PROBLEM TO BE SOLVED: To prevent unconformity from occurring as a print document by inhibiting the change of the setting of paper size on another job setting picture at the time of executing a job requiring paper feeding from a paper feeding stage such as a manual feeding tray. SOLUTION: Whether the job A (printing job) is being executed is judged (S1002). In the case of judging that the job A is being executed, respective keys are set to halftone displayed in order to inhibit the change of the setting (S1003). Whether a job B different from the job A corresponding to the setting picture displayed on a display panel at present is being executed is judged (S1006). In the case of judging that the job B is being executed, whether the job B is fed from the manual feeding tray is judged (S1007). In the case of judging that the job B is the one using the manual feeding tray, a manual feeding tray key on a paper selection screen is set to halftone displayed so as to inhibit the change of the setting (S1008). |
