There are a few possibilities as to why your printer may suddenly stop working as intended:

1. Printer is not printing

• The thermal receipt paper roll has run out.

• The printer cover is not fully or properly closed, check for error messages.

• Device is on airplane mode, causing the printer to be disconnected.

2. Printer is printing, but the receipt is blank

• Thermal paper may be inserted on the wrong side.

• Paper roll used is not thermal paper.

3. I am unable to open my printer cover

• Check that the printer knife is not revealed causing a blockage, this is usually caused by prematurely pulling out the receipt before the machine cuts it.
