I am developing an application for taking orders in restaurants by scanning a QR code. for this, when the customer validates their order via their phone, I need a receipt to come out of a thermal printer.
For this I therefore have several problems:
- To be able to format the information that I print
- Connect 1 or 2 printers per restaurant easily
- Ensure that the ticket goes out immediately without requiring a computer.
If you have a solution, that would be really great!!
Thanks in advance.
