For a plurality of kinds of printing media, spectral information is produced from results of printing of at least five points in paper white of the printing media, black, and three primary colors of coloring and printing materials, and a learned model is generated in advance by machine learning that uses the spectral information as learning data. An identification section that identifies the kinds of the printing media by using the learned model is provided. The kinds of the printing media are identified by applying the spectral information produced from the results of printing of at least five points on a printing target medium on which printing is to be performed to the learned model, and the printing target medium is processed in accordance with the identified kind of the printing target medium. In the case of a new unlearned printing medium, transfer learning is performed to learn the printing medium, and the model is updated.

A printing apparatus has a sheet holding unit having a detection unit for detecting a size of a sheet which is held and a storage unit configured to store sheet information including at least a size of a sheet as information representing a sheet. The apparatus sets first sheet information selected by a user in association with the sheet holding unit from a plurality of items of sheet information stored in the storage unit and notifies the user of a mismatch in a case where a size of a sheet that the first sheet information set in the setting indicates, and a size of a sheet detected by the detection unit are mismatched.

An image forming apparatus includes a roller, a heater configured to heat the roller, an endless belt, a nip forming member, a supply roller configured to supply a sheet, and a controller. The sheet is nipped between the endless belt and the roller. The endless belt is nipped between the nip forming member and the roller such that a nip portion is formed. The controller is configured to supply a plurality of first kind of sheets by the supply roller at a first interval when the plurality of first kind of sheets are sequentially conveyed and supply a plurality of second kind of sheets by the supply roller at a second interval greater than the first interval when the plurality of second kind of sheets belonging to a kind in which curl occurs more frequently than the plurality of first kind of sheets are sequentially conveyed.

An object of the present disclosure is to perform printing such that partition work of an operator is reduced. One embodiment of the present embodiment provides a printing apparatus that prints images on a roll paper based on one or a plurality of jobs, the printing apparatus including: an image forming unit that forms one or a plurality of image sets, each formed of a partition page image and a content image, on the roll paper based on a job in which partition information for inserting a partition page is set; and a control unit that controls image formation by the image forming unit, in which the control unit controls the image formation by the image forming unit based on a remaining amount of the roll paper such that there is no interruption in the middle of the image set.

A consumable characteristic identification method is provided. The method comprises the following steps: detecting a consumable package (210); identifying a characteristic about a consumable associated with the consumable package (215); modifying a device setting according to the identified characteristic (220); and appending a log entry associated with the consumable package to a user activity log (225). A consumable characteristic identification apparatus and no-transitory machine-readable storage medium are also provided.

An information processing apparatus performs acquiring measurement results obtained by measuring a characteristic of a recording medium a plurality of times; inputting information corresponding to a type of the recording medium; acquiring an extraction range of the type indicated by the information, among extraction ranges set to respective types of recording media for determination of a type; setting, based on the measurement results and the type, a parameter for correcting the measurement results to reduce difference between the measurement results and the extraction range; correcting, by using the parameter, measurement results obtained by measuring a characteristic of a recording medium to be recorded; and extracting a candidate type of the recording media, the measurement results, based on the corrected measurement results and the extraction range.

A printer includes: a printing section; a transport belt that transports a print medium; a camera that detects both end portions in an intersecting direction that intersects a transport direction of the print medium among end portions of the print medium placed on the transport belt; and a control section that causes the printing section to execute printing based on print data while one end portion of the both end portions detected by the camera is set as a print start position and a distance from the one end portion to the other end portion is set as a width of the print medium.

An information processing device includes an acquisition unit acquiring image data and ink data, the image data being obtained by digitizing, as an image, the fabric before the printing process is performed, the ink data indicating a type of the ink, a storage unit storing derivation data for deriving a recommended parameter for at least one of the pre-processing device and the post-processing device, and a control unit deriving, based on the derivation data, the recommended parameter from the image data and the ink data, wherein the derivation data includes first data and second data, the first data being configured to define a learned model learned by machine learning, the learned model being configured to, when the image data is input, output fabric data indicating a feature value of the fabric, the second data indicating a correspondence relationship between the fabric data and the ink data, and the recommended parameter.

An image forming apparatus includes: a contact portion that is disposed at a position. where the contact portion is contactable with a recording medium; a cooler that cools the recording medium; and a hardware processor that controls a cooling action of the cooler on the recording medium based on information on a temperature of the recording medium.

An image forming apparatus includes: an image forming unit configured to form an image on a sheet of perforated paper which has been perforated; an input unit configured to receive first information and second information; and a processor configured to display an alarm display without performing sheet-passing of the sheet of perforated paper. The first information is information concerning the sheet of perforated paper on which an image is to be formed by the image forming unit and wherein the second information is information concerning whether to perform automatic double-sided printing on the sheet of perforated paper or not. The processor is configured to display the alarm display in a case where the automatic double-sided printing is instructed and it is determined that the sheet of perforated paper has a cut-off portion.
