Abstract:
A printing system having a printer which enters a sleep mode when it does not receive print data for more than a sleep time which is defined as a time from completion of printing to entry in the sleep mode, the system comprising:means for storing and controlling a standby time value for a corresponding printing operation of a plurality of printing operations, the standby time being a period between a start time of a present printing operation and an end time of a printing operation executed just before the present printing operation, the standby time being variable according to an operating condition of the printer; and means for calculating the sleep time based on standby time values stored in the standby time control means by putting weight on late values among the standby time values stored in standby time control means, wherein the sleep time calculated by the calculating means becomes shorter when the standby time becomes longer and the sleep time calculated by the calculating means becomes longer when the standby time becomes shorter and the standby time is equal to an actual sleep time plus sleep mode time.
