Abstract
When a pre-rotation sequence is started at a time at which a print-start notification command is transmitted, in the case where a predicted time period is longer than a time period taken to perform the pre-rotation sequence, an appropriate FPOT is not realized. To determine whether the pre-rotation sequence can be started at a time at which a print reservation command that is to be transmitted before transmission of the print-start notification command is transmitted to the engine, a drum-rotation permission command is provided, whereby, in the case of immediately starting the pre-rotation sequence, the pre-rotation sequence can be started earlier than the pre-rotation sequence is started, reducing the FPOT. In the case of not immediately starting the pre-rotation sequence, a time period taken to perform image expansion and the time period taken to perform the pre-rotation sequence can be made to coincide with each other, reducing consumable items deterioration.
