Website for just eat

Ok, here’s one for you ??

I have a client who wants a new website for one of his takeaways. It will be an ecommerce site with different menu options etc. this isn’t an issue, we can do all that no problem, here’s for the bit I don’t know where to start with! Ha

Ok, they need to have the orders automatically print off when a order is made, this needs to be on a small kitchen printer really. Anyone any advise if this can be done?

Thanks ??
Jamie
