 Кастомизация вывода

-Для полной замены логики вывода текста в конструкторе ``App`` предусмотрен параметр ``print_func``.
+Для полной замены логики вывода текста в конструкторе ``App`` предусмотрен параметр ``printer``.
 
-*   **print_func**: ``Callable[[str], None]``
+*   **printer**: ``Callable[[str], None]``
     Этот параметр позволяет передать любую вызываемую сущность (например, функцию), которая будет использоваться для вывода всех системных сообщений. По умолчанию это ``rich.console.Console().print``. Вы можете передать сюда свою функцию, чтобы, например, логировать вывод в файл или отправлять его по сети.
