Paypal standard is available on the
standard checkout, that means your customer will register on your shop
and use that account to make an order, all done on your page, they get
redirected to paypal only to authorise the payment.
Paypal Express checkout bypasses the registration process. There is a
special button on the login page that allows your customers to checkout
using their paypal account only. All the information like the shipping
and billing address is sent to us from paypal.
Please note that due to technical limitations imposed by the nature of
the Express Checkout process, you will need to setup shipping on your
paypal account as well as your admin panel.
