Filed: 1994-03-31
Abstract: PURPOSE:To set a suitable time interval for the operating environment of a recording device by updating the time interval set for shift to the power saving control based on the interval set for receiving data from an external device. CONSTITUTION:A print holding state is set when the reception of data from a host computer 1300, the print processing of the data and a panel operation given to an operation pattern 1200 are all finished. At the same time, a time counter C included in a RAM 1108 is initialized. Then the print holding state shifts to a sleep state when the coincidence is secured between the value of the counter C and two values of an NVRAM 1106. The present value of the counter C is written in the NVRAM 106 as a time interval D' to the next sleep state when a job is continuously carried out. When a sleep shift holding state is canceled, the interval D' is written in the NVRAM 1106 as the set value D. Thus the time needed for shift to the sleep state is automatically updated according to the access frequency to a printer in a system. Then the power saving can be effectively controlled.
