All transactions made on any device logged into your account will show up as a transaction on all devices. Now if you are looking for it to pop up on the display it won't for standard POS, but there is a Square for Kitchens that is exactly made for orders going to a kitchen. you can also have it just automatically print orders. You would need someone more experienced in kitchen setups as I don't use those parts of Square in my Garden Center.
