By default size, do you mean ...

        close all
        graphics_toolkit fltk
        plot (rand (3))
        orient tall
        print foo.pdf

Or do you mean all the above *except* "orient tall" ?

If the former, then you'll need to have a screen that is able to render a 
figure that is 10.5*72 pixels high. If the latter, then you'll need a screen 
with room for a figure that is 6*72 pixels high.

I mean you can output a smaller image/page, and then scale the result using 
ghostscript (or some other utility outside of octave).
