Sure, that means that you're using the latex printer (as opposed to the string printer or the pretty printer). In this case, it's even easier for you, because this behavior has been fixed already to do it the way that you want in the git master. So you just need to work off the SymPy development version until the next release. See https://github.com/sympy/sympy/wiki/Getting-the-bleeding-edge.
