How to Print an OLD invoice (4 months ago)

[indobum]

Hello,

Is there a way to print invoices for old orders?  I have customer who purchased an item 4 months ago, and they just asked me for an invoice.  I know invoices can be sent before a buyer sends payment, and I believe you can still print an invoice when you print shipping labels.  I can find the order and look at the order details, but I don't see a way to print the invoice.  Am I looking in the wrong place?  If it is possible, could someone point out to me how to do it?

The buyer can go to his Purchase History, click on the order details link, and print the page (which is a receipt for his purchase). You can't print an invoice (which is a request for payment) after the item is paid for.
