At this time, the PDF diagrams are only available to those who have an internet connection.  The reason is simple: the most current edition of any diagram set is always available 24/7/365 from the server.  A bound format becomes outdated when an update has been published.  Therefore, because of the purpose and scope of the project, there are no plans to place these diagrams into a bound format.  Of course, you may print the diagrams and compile them into a bound format.
