Bouton imprimer pas disponible dans ReportViewer à l'aide de IE11

J'ai utilisé le code de la page(http://msdn.microsoft.com/en-us/library/ms252091.aspx) et créé une classe pour ça. Vous pouvez ajouter un bouton à la page et de l'appeler.

---- Call ---------
ReportPrinter prnt = new ReportPrinter();
prnt.Print(rpt.LocalReport);
