To determine what is happening please edit __print_fltk__.m and remove the
semicolon from the end of line 149.  The resulting line is below.

  opts.pipeline = pipeline

It you don't know where to find this file, type the command below in Octave.

        strrep (which ('plot'), 'plot.m', sprintf
('private%s__print_fltk__.m', filesep))

Once the semicolon has been removed from the end of line 149, try ...

        close all
        graphics_toolkit fltk
        plot (rand (3))
        plot -depsc test.eps

And copy-n-paste everything that octave prints in its windows into your
replay to this email.

Ben:

I found and modified the opts.pipeline = pipeline line as you instructed.

I plotted my drawing that I'm having trouble with.  I then tried to print it
using the print -depsc test.eps command.  The figure window became
scrambled, Octave printed a bunch of diagonistics and then hung up.  I was
unable to copy and paste the output.

Is the problem that Ghostscript is still in a path that contains
whitespaces?

I can reinstall Ghostscript to a directory without white spaces but it will
have to wait until later today.
