How to convert a website to a txtfile....?

Hi! I have this website with a webshop that customers can order some products. And when the products are listed up in the cart on the screen, would I like to get the output into a new txtfile and save it on the server. Then it is possible to get it faxed, and that is the goal. Anyone who has done this before? Thanks for all help! Best regards Raymond Lilleodegard
