Printing Calendar Event Details

[Steff]

Hi there.

I made a site www.gewerbevereinalpnach.ch.
This Site is the problem: http://www.gewerbevereinalpnach.ch/index.php?mact=Calendar,cntnt01,default,0&cntnt01year=2008&cntnt01month=8&cntnt01event_id=8&cntnt01display=event&cntnt01lang=de_DE&cntnt01detailpage=&cntnt01return_id=21&cntnt01returnid=21

There are two print buttons. The one on the top right opens a new window with the calendar list view for print instead of the event details.
The one on de left side just opens a new window with the whole page and the calendar list view.

how can i print the event details, by clicking one of these buttons?

Thank you very mouch.

BTW:
Here you can find the template for event-details
