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.
