Digital BW, The Print

I am fairly new at this and have a question about applying curves to 
adjust the image for ink type and paper. What are the advantages 
and/or disadvantages to applying a curve in an adjustment layer as 
the last step before printing vs applyig a curve through a transfer 
function. It seems like they accomplish the same thing. Am I missing 
something.

TIA

Eventually I hope to be able to look at the old photo I want to 
re-print and know which of the four VM curves I want to use (with the 
Sepia-Neutral inkset) on the paper being used. But so far, despite 
using only Epson Archival Matte (EAM) for starters, I'm having to 
print a "proof" for at least two of the four curves before I can make 
up my mind. That's quick and easy to do with the curving of the 
(ab?)normalized (right word?) RGB file coming at the end of the 
process. I'm so far innocent of any involvement with transfer 
functions, but if it would come earlier in the process, I guess 
proofing alternative functions wouldn't be so easy?
