Digital BW, The Print

I think it is just in the application of the curves where I'm seeing the
difference in smoothness.  For example, I took the usual 8-bit g/s test
file, converted it to 16 bit RGB, applied the sepia printing curve, then
converted back to 8-bit/channel RGB, and printed it through the Epson 1280
driver.  The final print was identical to the one that was left in 16 bit
for printing.  So, I suspect the issue is whether it's faster to have
Photoshop convert back to 8-bit or leave it there and let the driver do its
thing -- whatever that may be.  (I have not timed the processes.)
