imaxima

It runs a maxima repl in emacs, producing output in latex, and can
export the whole session to a latex buffer for editing.

maxima.el has such facilities.

Try imaxima.el, I think it does much of what you want.

Aside from merging Fermin's work back into Maxima's source tree, what is
on my todo list is improving ob-maxima for org-mode integration, with
the aim of providing a "workbook"-like experience. The current ob-maxima
lacks many features...
