Abstract: An image forming apparatus includes a memory and a warning unit. The memory stores information indicating a past document that has been processed for printing in the past and a past print setting that is a print setting used when the past document has been processed for printing in association with each other. The warning unit outputs a warning to a user in a case where a present document that is presently processed for printing is identical or similar to the past document, and a present print setting that is a print setting set for the present document is different from the past print setting for the past document.

Abstract: A page layout control device having a receiving unit that receives booklet designation information for printing two pages on each of both sides of a recording sheet and saddle-stitching as printing information for printing on a single recording sheet; a booklet page layout processing unit that carries out page layout processing in which two pages are laid out on each of both sides of each recording sheet such that pages are collated after a booklet is created, and a trial page layout processing unit that, when printing side information for designating a printing side of the recording sheet in the booklet designation information received by the receiving unit indicates single-sided printing, carries out page layout processing.

Abstract: An image information acquisition unit obtains first print image information that is binarized with the use of a first threshold matrix. A threshold matrix information acquisition unit obtains information representing the first threshold matrix. A determining unit divides the first print image information obtained by the image information acquisition unit into a plurality of portions, and determines whether each of the divided portions includes contour information, based on the first threshold matrix obtained by the threshold matrix information acquisition unit. A generating unit generates second print image information by performing a re-binarizing operation for each of the divided portions of the first print image information with the use of a second threshold matrix that is different from the first threshold matrix, based on the determination result of the determining unit.
