What is WordPress Hook: admin_print_scripts-{$plugin_page}
The admin_print_scripts-{$plugin_page} hook in WordPress is used to add scripts to the admin section of a specific plugin page. This hook allows developers to enqueue scripts that are only necessary for a particular plugin page, rather than loading them on every admin page.

The admin_print_scripts-{$plugin_page} hook is located within the admin-header.php file, which is included in the admin section of WordPress. It is specifically designed to target a plugin page and enqueue scripts that are required for that page only. This ensures that unnecessary scripts are not loaded on other admin pages, improving performance and reducing conflicts with other plugins.
