The present invention includes an offset processing section that performs offset processing for shifting a sheet to be outputted in a sheet width direction, a banner output section that prints a job attribute of a print job on a sheet, a job attribute determination section that determines the job attribute of the print job, and a control section that sets offset processing or banner output in the unit of a job attribute or in the unit of a job. When a job attribute of a preceding print job and a job attribute of a subsequent print job are different, offset processing and banner output are executed. When the job attribute of the preceding print job and the job attribute of the subsequent print job are the same, any one of offset processing and banner output is executed. Thereby, printed sheets can be easily obtained in the unit of a job attribute such as in the unit of a user.
