<P>PROBLEM TO BE SOLVED: To provide a printing system enhanced in an energy saving effect by suppressing occurrence of waiting time for restoration from a timeout by setting a long timeout period in the daytime and quickly shifting operation to an energy saving mode by setting a short timeout period in the nighttime without impairing convenience to a user. <P>SOLUTION: The printing system includes a printer having a plurality of operation modes, such as, for example, a standby mode and the power saving mode and capable of controlling the timeout period until transferring from the standby mode to the power saving mode from a computer, and a calculating unit connected to this. The calculating unit has a time counting means, a time length determining means and a transmitting means. The printer has a mode control means and a time information processing means. For example, the printer can be operated at different timeout periods in the daytime and nighttime. The printer can be operated at different timeout period according to the day of the week or date. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
