def fl_object_ps_dump(ptr_flobject, fname):
    """fl_object_ps_dump(ptr_flobject, fname) -> result

    Finds out hardcopies of some flobjects in a what-you-see-is-what-you-get
    (WYSIWYG) way, especially those that are dynamic and of vector-graphics in
    nature. It outputs the specified flobject in PostScript. The flobject must
    be visible at the time of the function call. The hardcopy should mostly be
    WYSIWYG and centered on the printed page. The orientation is determined
    such that a balanced margin results, i.e., if the width of the flobject is
    larger than the height, landscape mode will be used. Further, if the
    flobject is too big to fit on the printed page, a scale factor will be
    applied so the flobject fits. The box underneath the flobject is by
    default not drawn and in the default black&white mode, all curves are
    drawn in black.

    Parameters
    ----------
        ptr_flobject : pointer to xfdata.FL_OBJECT
            object. Only the xfdata.FL_XYPLOT flobject is supported.
        fname : str
            name of output file. If it is empty (""), a fselector will be
            shown to ask the user for a file name.

    Returns
    -------
        result : int
            0 (on success), or -1 (on errors)

    Examples
    --------
        >>> if fl_object_ps_dump(pxyplobj, "myhardcopy.ps") < 0:
        >>> ... <something>
