Abstract: When executing an image forming process for same sheets divisionally a plurality of number of times, a subsequent image forming process needs to be prevented from becoming impossible depending on the process result of a preceding image forming process. To accomplish this, when executing a second image forming process for a sheet having an image formed by a first image forming process is designated, an image forming apparatus of this invention restricts execution of post-processing for the sheet that has undergone the first image forming process even when executing the post-processing for the sheet is designated.

Abstract: A printing control apparatus that causes printing by a printing unit having a fixing unit that fixes a recording agent on a sheet, the printing control apparatus including: a printing control unit configured to cause the printing unit to stop printing of a currently printing job, and print another job in a state that printing of the job has been stopped; and a determining unit configured to determine whether or not to permit execution of the other job in a state that the currently printing job has been stopped by the printing control unit, based on a fixing unit temperature necessary for printing of the currently printing job and a fixing unit temperature necessary for execution of the other job.

Abstract: To suppress a drop in printing productivity due to opening of a sheet storage unit in a group by a user instruction while printing is performed by switching two or more sheet storage units registered as the group.

Abstract: Another code image may be added so that a code image previously embedded in an original document image can be read. An image forming device may be configured to use, when a second code image is combined with the original document image including a first code image, a result of decoding of the first code image to generate a third code image; and also configured to combine the second code image with the original document image and combine the third code image on the second code image.

Abstract: An apparatus includes a printing unit configured to perform printing by a short edge feed mode or a long edge feed mode, an inputting unit configured to input a print job, a setting unit configured to set an upper-limit value of a number of sheets to be used for a job, and a control unit configured to control the printing unit to perform printing by the short edge feed mode if the number of sheets to be used for the print job is less than the upper-limit value, and to perform printing by the long edge feed mode if the number of sheets to be used for the print job is equal to or greater than the upper-limit value.

An image forming device includes: a generation means configured to use, when a second code image is combined with the original document image including a first code image, a result of decoding of the first code image to generate a third code image; and means configured to combine the second code image with the original document image and combine the third code image on the second code image.
