Why route tickets at all
In a small kitchen one printer can be enough: the cook reads the whole ticket and makes everything. Once there are two or more stations, a single ticket means someone has to read it aloud, tear it or copy it, and items get missed. Routing prints each part of the order where it is made. The fryer sees two fries; the grill sees two burgers; the bar sees the drinks.
Routing also speeds up drinks. Sending drink tickets straight to the bar means drinks reach the table while the kitchen is still cooking, rather than after the server walks the ticket over.
Plan stations and the expo copy
Walk the line and write down every station and what it makes. Most menus route cleanly by category: Burgers to the grill, Sides to the fryer, Salads to the cold station, Desserts to pastry, Drinks to the bar. A few items need special handling, for example a salad with grilled chicken that needs both the grill and the cold station.
Decide whether the expo or pass needs a full copy of every order to call tables and check plates. Many kitchens print a full ticket at the pass in addition to the station tickets; others use a kitchen display at the pass.
Hardware that survives a kitchen
Kitchen printers live near heat, grease and steam. Mount them off the counter, away from fryers and dish machines, and use models built for kitchens. Thermal paper darkens near heat, which is why some kitchens use impact printers at hot stations.
Connect kitchen printers by Ethernet where you can and reserve a fixed IP address for each one in the router. A printer that changes address after a power cut is the most common reason tickets stop printing mid-service. Label each printer with its station name and IP address.
Test, and plan for failure
Ring a single order with one item from every category and check each station. Then try the edge cases: a modifier with a long note, an item added to an existing order (only the new item should print), and an item moved from one table to another. Finally, unplug a printer and see what happens, so staff know how to reprint and where to send tickets if a printer dies on a Friday night.
Doing it in SeroPOS
In SeroPOS routing is called KOT Mapping. It lives in the app's side drawer and in the back office under Settings, then KOT. It is hidden in Retail Mode.
- Side drawer, then Add/Edit Printer: add each kitchen printer (Network is recommended, IP and port 9100), set the paper width, and press Test Printer. Auto-detect scans Bluetooth, USB and the Wi-Fi network.
- Side drawer, then KOT Mapping, then ADD KOT: give the station a unique name and choose its printer.
- Pick the categories, products or food types (Veg, Non Veg, Eggitarian, General) that should print there; use Select all or Clear to speed it up.
- Settings: turn on Print KOT. Holding an order or pressing KOT prints the tickets.
- To use a screen instead of paper, turn on KDS Mode on a tablet or PC at that station; station chips filter the board.
- When a held order is resumed and changed, the new ticket carries only new or increased items. KOTs also print when the till is offline.
