<P>PROBLEM TO BE SOLVED: To provide a printer capable of taking a problem to be solved into consideration, capable of collecting a result of a printing situation in every time zone of a fixed time interval, capable of reducing an electric power consumption, based on the result, and capable of feeling hardly a waiting time for warming-up. <P>SOLUTION: This printer includes a storage means for storing an average value of printing frequency executed within the fixed time interval, by dividing one day by the fixed time interval, the first threshold value calculating means for calculating a maintaining time of a printable state requiring electric power in which electric power for maintaining the printable state exceeds electric power for maintaining an electric power saving state and for the warming-up to the printing state, and for calculating the printing frequency executable within the fixed time interval in the maintaining time of the printable state, as the first threshold value, and a control means for controlling the printable state to be maintained, when the average value of the printing frequency within the fixed time interval stored in the storage means is higher than the first threshold value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
