How print a ER diagram on new last version 9.2.009

I’m trying to finde the way to print a diagram but I can’t find anything about it.
At list export to PDF…

I would also like to know how to print these diagrams. At the moment, I can only view it on screen, which is no good for showing to a client for instance. Also, there are various inactive apps in my project which I would like to hide from the diagram, but there doesn’t seem to be any way to do that. To make the diagrams useful, we need to be able to decide which apps should appear and we need to be able to print, and also to export to some other format, eg PDF.
