Qz tray self certificate and so when we use odoo on the web to print the warning is not asked on the point of sale to allow printing.

When using the pos order system, we should be able to print the item to be prepared to the printers respectively for kitchen and bar.

We use qz tray to connect the thermal network printers. Everytime odoo tries to print, the connection needs to be manually connected and a pop up keeps coming for allow to trust.
