The POS reports a successful print, but nothing reaches the screen. Work through these in order — the first two account for most cases.
1. Is the Virtual Printer running?
Look at the VP indicator in the sidebar. A green dot means running.
A red dot, or the red banner reading Virtual Printer is not running — POS orders won't be received, means it has stopped. See "Virtual Printer is not running".
2. Has the display's IP address changed?
This is the most common cause by a distance, and it usually happens after a power cut or a router restart.
Open Settings → Virtual and compare the address shown there with the one configured in the POS. If they differ, the POS is sending orders to an address nothing is listening on.
Fix it properly rather than just updating the POS: give the device a static IP address or a DHCP reservation on the router, so it cannot drift again.
3. Are both devices on the same network?
The POS and the display must be on the same network. Check that the tablet has not joined a guest network, or dropped to mobile data.
4. Is anything routed to that printer?
A printer that exists but has no categories assigned receives nothing. In the POS, confirm that the kitchen categories are routed to the printer you created for the screen.
On Uniwell MGP, check that departments and PLUs are assigned to the right KP number — see Connect a Uniwell MGP POS.
5. Is every item on the order routed elsewhere?
If a sale contains only drinks and the screen is set up for food, nothing arrives — correctly. Try a test order containing an item you know is routed to this screen.
Still nothing
