A printing apparatus includes a communication interface, a user interface, a memory, and a controller. The controller is configured to, when a print instruction has been received via not the communication interface from an external device but the user interface, cancel printing of internal data stored in the memory in response to receiving a cancel instruction via the user interface. The controller is further configured to, when the print instruction has been received via not the user interface but the communication interface from the external device, continue the printing, without canceling the printing based on the cancel instruction.
