Digital BW, The Print

Regarding not printing from PhotoShop:

Could this be an issue with the total number of pixels? I seem to 
recall that there was a limit on some versions of PS that would not 
allow you to print correctly. 30,000 seems to come to mind, but I might 
be wrong.

Also a cheaper paper suggestion: Hahnemuhle ArtProof. Still not 
extremely cheap, but if you are working with the other papers in that 
family, a good color match and it seems to hold just as much ink as the 
other coated papers.

As far as the rest goes... sorry, can't help.
