Kitchen display or KOT printer: what changes on a Friday night

What a paper ticket actually costs

A KOT printer is cheap, instant and understood by everyone in the kitchen. It also produces an object that can be dropped, stuck to a wet surface, taken by the wrong station, or fall behind the counter at eight in the evening and be found at eleven.

The real cost is not the lost ticket, which happens rarely. It is that paper answers no questions afterwards. How long did that table wait. Which station is behind tonight. Which dish always takes longer than the kitchen thinks it does. A printed ticket has no memory, so the argument the next morning is between two people who both remember it differently.

What a screen gives you that paper cannot

Four things, and only the first is obvious.

• •The ticket cannot be lost, and it cannot be quietly thrown away when a dish is forgotten
• •Every item carries a clock, so slow tickets rise to the top by themselves instead of by somebody noticing
• •Items route to the station that cooks them, so the tandoor sees tandoor items and not the dessert
• •At the end of the week you have timings, which is the only honest basis for changing a menu or a shift

Where screens go wrong

Most kitchen display failures are installation failures rather than software ones, and all of them are predictable.

• •One screen for a kitchen with three stations, so everyone crowds the same corner
• •A screen placed where the light hits it, or where a hand covered in oil has to touch it
• •No fallback. If the power or the internet goes and no printer is left in the building, service stops. Keep the printer even after you stop using it daily.
• •Bumping a ticket that is not finished, because the button sits next to the one that scrolls

When a printer is still right

A single-station kitchen with one cook does not need timings on a screen to know what is late. Neither does a takeaway counter where a ticket lives for four minutes.

The switch earns its place when there is more than one station, or more than one person deciding what to cook next. Below that a printer is not a compromise, it is the correct answer, and the money is better spent elsewhere.
