Abstract
Code data is converted to an intermediate code data, the intermediate code data is stored in an intermediate code buffer memory, the intermediate code data is converted to picture element data, the picture element data is stored in a page buffer memory and the picture element data is transmitted to a page printer. After the code data is stored in the intermediate code buffer memory, control code data indicating one page part finishing is received in the intermediate code buffer memory buffer, and the printing process preparation signal is outputted to the page printer. When code data is converted to intermediate code data, a format of the code data is judged, to determine whether a conversion processing from the intermediate code data to the picture element data, corresponding to the code data, requires a processing time which extends beyond a predetermined time limit and if such is true the intermediate code data corresponding to the code data is immediately converted to picture element data and stored in the page buffer memory. A high speed processing time can be obtained. A lifetime decrease in the page printer can be restrained effectively. An improved image output system having a high accuracy and a high reliability can be obtained.
