It depends on the printer, but for str(), this is implemented in
sympy/printing/str.py, line 44 (_print_Add).
If you look on top, you will see:
_default_settings = {
"order": None,
"full_prec": "auto",
}
These should be possible to set by the user. But for some reason I
can't figure out what to use for "order" to change the ordering.
Summary: it should be possible, and if not, it should be quite easy to fix.
