Printers and hardware

Receipts will not print

Receipts print through the browser's print dialog. If nothing appears, the problem is between the browser and the printer rather than in the platform — check the machine can print a test page.

The scanner is not scanning

A scanner behaves like a keyboard. Open a text field and scan: if characters do not appear, the scanner is not paired. If they appear but no product is found, the barcode is not recorded against a product.

The card terminal is not responding

For Square, check the device is still paired to the store. A checkout that has stalled can be cancelled from the POS rather than left on the device. See Square Terminal.

The drawer will not open

Drawers that open from a receipt printer depend on that printer working — fix printing first.
