1. A printing apparatus comprising:

  • a printer;

    a controller that includes at least a processor, a memory, and a sleep recovery circuit, and controls the printer; and

    a sleep recovery button that receives a user operation and causes a signal to be detected by the sleep recovery circuit in response to receiving the user operation,wherein, when an auto sleep timer value becomes zero, the controller shifts the printing apparatus to a power saving mode in which power is not supplied to the printer and the processor, but power is supplied to the sleep recovery circuit,wherein, when the sleep recovery button receives the user operation, the sleep recovery circuit detects the signal and causes power to be supplied to the processor and the memory, thereby causing the controller to;

    in a case where an operation time of the sleep recovery button is shorter than a threshold value, shift the printing apparatus from the power saving mode to a first power mode in which power is not supplied to the printer, and reset the auto sleep timer value to a default value; and

    in a case where the operation time of the sleep recovery button is longer than a threshold value, shift the printing apparatus from the power saving mode to a second power mode in which power is supplied to the printer, and reset the auto sleep timer value to an extended value different from the default value, according to the operation time of the sleep recovery button, andwherein the operation time of the sleep recovery button includes a depression time of the sleep recovery button.
