<META NAME="ROBOTS" CONTENT="NOINDEX"> in the header of the page you don't want to be indexed. That is exactly what is done with the the page that is shown when you click on the 'printer friendlier' link at the bottom of each thread at WebmasterWorld.
takagi gave you the solution, however, you may want to make a relationship between your documents. Use the link tag in the head of your first document like this:
<link rel="alternate" type="text/html" media="aural" href="/your/path.html">
In that way, different user agents (and search engines) will know that both documents are different versions of the same information.
Hope it helps.
