A print system includes an image processing apparatus and a print apparatus that receives a print job processed by the image processing apparatus and prints an image on a sheet. The print apparatus determines whether or not a print job received from the image processing apparatus is a measurement target for measuring an image printed on a sheet, measures the image on the sheet printed by executing a print job that has been determined to be the measurement target, and transmits the result of measurement to the image processing apparatus. The image processing apparatus generates a print job serving as a measurement target, and upon receiving the result of measurement based on the transmitted print job, applies the result of measurement to a print job to be printed by the print apparatus.

A printing apparatus includes a printing head to move in a first direction, a conveying roller to convey the printing medium in a second direction intersecting with the first direction, and a housing to house the printing head and the conveying roller and be expandable and contractible in the first direction. The printing apparatus performs predetermined notification based on information related to a length of the housing in the first direction, wherein the conveying roller is incapable of conveying the printing medium having a predetermined size when the length of the housing in the first direction is a first length and conveys the printing medium having the predetermined size in a case where the length is a second length larger than the first length. The predetermined notification is performed based on the information related to the length of the housing indicating information corresponding to the first length.

An image processing apparatus extracts a margin portion from an input image in a case in which the input image is a margined formation target image formed so as to include a margin, and automatically executes, based on the extracted margin portion, a print setting of the input image.

An apparatus configured to generate image data represented in achromatic color from input image data and output the generated image data to a printer includes a controller. The controller is configured to replace color information of an object included in the input image data with an achromatic signal value, determine, based on an achromatic signal value corresponding to color information of a pixel of interest in the input image data, whether the pixel of interest satisfies a predetermined condition, and perform enhancement processing on the color information of the pixel of interest in a case where the pixel of interest is determined not to satisfy the predetermined condition.

An image forming apparatus has an office direct print function, and when a non-installed font that is not installed in the image forming apparatus is included in application data, a font substitution guidance screen is displayed on a display. A drop-down list that is an operator for selecting a substitute font is provided in the font substitution guidance screen, whereby a user can arbitrarily select a substitute font. The font substitution guidance screen displays also a sample character group having a typeface according to the selected substitute font.

An image processing apparatus for converting color data into gray data extracts an object included in the color data in a page, and determines, based on color information and position information on a first object and a second object extracted, whether at least one of the first object and the second object is to be a target of conversion of a color value of the color data into a gray value with improved discriminability. The image processing apparatus controls to convert the color value of the object into a gray value by a conversion targeting all color values, or into a gray value with the improved discriminability, based on the determination whether or not to be the target of conversion.

In an example, a method comprises: for each of a plurality of areas of a target image, determining a color vector representing that area, wherein the color vector is defined in a color space. The method may further comprise producing a color histogram of the target image by associating each area of the target image with a histogram bin representing a particular color, based on the determined color vector of the area; defining a color represented by a histogram bin associated with a highest number of image areas as a dominant color of the target image; and applying a correction to a print version of the target image for an area that is intended to have the dominant color.

An image processing apparatus includes an acquisition unit configured to acquire an image captured by an imaging unit, and image capturing information at the time of image capturing of the image, and a calculation unit configured to calculate an object side pixel dimension of a target subject in the image based on the image capturing information and a pixel dimension of the imaging unit, wherein the acquisition unit acquires in-focus information indicating an in-focus state of a subject in an image, as the image capturing information, and wherein the calculation unit calculates the object side pixel dimension based on the in-focus information.

A measuring device includes a first roller pair, a colorimetric unit, a second roller pair, a third roller pair, a motor, and a torque limiter. The third roller pair is driven at a first speed before a trailing end of the sheet with respect to a sheet feeding direction passes through the first roller pair and is driven at a second speed higher than the first speed after the trailing end of the sheet passes through the first roller pair. The first speed is set so as to be equal to the peripheral speed of the first roller pair. The second speed is set so as to be equal to a peripheral speed of the second roller pair in a state in which a slip of the torque limiter is not caused.

An image forming system includes processing circuitry. The processing circuitry generates print image data for printing a first image in a print area on a conveyance medium. The processing circuitry controls printing on the conveyance medium based on the print image data. The processing circuitry determines a position at which a second image is printed in a cut area, based on a position of a cutting mark, to generate the print image data including the second image, the second image including identification information to identify each page of the conveyance medium, the cut area being an area to be cut in the print area.
