POS connected with themal printer Is Possible With Glide?

I want to know if i can build a pos system for a client who own a bar an room reservation for moment with glideapp. what are the contrainte or what possible is anyone made a project like this before

When it comes to integrating with external devices, the general rule of thumb is as long as that device has an API that you can communicate with, then yes it’s possible.

Not possible with Bluetooth?

or if the device is connected to a printer?

This could be a great solution: trigg webhook by APi
In the case of POS, tens of thousands of requests are implied, if not hundreds, and $ 0.02 for printing a label is expensive. I just open the label printing window and the user needs to click the print button in the system dialog. All other methods with automatic label printing require additional payment. If someone manages to find a way to automatically send for printing, printing without additional financial costs, I would be very interested to know this method.
An approximate direction is to access the local deployed print server via js column. But so far I have not been able to find an easy solution.
