Один HTML-код — две версии сайта Интернет повысил доступность информации многократно, но не отменил книги, учебники, газеты. Информация, представленная на бумаге, как и прежде, нужна. Поэтому я вижу смысл в том, чтобы обеспечить обратную связь, т.е. переход сетевых материалов на бумагу. Тем более, что это сделать просто. Для этого вам не нужно дублировать информацию специально для печати. Правда, ваш сайт долежен удовлетворять условиям: HTML-код ваших страниц свободен от оформительского кода, т.е. внешнее оформление сайт получает с помощью CSS — каскадной таблицы стилей. В таком случае работа по созданию печатной версии не займет у вас более 5 минут. Шаг #1. Ваш сайт уже имеет версию для вывода на экран. Необходимо добавить в эту строчку media="screen". Теперь строчка выглядит так: <link rel="stylesheet" type="text/css" media="screen" href="css/stylе.css" /> Шаг #2.
