    Initializes pretty-printer depending on the environment.

    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 (https://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.

    >>> init_printing(order='old') # doctest: +SKIP
    >>> str(x**2 + y**2 + x + y) # doctest: +SKIP
    x**2 + x + y**2 + y
    >>> init_printing(num_columns=10) # doctest: +SKIP
    >>> x**2 + x + y**2 + y # doctest: +SKIP
    x + y +
    x**2 + y**2

    Notes
    =====

    The foreground and background colors can be selected when using ``'png'`` or
    ``'svg'`` LaTeX rendering. 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.
