Once the proper listeners are in place changing the paperunits and papertype 
will make this more convenient.

Presently, the following commands should do what you want.

        set (gcf, "paperorientation", "landscape")
        papersize = [30, 21]/2.54;
        set (gcf, "papersize", papersize)
        set (gcf, "paperposition", [0.25 0.25, papersize-0.5])

The last command places a 0.25in margin around the page. 

If you'd like to change the defaults for the current Octave session by ...

        set (0, "defaultfigurepaperorientation", "landscape")
        papersize = [30, 21]/2.54;
        set (0, "defaultfigurepapersize", papersize)
        set (0, "defaultfigurepaperposition", [0.25 0.25, papersize-0.5])

If you place those in our ~/.octaverc file then the defaults can be changed for 
future Octave sessions as well.
