From PayPal you could just print the transaction details page and give that to them as the receipt.
If you are using PayPal Here it would give you a better formatted receipt.
The PayPal Invoicing system would provide a nice looking invoice / receipt for the whole process and could be managed within PayPal on both sides.
Another option would be to provide a basic receipt of your own with a simple template in MS Word or Google Docs or something like that.
When the person made their payment, PayPal would have sent them a basic email about it as well. They could have used that as their receipt.
Lots of options!
