I'm currently trying to use the POS system on odoo.sh for my restaurant. I really favor all features in odoo.sh. Absolutely great.

I've looked around documents described the print-outing to tell the order to a kitchen, but I could not found that. I've might wrong to use search keywords. I would like to know the architecture and overview of a network between our local printer and odoo.sh, and network communication requirements of IoT Box because there is a firewall inside our restaurant.

There is some description of IoT Box, however, I do still not understand what features inside the box. Is this able to work as a proxy between our local printer and odoo.sh and to send the document's data and print it out?

If you already know some good materials or tutorials to explain about that, please let me know. I'll learn that. Thanks!
