A print processing device comprises: a storage to store an input print job including image data of plural pages; a print processor to perform printing to plural papers based on the image data of the plural pages; an image reader to acquire the image data for each page of the plural printed papers; a determiner to determine whether a print state for each page is good or bad, by comparing the acquired image data for each page with stored corresponding image data; and a controller to control, if the print state for a specific page is bad, the print processor to perform reprinting based on the image data of the specific page and the image reader to stand by for reading of a subsequent page until the reprinting ends, thereby enabling to easily replace, in the reprinting for a page of bad printstate, this page with the reprinted page.
