| It's usefull to control size of canvas to make good printing, e.g. to vary aspect ratio between multiple plots of a same document.

| Unfortuntelly, GNU-Octave doesn't implement the PaperSize option like in another (non-free) software.

| I modified print.m, in order to make possible to specify canvas size to Gnuplot driver. The code is :

| +    if (!isempty (size))
| +      options = strcat (options, "size ", size);
| +    endif
|      if (! isempty (font))
|        options = strcat (options, "\"", font, "\" ");
|      endif
|       
| With this piece of code, anyone can control canvas size of Postscript driver, with a command like
| print('essai.eps', '-S2,1')

I think a better fix would be to make the papersize property work.
