Integrating a GPRS/SMS printer to a WooCommerce Webshop for restaurant order printing

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! =================================== NOTE: We have already set up this function from a previous developer - the reasons we need to do this again are: 1 Completely new website (but same domain) 2 Previously used WP e-commerce --> now WooCommerce We have some files the previous developer created which you can use as a template if needed but I can't say if it would be a good template to work from. Serious inquiries only. If you need more information or specifics, don't hesitate to let us know. EDIT: We are looking for GPRS mode integration
