Print Order Confirmation as Guest

This module allows guest users to print their order confirmation on the order complete/success page in Magento.

Magento does not allow guests to print orders due to the simple nature of the print order URL out of the box, example: http://www.example.com/sales/order/print/order_id/49/  

This URL could be easily modified to view other users order information by changing the value after "/order_id/".

To prevent this from occurring Magento only allows logged in users to see the print order button and checks for user to order correlation.

This module creates a secure URL for each guest order and prevents cross order lookup.  Example URL from the module: http://www.example.com/guest/order/print/order_hash/ d69d3401d01a8ceed4549434e5ad9f40/

The printable order page is managed in exactly the same manner as the out-of-box printable order page for logged in users.
