Disclosed is an image forming apparatus, which may execute a job including printing an image. The disclosed image forming apparatus may include: a printer; a detector that may detect a property of a printing paper sheet, the printing paper sheet being a paper sheet used by the printer in the printing; and a determinator that may, on the basis of the property detected by the detector and a situation of the job, determine conditions for executing the printing.

An object of the present disclosure is to enable a user to easily set a line width adjustment value in a case where line widths are matched between different printing apparatuses. One embodiment of the present invention is an information processing apparatus that performs processing for putting a width of a line in an output in a case where printing is performed by a first printing apparatus based on print data including a line close to a width of a line in an output in a case where printing is performed by a second printing apparatus based on the print data and has: a first acquisition unit configured to acquire first information relating to an output in a case where printed matter including a plurality of line width detection images is printed by the second printing apparatus.

An image forming system having a printing apparatus including a feeder to be pulled out and an image forming unit. The printing apparatus further includes a reception unit to receive a user instruction for setting sheet information on a sheet in association with the feeder. Based on set sheet information, the image forming unit forms an image on a sheet fed from the feeder. The image forming system further includes a display unit to display feeder information and a detection unit to detect that the feeder in a pulled-out state is closed. The display unit displays the feeder information subjected to the user instruction in a first display form and, based on a detection by the detection unit, changes the display by the display unit including the first display form having the feeder information to a display including a second display form different from the first display form.

An image forming apparatus includes a reading section and an image forming section. The reading section reads a plurality of images formed on a document. The image forming section forms the images on a plurality of sheets. The images include a first image having a first color, and one or more second images having a second color differing from the first color. The sheets include a first sheet and a second sheet differing from the first sheet. The image forming section forms the first image on the first sheet and the second images on the second sheet.

A print instructing device includes: a recording section that, in a case in which history information does not include size information indicating a size of a print medium designated by a print demand that demands an execution of printing, records paper quality information indicating a paper quality of the print medium designated by the print demand in association with the size information in the history information; and a display controlling section that, in a case in which the size information is included in the history information and the paper quality information does not match the history information corresponding to the size information, causes confirmation information confirming whether or not to change the designated paper quality to be displayed.

An optical scanning device includes a reflected-light passing unit having a passing region through which a portion of reflected light that is the scanning light reflected by the medium passes. An outer peripheral contour line of the passing region includes a contour curve configured with a set of points where coordinates in a direction orthogonal to a scanning direction are uniquely determined for the coordinates in the scanning direction. The contour curve renders a curve protruded toward the passing region. When a region in contact with the contour curve in the passing region is divided into a plurality of quadrilateral minute regions having equivalent areas and extending from the contour curve to a predetermined coordinate position in the scanning direction and are continuously arranged in the orthogonal direction, widths of the minute regions in the scanning direction are different for each location in the orthogonal direction.

An image forming apparatus including: a measurer which measures a physical property of a medium on which an image is formed; an image forming operator which forms the image on the medium; a reader which reads the formed image; and a hardware processor which specifics a medium type based on a measurement result by the measurer and a reading result by the reader.

A non-transitory computer readable medium storing computer readable instructions configured to, when executed by a processor of a computer, cause the processor to: receive preparation instruction information from an information processing terminal, in response to receiving the preparation instruction information, cause an operating unit to execute at least one pre-printing operation of which operation content accords with a particular execution condition indicated by particular condition information in the preparation instruction information, receive print instruction information from the information processing terminal, the print instruction information instructing execution of the printing operation according to an execution condition, in response to receiving the print instruction information, determine whether the at least one pre-printing operation has already been executed; and in response to determining that the at least one pre-printing operation has been executed, cause the operating unit to execute the printing operation indicated by the print instruction information.

An image forming apparatus includes: a plurality of output trays; a storage device that stores a table, each of the plurality of output trays and a combination of a plurality of attributes of sheets-allowed-to-be-output being registered in association with each other in the table; and a controller that receives a print request, the print request including a plurality of attributes of a sheet-to-be-printed, determines whether or not a combination of the plurality of attributes included in the print request is registered in the table, if determining that the combination is not registered in the table, selects an output tray as a tray-to-catch-output-sheet with reference to the table, at least one attribute included in the print request being registered in association with the output tray selected, and if determining that none of the plurality of attributes included in the print request is registered in the table, selects no tray-to-catch-output-sheet.

An image processing apparatus includes an scanner, a print engine, and a controller configured to control the scanner to scan images of one or more document sheets, thereby generating scanned image data, generate print data based on the scanned image data, control the print engine to print, on sheets, the images based on the print data, generate first log image data through reducing a data size of image data associated with the scanned image data, determine whether the first log image data includes a particular type of page, and when determining that the first log image data includes the particular type of page, generate second log image data having higher image quality than the first log image data.
