I have a LAN with 4 computers and a printserver. With the
Blaster problem running around, I turned on all the ICF
on my XP computers. After this I cannot see the
printserver from those computers. I heard that you need
to open up a few ports to solve this problem. Does anyone
know the exact port number that need to be opened to
communicate within the LAN?

To answer your specific question, many printservers use port 9100 TCP.
But you'd need to be more specific about the model.

On a more general point, the ICF is great for protecting the Internet
Connection.
You should not enable the ICF on your LAN connection, where it will kill f+p
sharing and most other things.

It should be enabled on your direct internet connection only.
