Abstract
The disclosure discloses a printer includes an error occurrence detecting portion, an interruption control portion, a switching portion, an error storage portion, and a display control portion. The error occurrence detecting portion detects occurrence of an error event. The interruption control portion interrupts a printing process. The switching portion performs switching to a supply shutoff state or a low power consumption state. The error storage portion stores contents of the error event corresponding to the interruption when the switching portion performs the switching. The display control portion controls the display device to display an error display screen representative of the contents of the error event stored in the error storage portion in the case that a return to a normal power supply state.
Claims8
A printer comprising:
- a plurality of operation mechanisms that includes a feeder configured to feed a print-receiving medium, a printing head configured to form a desired print on said print-receiving medium, and a display device configured to perform desired display, the plurality of operation mechanisms being configured to be operated by a supplied power source voltage;
- an accepting portion configured to accept a printing instruction;
- an operation control portion configured to control said plurality of operation mechanisms in accordance with said printing instruction accepted by said accepting portion so as to sequentially execute a printing process onto a predefined amount of said print-receiving medium;
- an error occurrence detecting portion configured to detect occurrence of an error event related to an operation of at least one of said plurality of operation mechanisms;
- an interruption control portion configured to interrupt a printing process onto said predefined amount of said print-receiving medium corresponding to said printing instruction in a case that said error occurrence detecting portion detects occurrence of said error event during said printing process;
- a switching portion configured to perform switching to a supply shutoff state or a low power consumption state of said power source voltage, the switching being triggered by an elapsing of a reference amount of time after said interruption control portion interrupts said printing process;
- an error storage portion configured to store contents of said error event corresponding to said interruption when said switching portion performs the switching to said supply shutoff state or said low power consumption state;
- and
- a display control portion configured to control said display device to display, upon detecting that a return to a normal power supply state is made by a return operation after the switching by said switching portion, an error display screen specific to said error event that occurred prior to switching to the supply shutoff state or the low power consumption state and stored in said error storage portion.

- and
- an error elimination detection portion configured to detect elimination of said error event corresponding to the interruption during said supply shutoff state or said low power consumption state after the switching by said switching portion,
- wherein, in the case that the return to said normal power supply state is made after said error elimination detection portion detects the elimination of said error event, said display control portion controls said display device to display the elimination of the error event along with the contents of said error event on said error display screen.
