Abstract
A printer has an electric power supply controller which controls electric power supplied to an indicator indicating a state of the printer so as to prolong a driving time of the printer, which is driven by a battery. When the apparatus is set to an on-line state using an on-line key, electric power is initially supplied to an on-line LED, which indicates the apparatus is in the on-line state. Afterwards, when a predetermined time period has passed, the supply of electric power is cut off to the on-line LED, whereby the consumption of electric power supplied to the indicator can be minimized.
