When printing on the same printing object with multiple print nozzles in the past, consideration was not given to cases in which the time relationships of the set times and times-to-be-printed become mismatched between the respective print items of the print nozzles. To solve this problem, an inkjet printer that prints on a conveyed printing object and has multiple print nozzles, multiple auxiliary control units for controlling the printing performed by the multiple print nozzles, and a common main control unit connected to the multiple auxiliary control units via communication unit is provided. The main control unit extracts the time relationship of the set times and the time relationship of the times-to-be-printed between the items to be printed by the respective print nozzles of the multiple print nozzles and revises the print data so as to preserve the time relationship of the set times.

A printing system includes a printer and an information processing device that includes a processor and a memory storing processor-executable instructions, the instructions being configured to, when executed by the processor, cause the processor to, when there is not information stored in a queue area of the memory, determine to instruct the printer to start a pre-printing operation based on preparation instruction information. When there is information stored in the queue area, determine not to instruct the printer to start the pre-printing operation. In response to determining to instruct the printer to start the pre-printing operation, store the preparation instruction information into the queue area, and in response to determining to instruct the printer to start the pre-printing operation and storing the preparation instruction information into the queue area, generate print data based on specified contents data, and store print instruction information into the queue area.

When writing information to the IC tag of a medium, the control unit 54 of a printer 1 determines if a specific area in the storage space of the IC tag is in an initialized state, and writes to the IC tag if the IC tag is in the specific state.

A printing device tracks characteristics regarding duplex print jobs received and printed at the printing device. The print device adjusts the start time of a duplex print engine of the printing device following receipt of a new duplex print job at the printing device to print the new duplex print job, based on the tracked characteristics, to optimize a balance between print job performance and print engine wear.

An image forming apparatus includes an input section, an image forming section, and a controller. The input section inputs a command for executing printing on a sheet. The image forming section forms an image using a recording agent on the sheet based on the command input by the input section. The controller controls the image forming section to print a predetermined number of sheets among all pages subjected to the printing according to a printing command and executes the printing on the remaining pages after a predetermined continuation condition is satisfied if the printing command input by the input section corresponds to a specific printing condition.

An image forming apparatus stores raster image data corresponding to a background in a compressed format and generates intermediate data corresponding to a foreground of the background based on obtained print data. A decompressor decompresses the raster image data stored in the memory device and a rasterizer generates new raster image data based on the raster data corresponding to the background obtained by the decompression and the generated intermediate data corresponding to the foreground. When a request is made to stop the generation of the new raster image data in a state of waiting for at least a portion of the raster image data corresponding to the background to be decompressed, the rasterizer stops generation of the new raster image data, and the decompressor continues decompressing the at least a portion of the raster image data corresponding to the background.

An image forming apparatus includes a circuit configured to generate an image based on the PDL data, a generating unit configured to generate an image corresponding to at least part of a plurality of pages included in the PDL data, according to acquisition of the PDL data, a holding unit configured to hold the image generated by the generating unit into a storage, and an obtaining unit configured to obtain images of all pages to be printed among the pages included in the PDL data according to the print instruction from the user, wherein the obtaining unit instructs the circuit to skip image generation of a page of which an image is already generated by the generating unit among the pages to be printed, and instructs the circuit to perform image generation of a page of which an image is not generated by the unit configured to generate.

An object of the invention is to solve low productivity of foil-stamping printing due to frequent replacement of foil rolls when the positions of sizes of foil objects are different in a plurality of jobs. A grouping unit groups jobs on the basis of a foil roll which can be attached to a foil stamping device and foil object information. A job sorting unit sorts the grouped jobs on the basis of a sorting policy by group. A foil-stamping print data transmitting unit transmits foil-stamping print data including the foil object, which is extracted from print data to a foil stamping device. A foil roll replacement information output unit outputs foil roll replacement information indicating a timing that a foil roll is replaced.

The disclosure discloses a printer including a first memory that stores computer-executable instructions that cause the printer to perform a terminal searching process, a job receiving process, and a coordination control process. In the terminal searching process, it is searched whether any of the operation terminals retains the printing job conforming to an accepting condition or not, by performing the mutually-recognized communication triggered by reception of a signal of an action-starting operation in a starting operation accepting process. In the job receiving process, in the case that some of the operation terminals retain the printing job conforming to the accepting condition, the printing job from the operation terminal is received. In the coordination control process, the printing head and the feeder are controlled in coordination with each other in the manner that the printed matter in accordance with print data in the printing job is produced.

Provided is a method of processing a workflow that cannot be solely processed by an image forming apparatus, by using a resource of a mobile device in which a bring your own device (BYOD) application is installed, and a mobile device for performing the method.
