Why does my short code get executed before other content?

I have the following text in a page. As you can see my shortcode is right at the bottom but somehow when the code runs, the out put of my shortcode is inserted at the top of the page instead of following its preceding content.

<img class="alignnone" title="title_enquires" src="http://localhost/barcelona/wp-content/uploads/2011/08/title_enquires.jpg" alt="" width="589" height="77" />
<img class="alignnone" title="contact_map" src="http://localhost/barcelona/wp-content/uploads/2011/08/contact_map.jpg" alt="" width="555" height="222" />

[barcelona_address]

here is my short code registration inside the function.php file:

<?php
add_shortcode( 'barcelona_address', 'barcelona_shortcode_handler' );

function barcelona_address_func()
{
    print "<p>sdsdsds</p>";
}

function barcelona_shortcode_handler( $atts, $content=null, $code="" ) 
{
   if (function_exists($code . "_func"))
   {
       call_user_func($code . "_func", $atts);
   }
}
?>

and the result is:

<p>sdsdsds</p>

<img class="alignnone" title="contact_map" src="http://localhost/barcelona/wp-content/uploads/2011/08/contact_map.jpg" alt="" width="555" height="222" />
