A print control apparatus includes a storage unit, a reception unit, a change unit to change sheet information, and an instruction unit and communicates with a printing apparatus. The printing apparatus has a plurality of sheet holding units to hold sheets that can be conveyed and used for printing. The storage unit stores sheet information of the sheets held in a different one of the plurality of sheet holding units. The reception unit receives sheet information of a sheet held in a sheet holding unit of the plurality of sheet holding units. If the stored sheet information of the sheet held in the selected sheet holding unit is changed to the received sheet information, the instruction unit instructs the printing apparatus not to use the sheet held in the selected sheet holding unit for printing.

Apparatus and method disclosed herein are used in a production facility including an inventory of base substrates and laminates used in the production of graphics, the production facility further including at least one printer and at least one laminating machine. Base substrates, such as adhesive backed vinyl films, and laminates are received at the facility and labeled to be identified in a production process. Project data stored in a data storage system, and data concerning the substrates and laminates, is used by a production control system to control the process of printing graphic images on the substrate, and laminate the substrate.

An information processing device includes a retaining unit and an image display. The retaining unit retains image-formation-related information of an image forming apparatus that forms an image. The image display causes a display section of a portable terminal having the display section and an image capturing section to display an image for assisting with an operation of the image forming apparatus based on a captured image result of the image capturing section and the image-formation-related information retained in the retaining unit.

A roll-fed printing apparatus for printing at least a first and a second image on a recording medium, a method for controlling such a printing apparatus and a software medium are disclosed. According to the method, each swath is printed by a print head that reciprocates in a scanning direction, the print head being controlled to apply marking material to the recording medium in accordance with a first set of image lines for each swath to be printed; the first set of image lines being provided to the print head from a swath buffer; wherein the first set of image lines are transmitted to the swath buffer out of a second set of image lines stored in a line buffer to be printed without interruption; wherein, when the line buffer comprises the final image lines of a first bitmap representing the first image while there are still empty data storage sections within the line buffer starting image lines of a second bitmap representing the second image are transferred to the empty data storage section of the line buffer.

An image processing apparatus for a printing apparatus. The image processing apparatus includes a recording position acquiring device for acquiring recording positions of a reference image printed by a reference print head and a target image printed by a target print head, a positional deviation amount calculating device for calculating a deviation amount due to a skew with respect to the recording positions of the reference image and the target image, and a positional deviation interpolation image converting device, when there is a remainder of the deviation amount and the predetermined intervals, for adding a weight based on the remainder, and adding a smaller weight than the weight to the reference image or the target image without a remainder and adjoining the reference image or the target image with the remainder, thereby converting the image into a width direction positional deviation interpolation image.

A print preview of each page is correctly displayed even in the case of a print job including a plurality of pages requiring different sizes and types of print medium. For this purpose, print medium information about a print medium fed from each of a plurality of feeding units provided in a printing apparatus is acquired and, based on this information and setting information set for each of a plurality of pages included in a print job, each of the pages is allocated to a print medium fed from any one of the feeding units. After that, a preview in which a page allocated to a first print medium fed from a first feeding unit is laid out on an image representing the first print medium and a preview in which a page allocated to a second print medium fed from a second feeding unit is laid out on an image representing the second print medium are displayed.

An information processing device includes a retaining unit and an image display. The retaining unit retains image-formation-related information of an image forming apparatus that forms an image. The image display causes a display section of a portable terminal having the display section and an image capturing section to display an image for assisting with an operation of the image forming apparatus based on a captured image result of the image capturing section and the image-formation-related information retained in the retaining unit.

An image forming apparatus includes an operation acceptance section, a storage section, a sheet feed cassette, a plurality of trays, a sorting mechanism, a scanner, a data analyzing section, and a control section. The scanner scans an image of a sheet. The data analyzing section analyzes image data of the sheet scanned by the scanner. When the operation acceptance section accepts a specification of a sorting condition from a user, the control section allows the storage section to store the sorting condition and allows the sorting mechanism to sort the sheet to one of the trays according to the sorting condition using an analysis result of the data analyzing section.

Image stitching from multiple line scanners may be provided by selecting, at a plurality of times while progressing a film roll from a supply reel to a take-up reel, overlap areas on the film roll between first and second field of views of a first and second line scan sensors that read first and second data streams from the film roll; calculating, at each time, a difference measure between the first and second data streams in a current overlap area for a current time; adjusting, based on the difference measure, a size or a position of the overlap area for use at a subsequent time as the film roll progresses such that the current overlap area has a first number of pixels and a subsequent overlap area has a second number of pixels; and blending the first and second data streams at the current time at the current overlap area.

Upon receiving an occupation request command from an information processing apparatus, a control device performs an occupation control to set a specified supply portion as an occupied supply portion from when an occupation establishment event occurs to when an occupation release event occurs. When a multiple use request state occurs by receiving, from other information processing apparatuses, the 2.sup.nd and onward occupation request commands that specify the occupied supply portion as specified supply portions, and after the occupation control ends, the control device executes the occupation control for each of the 2.sup.nd and onward occupation request commands in an order in which the 2.sup.nd and onward occupation request commands were received.
