#' @title Print comparisons of model parameters
#' @name print.compare_parameters
#'
#' @description A `print()`-method for objects from [`compare_parameters()`].
#'
#' @param x An object returned by [`compare_parameters()`].
#' @param engine Character string, naming the package or engine to be used for
#' printing into HTML or markdown format. Currently supported `"gt"` (or
#' `"default"`) to use the *gt* package to print to HTML and the default easystats
#' engine to create markdown tables. If `engine = "tt"`, the *tinytable* package
#' is used for printing to HTML or markdown. Not all `print()` methods support
#' the `"tt"` engine yet. If a specific `print()` method has no `engine` argument,
#' `insight::export_table()` is used, which uses *gt* for HTML printing.
#' @inheritParams print.parameters_model
#' @inheritSection print.parameters_model Global Options to Customize Messages and Tables when Printing
#'
#' @return Invisibly returns the original input object.
