Digital BW, The Print

Hi All,

I'm new to digital printing and am researching options before buying
my first printer.

I think I would be interested in trying black-only printing along the
lines of what Clayton Jones describes.

As a Linux user, I would be very interested in doing this with
Gutenprint. I've read the documentation, but as a newbie it's hard to
tell whether Gutenprint allows this type of control. Any other options
that might be useful for *nix computing systems?
