best way to implement a print solution for a CF online store (at the store)

Hey everyone,

I have developed a CF web store for a client in which people order food items and then pay for it with integration with Authrorize.NET.  The customer and the store gets an email of the order.  We want to get away so that the email that gets to the sore owner is either automatically printed or that they get some notification that there is a new order there.  I have tried some software such as Namtuk Autoprint but doesn't seem to work all the time for the store owner in that it prints sometimes.  I am looking for other solutions people may have done or think can be done.  I was looking into internet printers but i know nothing about how it works or to set one up.

thanks
