In a printing system capable of supplying a sheet of a job having undergone print processing by the printing unit of a printing apparatus to a post-processing unit capable of executing at least a specific type of post-processing among a plurality of types of post-processes, when the target job requires the specific type of post-processing, the printing apparatus is inhibited from executing print processing of the job without explicitly determining a sheet necessary for the print processing of the job by a user using a user interface unit. When the target job does not require the specific type of post-processing, the printing apparatus is permitted to execute print processing of the job without explicitly determining a sheet necessary for the print processing of the job by the user using the user interface unit.

A job management server, which is connected to a Web application server and a job processing apparatus via a network, comprises: a registration unit which registers, when a job received from the Web application server is added with information indicating that a request source of the job is the job processing apparatus, the job in a first job queue, and to register, when the job is not added with the information, the job in a second job queue having a lower priority than the first job queue; and a transmission unit which transmits the job registered in the first job queue in response to a request from the job processing apparatus while a user utilizes a Web application via the job processing apparatus.

A print data generating device is configured to generate print data for creating a printed medium by printing a target image on a heat-sensitive medium with a printing device. The printing device includes a thermal head having a heating element. The heat-sensitive medium includes: a base material; and a heat-sensitive layer. The base material has a transparency. The heat-sensitive layer is provided over one surface of the base material and is configured to develop a first color when heated to a first temperature or higher. The printing device is configured to control the heating element according to the print data to heat the heat-sensitive medium. The print data generating device includes a controller. The controller is configured to perform: (a) determining a condition of a background area on which the heat-sensitive medium is to be superimposed; and (b) generating the print data in accordance with the condition determined in (a).

An information processing device includes a table data acquirer that acquires table data; a print data generator that generates print data including an unconverted image in which information stored in the table data is not converted into other information when a user selects a text option and that generates the print data including a first code image obtained by converting the information stored in the table data into a one-dimensional code image when the user selects a one-dimensional code option; and a display controller that displays, on a touch panel, a fourth operation screen including an option region in which a plurality of options including the text option and the one-dimensional code option are displayed and a second table data region in which the table data is displayed.

An inspection apparatus for detecting a difference between image data obtained by reading a sheet, and a reference image of the image data. The inspection apparatus obtains first image data by reading a sheet having a patch image printed thereon, obtains second image data from print data of the patch image, performs edge correction on a line included in the second image data by applying an edge correction parameter, and obtains an edge correction parameter that minimizes a difference between the density of the second image data subjected to the edge correction and the density of the first image data, and stores the obtained edge correction parameter.

A method and system for producing a plant-based image includes receiving a source image; screening the source image into a set of picture elements; and producing raster data indicating at least a type or density of seeds or plants to plant for each picture element.

A first set correction target value set for a correction target value generation region including a unit region corresponding to one or more nozzles is updated based on a difference between the first set correction target value and a print density in the unit region corresponding to the correction target value generation region. Also, a second set correction target value set for a correction target value generation region being adjacent to an updated region which is a correction target value generation region updated in the correction target value and having yet to be updated in the correction target value is updated based on a difference between the second set correction target value and the correction target value of the updated region.

An image forming system includes an image forming apparatus and a terminal device. The terminal device converts a document into first print data, generates a second hash value corresponding to second object data in first print data, generates second print data, when the second hash value accords with the first hash value in a first storage device, by substituting the second object data in the first print data with the first hash value, and transmits the second print data to the image forming apparatus. The image forming apparatus substitutes, upon receipt of the second print data, the first hash value included in the second print data with the first object data corresponding to the first hash value and stored in the second storage device, generates second bitmap data by analyzing the second print data subjected to the substitution, and causes an image forming device to execute a printing operation.

A print management unit attaches an identifier to print data that goes through a custom processing unit functioning by execution of a custom class driver, and delivers the print data with the identifier attached, to a standard print control unit. The custom processing unit deletes the identifier from the print data delivered from the standard print control unit and customizes processing of causing a printer to execute printing, based on the print data. The print management unit detects a read state of the custom class driver by execution of an OS. When the read state indicates a failure in reading the custom class driver, the print management unit delivers the print data without the identifier attached, to the standard print control unit, and thus causes the printer to execute the printing that is limited via a standard communication control unit or to stop the printing.

An image forming device includes: an image forming unit that forms an image on a transfer medium; and a controller that controls multiple image readers capable of performing image reading for the same surface of the transfer medium, and acquires reading results from the image readers. The controller is capable of performing failure/no-failure determination for the image on the transfer medium based on the reading results, of switching image reading by the multiple image readers between reading by a first number of image readers and reading by a second number of image readers, the second number being smaller than the first number, and of enabling, while the second number of image readers perform reading, at least one of the other image readers to execute a maintenance operation for the at least one of the other image readers.
