A roll paper supply device rolls out roll paper and cuts the rolled-out portion of the roll paper to produce a first sheet. A control device determines, for each print process, whether or not the roll paper supply device is in a specific state in which the roll paper supply device has conveyed the first sheet to a specific position. When it is determined that the roll paper supply device is in the specific state, the control device causes the roll paper supply device to execute a process of conveying the first sheet to a print position. When it is determined that the roll paper supply device is not in the specific state, the control device causes a cut sheet supply device to execute a process of conveying a second sheet to the print position.

A title reliability calculator calculates a title reliability level of each character area using a feature quantity data set and a machine learning model. A character recognizer converts character areas of which title reliability levels exceed a threshold into text data. A title judger collates text data with a title candidate. In a case in which one piece of text data coinciding with a title candidate is judged and detected, the title judger sets the text data as a title of the document image. In a case in which a plurality of pieces of coinciding text data are judged and detected, the title judger sets text data of which a title reliability level is the highest among the detected pieces of text data as a title of the document image.
