In addition to printing the data explorer view, I think it would be useful to print the Child Items view. For example, with a hierarchy like this:
Projects
1. First project
a. subproject 1
b. subproject 2
2. Second project
a. subproject 1
If I select "Projects" , the Child Items view shows all of the projects and their attributes (due dates, statuses, priorities, etc.). This is a useful, big picture overview of all the projects I'm working on. Then, if I select one of the projects such as Project 1, I can see each of its subprojects and their own attributes, as a snapshot of that project. These views would be useful to print, e.g. to bring to a meeting.
Just a thought.
