  A feature image switching key 618 is an operation key for performing the switching operation. For example, when the feature image switching key 618 is operated by the user, the feature image displayed in the plurality of feature image display fields 613 is changed from the partial image of the page of the document corresponding to the character string indicating the chapter number. Switching to a partial image of the original page corresponding to the character string in the first line of each original page. As a result, the user can specify a page of the document by switching a plurality of the feature images. A plurality of the feature images may be displayed in combination in the feature image display field 613.

  A print execution key 619 is an operation key for instructing execution of print processing. When the print execution key 619 is operated, the control unit 5 determines that the designation operation by the user has been completed, and executes the process of step S8 of the print control process. That is, the user operation for the print execution key 619 is a user operation for ending the designation operation.

  As described above, in the print control process, the characteristic image of each page of the document is displayed on the operation display unit 6. Then, based on the feature image displayed on the operation display unit 6, the user can specify the page of the document that is the execution target of the specific process.
