The Tebi App will notify you when a printing error has occurred, with extra information about the cause — for example: "the printer has run out of paper or is switched off."
What you'll see
A red printer icon appears in the bottom-left of the device that placed the order. Tap it to see the error, ignore it for a while, or go to the prep station to see which tickets failed.
On the prep station itself, each ticket shows whether it printed successfully — visible on any device.
How to fix it
Tap the printer button on the prep ticket to reprint it once the issue is solved.
Or use the retry all failed tickets button at the top-right of the prep station.
If a device controlling a prep station printer goes offline, it will ask whether to reprint or skip any missed tickets once it's back online.
