A printing device displays a preview image of received image data, receives, based on the previewed image, an instruction to rotate the received image, rotates the received image data based on the received rotation instruction, and prints the rotated image data.

A printing apparatus to communicate with a terminal apparatus, includes a storing unit, an acquiring unit, a receiving unit, and a printing unit. The storing unit stores information for specifying first paper types selectable in the terminal apparatus. The terminal apparatus acquires the information from the printing apparatus and displays the first paper types as selection candidate paper types. The acquiring unit acquires a second paper type. The receiving unit receives a first paper type from the first paper types for printing of an image. The printing unit prints the image where the first paper type corresponding to second paper types is received and any of the second paper types corresponding to the first paper type is acquired, and does not print the image where the first paper type corresponding to second paper types is received and another second paper type different from the second paper types is acquired.

An information processing apparatus receives a change of a parameter included in media characteristic information, causes, from media characteristic information held by a storage, the parameter for which the change is received to be held as custom media characteristic information, the apparatus performs an update of the media characteristic information held by the storage in accordance with new media characteristic information and decides, if an update of the custom media characteristic information is to be performed by using the new media characteristic information, whether to hold, or to update without holding, the parameter for which the change is received, based on a difference in configuration between the custom media characteristic information held by the storage and the new media characteristic information.

A printing device includes a printing head with nozzles, a movement mechanism that moves the printing head, and at least one processor. The processor controls the printing head to eject ink from each of the nozzles and to print on each position in a printing target area while causing the movement mechanism to move the printing head; and upon superposing printings in the printing target area based on pieces of data that are different from each other, controls the printing head to eject ink from at least one of the nozzles in each printing onto a different position from a position in a previous printing based on a different piece of data among the pieces of data for each of the superposing printings. The pieces of data is used in specifying from which of the nozzles ink is ejected onto each position in a printable area of the printing device.

A distribution portion that distributes an error based on quantization of a gradation value corresponding to the one pixel, to a first pixel located in a first direction of the one pixel at a first distribution rate, to a second pixel located in a second direction of the one pixel at a second distribution rate, and to a third pixel located in a third direction of the one pixel at a third distribution rate, the second direction is a direction that intersects the first direction, and the third direction is a direction different from an extension direction of a plane defined by the first direction and the second direction.

A printer includes: a memory configured to store a machine-learned model obtained by machine learning using teaching data associating at least one of reflectance of a print medium, transmittance of the print medium, and image data obtained by capturing an image of a surface of the print medium with a type of the print medium; and a print controller configured to determine a type of a print medium using at least one of reflectance of the print medium, transmittance of the print medium, and image data obtained by capturing an image of a surface of the print medium and the machine-learned model.

An image forming device comprising a processing section processing a provisionally combined datum into which a part image datum and a pattern datum included in marking data are merged, the part image datum being prepared by arranging picture pattern data into a shape of the picture pattern data for each of parts, the processing section including a margin setting section setting a margin on a periphery of the part and an image processing section arranging an image prepared based on the part image datum in an area of the margin.

An identification apparatus uses a sensor to sense a sheet, thereby obtaining a parameter concerning a characteristic of the sheet, and identifies a type of the sheet based on a result of inputting the parameter obtained by the sensor to an estimation model obtained by machine learning using a parameter of a sheet as input data and a type of a sheet as supervised data, the type used as supervised data corresponding to the parameter used as input data. The apparatus performs re-learning such that the identified type of the sheet based on a result of inputting the parameter obtained by the sensor as the input data to the estimation model becomes the type of the sheet represented by input information if the identified type of the sheet and the type of the sheet represented by the input information are different.

An image forming apparatus includes an image bearing member; a transfer member; and a controller configured to execute a plurality of modes of outputting a test chart, the modes involving transferring a plurality of test images to the test chart by applying a plurality of different voltages to the transfer member. The modes include a first mode and a second mode, the first mode being a mode in which a number of voltage levels to be applied to the transfer member when the plurality of test images are transferred to the test chart is a first predetermined number, and the second mode being a mode in which the number of voltage levels to be applied to the transfer member when the plurality of test images are transferred to the test chart is a second predetermined number which is greater than the first predetermined number.

An image forming apparatus includes a reader configured to read a paper used for printing, a controller configured to generate paper information indicating the type of paper read by the reader, and a storage unit configured to store the paper information in association with history information of a paper. The controller updates history information corresponding to target paper information when the target paper information indicating a same type of paper as the paper indicated by newly generated paper information is stored, and causes the storage unit to store the newly generated paper information when the target paper information is not stored. The controller searches for paper information indicating the type of paper input in a search operation, and causes an operation panel to display the history information corresponding to the found paper information.
