I can't really think of anything elegant. But you might be able to do
this using a listener. So, if you e.g. know that some property of the
axes always changes when you create a new plot you could do something
like (totally untested code)

  function my_listener ()
    print test.eps
  endfunction

  addlistener (gca (), "some_property", @my_listener);

I doubt this will work, though, is you need to find a property that
always changes, and I'm not sure you'll be able to find such one.
