Important Printing my family tree

I want to print my family tree for our family reunion. Why isn't there an option to print the descendancy chart? If there is one, why isn't it easy to find and use?

Because we must save trees.

There are enough possibilities for output in different file-formats from jpg over svg to pdf

This is what I think produces the best results:
1. Use the module Descendants chart by Rico Sonntag
2. Select orientation down and number of generations
3. Export as SVG
4. Open the SVG file in your browser
5. Select paper size and print without headers and now you have a full page chart
