Digital BW, The Print

I would like to try to make some A3 negs for contact printing onto 
silver paper.  What is the best medium to do this on a 2100?  
Pictorico OHP?  Do I need an adjustment curve for printing the neg?  
If so, where can I find such a curve?  Last question (should really 
be first) I would like to hear of some experiences of people who 
have tried this hybrid.
Many many thanks in advance to all!
