An image processing apparatus includes the following elements. An image information generator generates, in response to an instruction, print image information to print plural pieces of image information in parallel in plural columns. A division manager divides the print image information into regions, each region having a length equal to the greatest common divisor of lengths of the image information. A manager manages, every time a printing operation is performed, the regions subjected to the printing operation such that the regions are divided into print guaranteed regions and print non-guaranteed regions. A print restart region determining unit determines, upon detection of an occurrence of an abnormality during the printing operation, a print restart region after recovery from the abnormality is completed on the basis of the print guaranteed regions and the regions of the print image information.
