Toast POS skipping orders or printing duplicate kitchen tickets — KDS missing orders, printer mapping, integrations

Technician

Hey! We’ll stop the Toast POS duplicate tickets problem and make sure no orders are skipped on the KDS or printers. Tell me what’s missing on the KDS screen, on kitchen order printers, or in Expo. Also note if online ordering (DoorDash, Uber Eats) is arriving twice or not at all.

Customer

We use online ordering with DoorDash. One order came in twice; another didn’t print to the Grill printer. KDS showed it only once, and our Expo screen skipped an order. We also reprinted from Order History and it printed two chits.

Technician

Got it. Duplicate kitchen tickets or missing KDS orders in Toast usually come from:
• Printer routing rules that overlap (e.g., same item routed to KDS and printer twice).
• Online‑ordering integrations configured to auto‑fire to multiple stations.
• KDS filters / screen holding items (Expo batching/throttling) or Auto‑fire disabled.
• Offline tablet / network drops causing a re‑send when the device reconnects, which looks like duplicates.
• Reprints from Order History plus auto‑reprint in the queue. We’ll check each area.

Customer

How do we check the routing and the Expo screen? I don’t want two chits for burgers again.

Technician

Verify Toast kitchen printer & KDS routing:
1) In Toast back office go Printers & KDS → Printer Routing and KDS → Kitchen Mappings.
2) For each menu group (e.g., Grill/Salads/Expo), confirm there’s a single destination per item. If an item routes to two places, that’s a duplicate mapping.
3) Check Item‑level routing rules and Modifiers — avoid duplicating to Station and Destination simultaneously.
4) Print a Test Ticket per category to confirm mapping.

Customer

KDS misses orders, printer gets them, and Expo sometimes shows nothing during a rush. The Grill printer also jammed.

Technician

KDS missing orders — steps:
• On each KDS go to Device Settings → KDS Filters and ensure the correct menus and tags are visible.
• Check Hold/Auto‑fire (strong rush settings can queue new tickets).
• Reboot the KDS and confirm it’s online in Toast Device Manager; stale sessions can miss updates.
• If a printer jam is involved, enable Kitchen Alerts and set the Toast order to show a single source. Queue retries can look like duplicates when the printer comes back.

Customer

Could DoorDash/Uber Eats be creating duplicates or skipping a ticket?

Technician

Yes, integrations can duplicate online orders or skip lines if modifiers aren’t mapped. Do this:
• In Integrations → Partner settings, ensure you use either the native Toast integration or your aggregator — not both.
• Normalize item/modifier names to avoid crossover (e.g., “Burger – No Lettuce” = same in both systems).
• After a catalog change, re‑sync menus for DoorDash/Uber Eats and Toast.

Customer

What about the network or tablets? We saw the FOH tablet freeze and then a bunch of tickets reprinted.

Technician

Offline events (not Wi‑Fi roaming quality) can cause the queue manager to retry prints when the connection returns, which looks like duplicates. Actions:
• Put the printers and KDS on a wired VLAN where possible; disable tablet power‑saving.
• Clear the Kitchen Printer Queue and print a test chit from one device while the queue remains stable.
• Export system logs if the issue persists — we’ll review for drop/retry patterns.

Customer

Great, we corrected two duplicate mappings and rebooted the KDS. Orders look normal now. Can you summarize a fix I can share with the team?

Technician

Summary: If Toast skips orders or prints duplicate kitchen tickets, audit Printer Routing & KDS mappings for overlap, re‑sync online‑ordering integrations, verify KDS filters / auto‑fire, and stabilize the network. Need hands‑on help? Open the chat — we’ll tune your Toast setup end‑to‑end.

Quick answer: the accepted fix

Accepted fix for Toast POS duplicate tickets / skipping orders: remove overlapping printer routes and conflicting KDS mappings, re‑sync DoorDash/Uber Eats integrations, confirm KDS filters & auto‑fire, and keep printers/KDS on a reliable network.

FAQ

Step‑by‑step (Toast back office)

1. Open Printers & KDS → check Printer Routing and KDS Kitchen Mappings for overlap.
2. Normalize item/modifier names; ensure each item maps to one destination only.
3. Re‑sync online‑ordering integrations (DoorDash/Uber Eats) and disable duplicates paths.
4. On devices, verify KDS filters & auto‑fire, then print test orders for each category.

Device/network hygiene

1. Prefer wired Ethernet for printers/KDS; isolate POS Wi‑Fi; disable power‑saving on tablets.
2. Clear jammed queues before reprints; avoid auto‑reprint when troubleshooting.
3. After changes, reboot devices and confirm in Toast Device Manager.
