Another (low-level) way to do this is to load emaxima.lisp and set
dispaly2d to emaxima.

(%i2) load("emaxima.lisp");

(%o2) "emaxima.lisp"
(%i3) display2d:'emaxima;
(%o3) \mathrm{emaxima}
(%i4) integrate(x^2,x);
(%o4) {{x^3}\over{3}}
(%i5) diff(sin(x),x);
(%o5) \cos x
(%i6) diff(cos(x),x);
(%o6) -\sin x

It is pretty straightforward to convert that output into the
maximasession data you get from using emaxima-mode.
