Octave's pdf output size is controlled by the figure's "papersize" property.  
Meaning pdf output is a full page.  The placement of the figure on the page is 
controlled by the "paperposition" property.  If you just want a figure then you 
can either (1) adjust the figure's "papersize" and "paperpostion" properties, 
or (2) If you are using Octave 3.6.x, try using the pdfwrite device.

(1) To adjust the figure properties ...

        close all
        figure (1)
        set (gcf, "papersize", [6, 4], "paperposition", [0 0 6 4])
        plot (rand (3))
        print test1.pdf

(2) Use pdfwrite

        close all
        figure (1)
        plot (rand (3))
        set (gcf, "paperposition", [1.25 3.5 0 6 4])
        print -dpdfwrite test2.pdf
