ABSTRACT:
A communication apparatus includes an ink jet type printer capable of shifting from a normal operation mode to a low power consumption mode in a stand-by state by rendering the printer to a sleep mode. A recovery level of the printer at the time of wakeup from the sleep mode is based on an elapsed time that is counted from a previous recovery execution time, and a recovery operation is based on the determined recovery level. In another aspect, in the power saving mode, a printer processing unit is not enabled, but then is enabled in reply to a change from the power saving mode to the normal mode, and a communication processing unit transfers control data to the printer processing unit in response to the change from the power saving mode to the normal mode to be used for controlling the printer unit.
