Electronic device and printing device

An electronic device controlled by software, comprising:

• a first switch that shuts off electric power supplied via a first supply line in accordance with operation by a user;
• a second switch that shuts off electric power supplied via a second supply line in accordance with control by the software;
• and
• a delay circuit that outputs an instruction signal for shutting off electric power supplied via the second supply line to the second switch after a first delay time which is longer than a time required for a termination process of the electronic device has passed when the first switch shut off electric power supplied via the first supply line,
• wherein the delay circuit stores, as a setting value, a second delay time which is shorter than the time required for the termination process of the electronic device at a time of startup of the electronic device, and wherein,
• in a state where the software does not hang up, the delay circuit does not output the instruction signal when the first switch shut off electric power supplied via the first supply line, and
• in a state where the software hangs up, the delay circuit outputs the instruction signal to the second switch after the second delay time stored as the setting value has passed when the first switch shut off electric power supplied via the first supply line.
