Advanced Titles

I believe the appropriate function is <?php post_type_archive_title(); ?>

But personally I pull in the whole post type object in case there’s anything more than the title I need

$post_type = get_post_type();
		$post_type_object = get_post_type_object($post_type);
		echo $post_type_object->labels->name;

If you do a print_r($post_type_object) you can see all the data you get.
