Food ordering app: working offline

[Damazo]

I built a food ordering app on appsheet. I can register perfectly what the client ask and send printing via email, so app need internet connection every moment to finally get an ordering receipt.

I work on a restaurant and I built apps on my free time, so I can give a solution in my job. 

We are in rainy season, so internet connection problems are common and every minute new orders are required.

I set up offline options in appSheet but I can't get a receipt due an internet connecction failure.

¿Has anyone implemented a similar app? ¿how I cant print on a local network? ¿how I can do my app complete offline?  Thany you for response community

AppSheet requires an internet connection to do anything beyond the user interface of the app.

There is no way AppSheet can use a local printer.

The only thing I've seen for printing offline via AppSheet is by using a local php server that receives data via URI parameters that can be created as any normal URL on AppSheet, and just works with thermal printers afaik
