I was hoping Dan would handle this entire thread, but I'll butt in long
enough to say that in my experience there's nothing to be gained by
sending a bitmap file to an inkjet printer. You send your greyscale or
RGB file to the printer and the printer creates the stochastic output
automatically. All you need to do to prove to yourself that a bitmap
file isn't the best way to go is to try it once and see what happens. I
did it out of habit when I first switched from laser printer to inkjet
for my negatives; if my memory serves me right, it wasn't a pretty sight
and I've never done it again.
What's different about a bitmap that makes it work differently, is that
a bitmap file contains only one bit of information per pixel. It can't
"apply the proper number of colors" or do any other magic that can only
be accomplished with more information per pixel.
