Print a receipt

How automatic receipt printing works after a completed sale.

Overview

After a sale is paid, the iPad lands on the Print Receipt screen and auto-prints to the connected Star (or BLE/ESC-POS) printer. The cashier sees a live preview of the receipt, can send extra copies to the printer, and can retry if the first job failed.

When to use it

  • Every completed sale โ€” the screen is reached automatically after tapping Order Paid on checkout
  • Printing a second copy for the customer before moving on to the next sale
  • Retrying manually when the first auto-print failed (out of paper, printer asleep, Bluetooth dropped)

How to use it

  1. On the payment screen, tap Order Paid to finalize the sale.
  2. The iPad navigates to the Print Receipt screen with a preview of the receipt on the left.
  3. Klu automatically sends the first copy to the connected printer โ€” if the payment was cash, the cash drawer also opens at the same time.
  4. Need another copy? Tap Print Receipt on the right side โ€” each tap sends one more copy to the printer.
  5. If the auto-print failed (no paper, printer disconnected), fix the printer, then tap Print Receipt to retry.
  6. Tap Go Home to return to the Home screen and start the next sale.

Tips & gotchas

  • The receipt layout is built for 7.2 cm thermal paper โ€” the default roll size for Star TSP100/TSP650 and most BLE ESC/POS printers.
  • Receipt content follows the current app language (EN or TH) โ€” switch languages from the drawer before printing if needed.
  • The header uses your organization name, branch address, and tax ID โ€” set those from the Dashboard Organization settings.
  • If no printer is connected, Klu still lands on the Print Receipt screen with the preview โ€” you will not be stuck, but the print button will have nothing to send to. Pair a printer from the drawer's Printers screen to fix this.
  • The screen remembers the last sale with a persistent cache โ€” if you navigate away and come back, the preview is still there, but auto-print does not fire a second time.
