I need to add another field to the Invoice output. Of course, right now it gives us:

Products Model Tax Unit Price Total
etc.

I need to add an additional output. It is similar to the product model, but will in fact be a scan-able bar code for each product. This will allow our company to scan each item purchased thereby letting the shop floor know what items go into each car order. see us at: www.kirkhammotorsports.com/cart

I have spent a few hours on here searching for the solution, a few threads came close, but, maybe what I need is to add an extra filed to the products entry page so I can define the bar code for each item individually. I also need to know where the output gets defined so I can tell the code to use a bar code font.

Any help is most appreciated!! Let me know if I need to clarify more.

Thanks!
