It's in the same manual. It may be a bit tougher to do however, as you will need a PHP script that receives the payment info.

Return URL – Let people return to a page on your website if they click a return link or button on the PayPal payment confirmation page.

Auto Return – Have PayPal return people automatically to a page on your website. Important: PayPal recommends that you turn Payment Data Transfer on when you turn Auto Return on. With Auto Return on, PayPal redirects people to your website from an alternative PayPal payment confirmation page that does not display a View Printable Receipt link, so people cannot print PayPal payment receipts. Payment Data Transfer provides the transaction information that you need to let people print receipts from your website.

To learn more, see Auto Return.

Payment Data Transfer – PayPal includes information about the completed transaction when you use a return URL or Auto Return to send people back to your website. Use the information that Payment Data Transfer provides to display a “thank you, print your receipt” page on your website.

To learn more, see the Payment Data Transfer page on Developer Central.
