A printer includes a print head and a controller. The controller is configured to, using first print data containing a plurality of layers, select at least one, but not all, of the plurality of layers based on weight information regarding respective weights of the plurality of layers, generate second print data based on the selected at least one but not all of the plurality of layers, and control the print head to print at least one patch image on a printing medium based on the generated second print data.

An image processing apparatus comprises a first storage and a second, a plurality of image processing units that perform image processing on pixel data of image data read from the first storage or the second storage, and a writing unit that writes the pixel data, processed by the plurality of image processing units, into the second storage. The plurality of image processing units include a directivity image processing unit that performs image processing on the image data in mutually different directions by reading and supplying to an image processing unit of the plurality of image processing units the pixel data written into the second storage. Target pixel data processed by the directivity image processing unit is written into the second storage in an order of arrangement which is different from the order of arrangement of pixels in the image data stored in the first storage.

A receipt printing apparatus comprises a printer including a processor and a printing unit that is capable of printing on a printing medium. A registration device is connected to the printer. The printer stores a control program that when implemented by the processor causes the printer to acquire transaction details from the registration device, to receive a selection of a first output receipt type and a second output receipt type, and to output the transaction details in the selected one of the first output receipt type and the second output receipt type.

In a printer, when a storage print job is a print job for execution of carbon-copy printing, a controller performs: creating a plurality of bit map data by rasterizing page-description-language data contained in the storage print job a plurality of times; storing the created bit map data; and controlling an image former to print images based on the stored bit map data when a print instruction for the storage print job is received. When the storage print job is a print job not for execution of the carbon-copy printing, the controller performs: storing the page-description-language data contained in the storage print job; when the print instruction for the storage print job is received, rasterizing the stored page-description-language data to create bit map data; and controlling the image former to print an image based on the created bit map data.

In a printing device a computer creates raster data based on an image file. When creating the raster data, the computer selects a target object in the image file and performs selected one of first, second, and third processes. The first process is to store a set of extraction data. The second process is performed when the target object includes content data. The second process is to create a set of intermediate data based on the target object. The third process is performed when the target object includes data on a reference to another object. The third process is to store a set of extraction data from the another object. The raster data is created by performing a drawing process on one or more sets of created intermediate data. The computer increases an amount of available space of the memory by deleting one or more sets of extraction data.

In some examples, an imaging device can include a processing resource and a memory resource storing instructions to cause the processing resource to receive an operating parameter corresponding to a business model, configure the imaging device based on the received operating parameter corresponding to the business model, and operate the imaging device according to the received operating parameter.

An information processing device includes an information acquisition unit that acquires at least one of attribute information of image data to be image processed and setting information related to the image process on the image data, and a prediction unit that predicts, based on a machine-learned model that accepts input of at least one of the attribute information and the setting information to output a period required for the image process, a period required for the image process on the image data from information acquired by the information acquisition unit.

An image processing apparatus includes a reception unit configured to receive PDL data, an intermediate data generation unit configured to generate intermediate data on a basis of the received PDL data, a determination unit configured to determine units of generation for the intermediate data, and a transmission unit configured to transmit the intermediate data to a raster image generation unit configured to generate a raster image from the intermediate data each time the intermediate data is generated. The intermediate data includes edge information and filling information corresponding to an area surrounded by respective edges. The determination unit determines units of generation for the edge information and units of generation for the filling information. When the intermediate data generated by the generation unit is large, the units for the generation of the filling information are set to be larger than the units for the generation of the intermediate data.

A printer includes a print head and a controller. The controller is configured to, using first print data containing a plurality of layers, select at least one, but not all, of the plurality of layers based on weight information regarding respective weights of the plurality of layers, generate second print data based on the selected at least one but not all of the plurality of layers, and control the print head to print at least one patch image on a printing medium based on the generated second print data.

An image forming apparatus analyzes image data corresponding to a received job, and when as a result of the analysis is that the image data has a resolution that exceeds a predetermined value, determines a size of a sheet to be printed, and when a result of the determination is that the size of the sheet is a predetermined size, if a size of the image data is less than or equal to a threshold, stores image data to which halftoning processing is not performed in a memory, and if the size of the image data exceeds the threshold, stores image data to which the halftoning processing is performed in the memory, and based on a direction of the sheet, performs image forming on the sheet after performing rotation processing for the stored image data.
