I assume you're just wanting to suppress output to a window? If not, can you describe what behavior it is you desire?

If you'd like to suppress displayed output, you can begin our Octave session with

    set (0, "defaultfigurevisible", "off")

That will suppress output to a window, but the print command will still work.
