What I understand you need to have different names on the windows. So test this:

window.open("http://www.google.se", "google");
window.open("http://msdn.microsoft.com/sv-se/", "msdn");

Or in your case:

window.open('PrintLettreVoit.aspx?Id=3','ID3');
window.open('PrintLettreVoit.aspx?Id=7','ID7');
