    • An interrupt control apparatus includes: an interrupt request supply unit that supplies interrupt request information; a processing unit that performs interrupt processing based on the interrupt request information supplied by the interrupt request supply unit; and a time measuring unit that is used to measure an elapse of a predefined time period from a time point when the interrupt request supply unit starts to supply the interrupt request information, wherein: even if new interrupt cause information is stored during the time when the time measuring unit is measuring the elapse of the predefined time period, the interrupt request supply unit does not supply interrupt request information based on the new interrupt cause information to the processing unit; and after the elapsed time measured by the time measuring unit reaches the predefined time period, the interrupt request supply unit supplies the interrupt request information to the processing unit.

    • The printer includes a CPU, a bridge image processing unit, a RAM, a ROM, a supply power control unit, a printing unit, a communication I/F, and physical layer I/Fs. When the Ethernet is connected to the communication I/F, if the DMA transfer request signal is not outputted from the DMAC for more than a specific time, the supply power control unit shifts into the sleep mode that halts the supplies of clock to the CPU, etc.; and if data is received from the host computer group, the supply power control unit releases the sleep mode. Further, in case that equipment conforming to the USB standard or the IEEE 1284 is connected to the communication I/F, if the DMA transfer request signal is not outputted from the DMAC for more than the specific time, the supply power control unit shifts into the power halt mode that halts the supply of power to the CPU, etc. Thus, the invention provides a printer capable of effectively reducing the power consumption.
