History is not printed on detail print.
Just use the history report to print history of an element.

Not very convenient way I would say...

Ticket #711 register to think about improvement.

You can chane default behaviour in /view/objectDetail.php.
replace :

  $displayHistory='NO';
  if (! $print and array_key_exists('displayHistory',$_SESSION)) {
    $displayHistory=$_SESSION['displayHistory'];
  }

with

  $displayHistory='NO';
  if (array_key_exists('displayHistory',$_SESSION)) {
    $displayHistory=$_SESSION['displayHistory'];
  }

Thanks - works this way
