An example image forming apparatus includes a print engine to form an image by using toners of different colors, a memory to store toner quantity information of the different colors of toners, and a processor to perform a print job by reducing a use of a toner with a small toner residual quantity ratio when a difference in a residual quantity ratio of the toner for each color is greater than or equal to a determined value on the basis of the stored toner quantity information.

An example method comprises identifying a plurality of supply levels corresponding to a set of print supplies of a print device. The example method further comprises coordinating depletion of the set of print supplies by selecting between black print and process black print for a print job of the print device based on the plurality of supply levels.

An information processing system includes an information processing apparatus that obtains a state of a job input to a printing apparatus, generates, based on the state of the obtained job, notification information including instruction information used to control the job, and transmits the generated notification information to a network. A mobile terminal apparatus receives the notification information from the network, and notifies, based on the received notification information, the instruction information used to control the job. The information processing apparatus also estimates an execution result of a job which has been input to the printing apparatus but is in an execution standby state, obtains, as a state of the job, the estimated execution result, and in a case in which the estimated execution result indicates abnormal completion, generates the notification information including the instruction information used to control the job.

A printing apparatus of the present invention receives a print job from an information processing apparatus and performs printing. The printing apparatus obtains, from the information processing apparatus, information indicating the number of pages per copy of the print job, determines whether double-sided printing is to be performed for the print job, and determines, based on the obtained information, whether the print job is a print job in which the number of pages per copy is an odd number of pages. The printing apparatus controls to print by inserting a blank page before a page that is received first in the print job, based on a determination that, in the print job, the number of pages per copy is an odd number of pages.

A method, apparatus, and non-transitory computer-readable storage medium for altering a digital image for a printing job, the method comprising receiving a requested printing job including the digital image, performing a segmentation on the digital image, extracting values of properties for a segment of the segmented digital image, determining, based on the extracted values of the properties for the segment, whether the segment of the digital image should be altered, and altering the segment of the digital image when it is determined the segment of the digital image should be altered, a resulting altered digital image being transmitted to a printer for printing.

A can body printing system includes: a host device 10; and a printing device 30 configured to print an image acquired from the host device 10 onto can bodies. The print image information acquisition section 301 of the printing device 30 acquires, from the host device 10, image information to which an authorization for printing on can bodies is added. The activation control section 305 of the printing device 30 prints an image based on the image information onto can bodies on the basis of the authorization for printing on can bodies added to the acquired image information.

An image forming apparatus includes a feeding unit, an image forming unit, a reading unit, a conveyance unit, a first discharge unit and a second discharge unit, a determination unit, and a control unit. When an (n)th sheet in a first copy is an abnormal sheet, remaining sheets include sheets fed by the feeding unit after the abnormal sheet is fed by the feeding unit until the image on the abnormal sheet is read by the reading unit, and the remaining sheets include a first group of remaining sheets and a second group of remaining sheets. The control unit is configured to execute an abnormal discharge mode in which the sheets of the first group of the remaining sheets are discharged to the second discharge unit and each of the sheets of the second group of the remaining sheets is discharged selectively to the first or the second discharge unit.

A printing system includes an acquirer, a comparator, a calculator, and an allocator. The acquirer acquires the number of media printed by a first printing device installed at a first location. The comparator compares the number of printed media acquired by the acquirer with the number of media specified based on a billing amount. The calculator calculates a first number of printable media of the first printing device based on the comparison by the comparator. The allocator allocates at least a part of the first number of printable media calculated by the calculator as a second number of printable media to a second printing device installed at a second location. The second printing device can perform printing as a billing target based on the second number of printable media.

An image forming apparatus according to the present disclosure includes: a hardware processor configured to control an image former on a basis of a job pertaining to a printing execution command. The hardware processor is configured to divide the job pertaining to the printing execution command into a plurality of shortjobs, and configured to stop conveyance of the roll sheet and forcibly eject degraded toner from a developing device of the image former at a pause timing between short jobs temporally adjacent to each other among the plurality of short jobs; and the hardware processor sets a job content of each of the plurality of short jobs such that an image of a printing target is inverted upside down for each job switching of the plurality of short jobs.

A set of computer-readable instructions, when executed by a computer in an information processing device, causes the information processing device to perform: a setting process; and in response to receiving a print instruction in which a cut print setting is set: a generation process; and a transmission process. The setting process sets the cut print setting for printing an image on a sheet and dividing the printed sheet at a center position thereof. The generation process acquires image data representing a target image to generate processed image data representing a processed image in which a gap area is arranged within a range including the center position. No colorant is deposited in a region on a sheet corresponding to the gap area during the printer printing the processed image on the sheet. The transmission process transmits print data based on the processed image data and a cut command to the printer.
