GPRS Printer intergration with Wordpress Woocommerce

We got a Woocommerce Webshop on Wordpress CMS. The site is an online food-ordering type of site, so we need it to be integrated with our GPRS/SMS printer located in the kitchen of the restaurant. We need a 2-way function. Previous experience with GPRS/SMS printer integration is a big advantage. =================================== Here's how we want it to look like: 1. Customer order & pay on the webshop either: - Cash - ePay (payment gateway) 2. A receipt prints out from the printer in the kitchen where you can choose to: - Accept/decline the order - Choose what time they can expect to come and get the food (or expect the delivery time) 3. Accept the order --> customer sees on their screen that their order has been approved to [url removed, login to view] hour Decline order --> customer sees on their screen that their order has been declined because we have too many orders for now 4. The kitchen makes the food! Serious inquiries only. If you need more information or specifics, don't hesitate to let us know. We are looking for GPRS mode integration
