There isn't any way to suppress the display of input and result. In the
realm of shameful hackery, you could try this: put the following
(defun displa (x) (declare (ignore x)))
in your maxima-init.lisp file. Then neither input nor result will be
displayed. However, the effect on interactive sessions might be
unhelpful.
Less shamefully, recall that tex takes an optional argument which
specifies a file or stream to which to write the TeX output. Just
write the TeX stuff to a file and forget about display flags.
If you are writing a system to replace Maxima's usual input/output
system, there have been several such projects, including some which
diplay TeX output. You might be able to reuse some of their code. What
are you working on?
