu_items_from_non_partners' );

function hide_menu_items_from_non_partners($items) {
    if ( current_user_can( 'partner' ) ) {
        return $items;
    }
    $ids_of_pages_to_hide = array(2,3,4); // you need to put here ids of pages you wish to hide
    foreach ( $items as $key => $item ) {
        if ( in_array($item->object_id, $ids_of_pages_to_hide ) ) unset( $items[$key] );
    }
    return $items;
}

You need to define something like this in your header.php file.

<?php
if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    echo 'Welcome, visitor!';
}
?>

Create a new role with the following code and put it in your functions.php

add_role('partners', 'Partners', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));

Now lets say your partners has the capability "edit_published_posts". You can define the menu like this.

<?php
    if ( is_user_logged_in() ) {
            if(current_user_can('edit_published_posts')) {
            echo 'Welcome, Partner!';
            }
            else {
            echo 'Welcome, registered user!';
            }
    } 
    else {
        echo 'Welcome, visitor!';
    }
    ?>

You could do this by creating different menus in Appearance -> Menus, and then use something like this to show the menu for the current role:

     <?php
        global $wp_roles;

        foreach ( $wp_roles->role_names as $role => $name ) :
            if (current_user_can( $role ) && $role == 'partner') {
                wp_nav_menu( array( 'theme_location' => 'partner-menu' ) );
            }
        endforeach;
    ?>
