The bill saved but nothing printed, or the till reports that the printer cannot be found.
Check in this order
1. Is the printer powered and has paper? Obvious, and it is the cause more often than anything else. Check the paper roll is seated correctly and the cover is fully closed.
2. Is the printer on the same network as the till? Network printers must be on the same local network as the desktop till. If the printer is on a guest network or a different Wi-Fi band, the till cannot reach it.
3. Has the printer’s IP address changed? This is the most common real cause. If the printer gets its address automatically, the router can hand it a different one after a power cut — and the till is still looking at the old address.
Fix it properly by giving the printer a static IP address on the router, then updating it in print settings. Otherwise this will recur every time the power goes.
4. Is it configured for the right station? If receipts print but kitchen tickets do not, the category-to-station mapping is probably incomplete. Items in a category with no station mapped have nowhere to print.
5. Test directly. Print a test page from print settings. If the test works and real orders do not, the problem is the mapping, not the printer.
If it still fails
Restart the till application, then the printer, then the router — in that order.
If the problem persists, email admin@aesoni.in with the branch name, printer model, and whether the test page works.
