Add print button to the bank transfer confirmation

Hi,
There is no option for that but they can easily print it with the print button of their browser.

If you turn on the "Payment of orders not paid immediately" option of the configuration, the users will be able to click on a "pay now" button on their order listing in order to see again that page.

Also, you can add the information in the order creation email. you can edit it via the menu System>Emails in the Business edition.
