Digital BW, The Print

I hope the moderator picks this up OK. I sent or thought I sent a 
quite detailed posting about which process to use for longevity and 
also mechanical ruggedness. I don't know if it went through.

I am looking for advice on the best process for the best mix of 
mechanical ruggedness and longevity, inkjet (I use an HP7960), Epson 
C86 with MIS EZTone inks, and dye-sub (particularly an Olympus P300, 
I hope that's the right model, the one I mean is about US$500-600).

The HP does nice B&W prints (at least for my taste); the Epson C86 
with the MIS EZTone inks should be archival and the Olympus puts 
down  a protective coating. I find the HP output can smear, the 
varnishing processes discussed in the Files section of this group are 
impractical in my living situation, and the Olympus uses dyes.

Any help is much appreciated.
