The link has the form 
<http://www.example.at/administrator/index.php?page=order.order_printdetails&order_id=00000&no_menu=1&pop=1&tmpl=component&option=com_virtuemart>

and I want certain order_id's
I have access to the server directly, but I don't see any easy way to build
these sites directly.

In the end I'd like to have these pages as pdf-files.

Sorry for the confusing way to ask that question.
Any ideas?
Cheers again!
