Hello Marty,
PowerPoint only prints the slide contents without the
animation builds. In other words, all objects are flattened,
since obviously, print is a flat medium.
How do you want it to look in print?
Do you want to print the animation builds successively?
Do you want it printed object by object, or second by second?
As you can see, there are a lot of variables that would go
into printing an animation - PowerPoint doesn't bother trying
to second-guess what could amount to a very complex set of
user expectations, and so renders the final slide as
it looks with everything on there in the non-animated
state.
If printing the animations is really important for you,
you might consider creating the animations on separate slides,
in which case the animation builds will print.
For instance, let's say you want shape A to fade in,
shape B to fade in after that, shape C to fade in,
and then shape C to fade out.
If you create four slides, one for each succession of the
animation build, and set the slide transitions between them
to automatic, they will then print separately, and
you can show people the sequence of the animation.
Hope this helps you out a little bit.
Jeff
