Digital BW, The Print

Has anyone had a decent play with this?   I am particularly interested not in the Merge to HDR 
command but in the use of the compression back the other way.  In other words, you've done 
your multiple exposures, merged them into a 32 bit format but now need to print and so 
you're looking at the tools that compress the available range back to a printable bit depth...  
How's it work in practice?
