Parameters ========== pretty_print : bool, default=True If ``True``, use :func:`~.pretty_print` to stringify or the provided pretty printer; if ``False``, use :func:`~.sstrrepr` to stringify or the provided string printer. order : string or None, default='lex' There are a few different settings for this parameter: ``'lex'`` (default), which is lexographic order; ``'grlex'``, which is graded lexographic order; ``'grevlex'``, which is reversed graded lexographic order; ``'old'``, which is used for compatibility reasons and for long expressions; ``None``, which sets it to lex. use_unicode : bool or None, default=None If ``True``, use unicode characters; if ``False``, do not use unicode characters; if ``None``, make a guess based on the environment. use_latex : string, bool, or None, default=None If ``True``, use default LaTeX rendering in GUI interfaces (png and mathjax); if ``False``, do not use LaTeX rendering; if ``None``, make a guess based on the environment; if ``'png'``, enable LaTeX rendering with an external LaTeX compiler, falling back to matplotlib if external compilation fails; if ``'matplotlib'``, enable LaTeX rendering with matplotlib; if ``'mathjax'``, enable LaTeX text generation, for example MathJax rendering in IPython notebook or text rendering in LaTeX documents; if ``'svg'``, enable LaTeX rendering with an external latex compiler, no fallback wrap_line : bool If True, lines will wrap at the end; if False, they will not wrap but continue as one line. This is only relevant if ``pretty_print`` is True. num_columns : int or None, default=None If ``int``, number of columns before wrapping is set to num_columns; if ``None``, number of columns before wrapping is set to terminal width. This is only relevant if ``pretty_print`` is ``True``. no_global : bool, default=False If ``True``, the settings become system wide; if ``False``, use just for this console/session. ip : An interactive console This can either be an instance of IPython, or a class that derives from code.InteractiveConsole. euler : bool, optional, default=False Loads the euler package in the LaTeX preamble for handwritten style fonts (http://www.ctan.org/pkg/euler). forecolor : string or None, optional, default=None DVI setting for foreground color. ``None`` means that either ``'Black'``, ``'White'``, or ``'Gray'`` will be selected based on a guess of the IPython terminal color setting. See notes. backcolor : string, optional, default='Transparent' DVI setting for background color. See notes. fontsize : string or int, optional, default='10pt' A font size to pass to the LaTeX documentclass function in the preamble. Note that the options are limited by the documentclass. Consider using scale instead. latex_mode : string, optional, default='plain' The mode used in the LaTeX printer. Can be one of: ``{'inline'|'plain'|'equation'|'equation*'}``. print_builtin : boolean, optional, default=True If ``True`` then floats and integers will be printed. If ``False`` the printer will only print SymPy types. str_printer : function, optional, default=None A custom string printer function. This should mimic :func:`~.sstrrepr()`. pretty_printer : function, optional, default=None A custom pretty printer. This should mimic :func:`~.pretty()`. latex_printer : function, optional, default=None A custom LaTeX printer. This should mimic :func:`~.latex()`. scale : float, optional, default=1.0 Scale the LaTeX output when using the ``'png'`` or ``'svg'`` backends. Useful for high dpi screens. settings : Any additional settings for the ``latex`` and ``pretty`` commands can be used to fine-tune the output.

Note that before the ``init_printing`` command is executed, the LaTeX rendering is handled by the IPython console and not SymPy. The colors can be selected among the 68 standard colors known to ``dvips``, for a list see [1]_. In addition, the background color can be set to ``'Transparent'`` (which is the default value). When using the ``'Auto'`` foreground color, the guess is based on the ``colors`` variable in the IPython console, see [2]_. Hence, if that variable is set correctly in your IPython console, there is a high chance that the output will be readable, although manual settings may be needed. References ========== ..
