Digital BW, The Print

I have zero experience with using duotone (or tritone etc) in PS but would like to try to get 
file versions of some of my images that match my prints' hue.  What would be the best way to 
start with this?  For example, how could I get a copy of the file to closely match Epson's Adv 
B&W "warm-darker" setting?

Cheers

Steve
