Set Up Automatic Multi-Printer KOT Printing

Multi KOT Print is the automated kitchen-print service in the Posnic desktop app. Enable Restaurant/KOT, install each printer in the operating system, identify the branch, select the printers and keep polling active during service.

Prerequisites

  • Use the installed Posnic desktop app. Multi KOT Print depends on Electron printer access and is not a browser-only feature.
  • Enable Restaurant/KOT in Settings -> Features, then restart or reopen Hardware Manager if its tab is not visible.
  • Install and test every kitchen printer in Windows, macOS or Linux before selecting it in Posnic.
  • Know the exact branch ID whose kitchen queue this machine should monitor.
  • Keep the POS API reachable. On the till itself, use the app-filled API address; edit it only when a dedicated kitchen PC is polling another till.
  • Use a stable wired or local network connection and prevent the kitchen PC from sleeping during service.

Configure the Kitchen Print Service

  1. Open the Posnic desktop app and open Hardware Manager.
  2. Choose the Multi KOT Print tab. If it is absent, confirm Restaurant/KOT is enabled and reopen the manager.
  3. Review API URL. Leave the app-filled local address unchanged on the till computer.
  4. Enter the Branch ID that owns the restaurant orders.
  5. Click Load Printers.
  6. Check every printer that should receive the same KOT. The operating-system default is marked in the list.
  7. Click Start KOT Polling.
  8. Wait for the success message stating that the service is listening every five seconds.
  9. Confirm Live Status shows Polling, the expected branch and every selected printer.
  10. Create one test KOT, save it and verify one legible ticket arrives at every selected station.

What Is Saved and Restored

Hardware Manager saves the branch and printer names on the desktop computer. When a complete configuration exists, opening the Multi KOT Print surface restores polling automatically. The API address is resolved from the current app process so an old saved local port does not silently break printing after an update.

  • Printer selection is locked while polling is active.
  • Stop polling before changing printers, branch or connection details.
  • A renamed, removed or disconnected operating-system printer must be loaded and selected again.
  • Each kitchen computer has its own local configuration and logs.

Opening Checklist for Every Shift

  • Desktop app and Hardware Manager are running.
  • Live Status says Polling.
  • Last Poll updates instead of remaining stale.
  • Branch matches the serving location.
  • Printer list matches the stations needed today.
  • Paper, cover, power and network/USB connection are ready.
  • A test KOT prints once at each expected station.

Restaurant Start a KOT A KOT records preparation work before settlement. Choose dine-in or takeaway, identify the table and PAX, add the real menu items, review the cart and save the order. Restaurant Manage Active KOT Select the table or TA tile to work the live order. Review the order before each action because kitchen changes and final billing have different consequences. Restaurant Kitchen Print Logs The kitchen queue labels changed order states, keeps a daily local print log and supports controlled reprints. Use the KOT number, order identity and print type together so the kitchen does not prepare duplicate or cancelled items.
