I want to print invoices which are based on a template.
How can I add a template n-times to a Word-Document and replace the values for each page?

You want to print N different invoices using the same template, right?

Yes. But I want to get one big file with N pages in it.

Actually, there is no such functionality. It returns one document per each template. Template Processor doesn't merge files.
