Hello 

we previously use Odoo POS V14 in cafe in use order printers to send orders to bar printers

it was work smooth, the order button ( that we used to send order to printer) will be green before click on it , and when you click on it, instantly will switch to gray and will not be clickable any more 

in V15 after you click on send the button will remain green for 3-5 second (based on number of items in order ) in this 5 seconds the cashier think that he is not click it then click again, and the printer will send two times or three times to printers 

anyone face this issue ?
