The above works for 3.0.x, but will not work for the more recent 3.2.x builds.

Octave's development has been progressing toward compatibility with Matlab. 
However, it is not there yet. The commands below will produce a plot with 10pt 
fonts for the axis tick labels and for the ylabel. The xlabel will be size 16.

        x = 0:10;
        plot (x, x)
        set (gca, "fontsize", 20)
        xlabel ("fontsize=16", "fontsize", 32)
        ylabel ("fontsize=10", "fontsize", 20)
        print -depsc foo.eps

The fontsizes are set to twice the targeted values as the gnuplot eps terminal 
scales the fontsize down by a factor of two (this is intentional, and not a 
bug).
