Abstract: PURPOSE: To record information while containing the information surely into one page of cut paper by calculating a reduction rate in the case of recording an image to be contained in one recording paper sheet based on a size of recording paper and a size of an image and reducing the output image depending on the reduction rate. CONSTITUTION: In the case of commanding an output of a report, a CPU 21 reads a total data line number DL at a head of output form data of a designated report from a ROM 22 and calculates a total recording paper line number PL available of being recorded on recording paper. Then based on the DL and PL, a reduction rate requiring to record a report on one recording paper sheet is calculated. In this case, the reduction rate is decided by taking a space to be provided at the surrounding of recording paper usually into account. Thus, when the reduction rate is calculated in this way, the recording section 2 is controlled depending on the reduction rate and an image is reduced and the reduced image is outputted. Thus, it is avoided that the outputted information is divided into plural pages and the user is easily able to observe the image output.
