Can init_printing() be forced to print mathjax/latex in a "dumb" console?

[singlets]

(Probably a newbie question here, but not finding it in ggroup or docs)

Can I convince init_printing() to give the mathjax/latex representation of an expression in an IPython terminal session without using latex(expr)?

For example (Anaconda/python3, linux, sympy 1.0 in an xterm or emacs console):

from sympy import *
init_printing(use_latex='mathjax')
var('x')
expr = x**2
expr

desired output:
x^{2}

I have tried various options to init_printing() like use_latex=True, use_latex='mathjax', 'matplotlib', etc., but sympy falls back to simple forms (str, pretty-printers) unless in a qtconsole or notebook. I must be misunderstanding how init_printing() works (or maybe there's another approach I should be using?).

Motivation: I'm using org mode and it's support for mathjax/latex to generate content that can be migrated directly into Jupyter notebooks. I'm hoping to avoid translating latex(expr) into expr everywhere.

Thanks,
Steve

I believe you can set str_printer=latex.

I gave this a go with no joy:

In [1]: from sympy import *

In [2]: init_printing(str_printer=latex)

In [3]: var('x')
Out[3]: x

In [4]: x**2
Out[4]:
 2
x

Thanks,

But this looks promising:

In [2]: from sympy import *

In [3]: init_printing(pretty_printer=latex)

In [4]: var('x')
Out[4]: x

In [5]: x**2
Out[5]: x^{2}

Thanks for pointer,
Steve

I see. I guess for str_printer to work you need
init_printing(str_printer=latex, pretty_print=False). I would at least
expect str_printer to change the output of str(), but it doesn't seem
to affect it.
