A printing system includes processing circuitry. The processing circuitry acquires print data of a plurality of pages and extracts comparison data from the print data for each page. The processing circuitry, from first image data read from a printed material on which the print data is printed, acquires second image data at a position corresponding to the comparison data, for each page of the printed material. The processing circuitry outputs a comparison result of the comparison data and the read image data for each page.

Printing system, image processing apparatus, and comparison method

An image forming apparatus is configured to arrange a plurality of pages, including a first page and a second page adjacent to the first page, in print data, without providing a margin between adjacent pages in the plurality of pages. The image forming apparatus includes a changer configured to change at least one of a position or an angle of the second page, such that a color of a first edge portion region of the first page and a color of a second edge portion region, adjacent to the first edge portion region, of the second page, satisfy a predetermined condition.

Systems and methods for arranging adjacent pages based on print data associated with the pages

An information processing apparatus includes a print management unit configured to allocate a plurality of print data sets to a plurality of image forming apparatuses, respectively, the plurality of print data sets being obtained by dividing one print data set; a separator data generation unit configured to generate, for each of the plurality of image forming apparatuses, print data for a separator, the print data for the separator including management information that includes information regarding a particular print data set among the plurality of print data sets and information regarding a particular image forming apparatus among the plurality of image forming apparatuses to which the particular print data set is allocated; and an output unit configured to output, for each of the plurality of image forming apparatuses, the particular print data set and the print data for the separator to the particular image forming apparatus.

Information processing apparatus, information processing system, information processing method, and storage medium

The invention provides a method for a portable electronic device such as a computer to be capable of safely coping with the occurrence of a surprise removal from an external hard disk drive (HDD) connected by wireless. An HDD is connected to a portable computer by wireless via a wireless extension device. First, a wireless communication path between the HDD and the portable computer is configured. Subsequently, a file is read and edited by accessing the HDD from the portable computer. Next, removal information indicating that the portable computer is away from the HDD is produced. The removal information can be produced by detecting an acceleration generated in the portable computer, or by directly detecting the distance by the strength of the wireless signal. Data under editing is saved before occurrence of surprise removal by ejecting the HDD in response to the production of the removal information.

Described is an illumination structure suitable for a keyboard light of a portable computer. An example illumination structure includes a transparent acrylic board, a light source, and a light guide. The acrylic board may have a front surface and a rear surface, each of which is flat. The light source is provided at a tilt angle q at which an optical axis is almost at a critical angle with respect to the rear surface of the acrylic board. The light guide is located between the light source and the rear surface. Further, light rays radiated from the light source are refracted by the light guide and the optically-transparent panel, and travel towards the front surface, so as to illuminate the surface.

Portable computer illumination

An I/O housing holds an I/O port and is pivotable between a housed position, wherein the I/O housing is held snugly flat in a chassis of the computer, and an extended position, wherein the port end of the housing is distanced from the chassis. The I/O housing can mechanically engage an I/O device with the port establishing communication between the I/O device and the computer processor.

Flippable I/O port for portable computer

A method for docking/undocking a portable computer to/from an expansion unit is disclosed. The portable computer includes a main battery, and the expansion unit includes a second battery. In response to an eject event, the condition of the second battery is determined. If the second battery is in a discharging condition, a power supply route is switched from the second battery of the expansion unit to the main battery of the portable computer. If the second battery is in a charging condition, the charging condition is suspended. At this point, a hot undocking of the portable computer from the expansion unit can be performed.

Method for docking/undocking a portable computer to/from an expansion unit

Described is an improved method for undocking a structure having an optional number of tiers from a multilayer-dock structure constituted by docking a plurality of expansion units respectively having an intrinsic resource to a portable PC. To undock only a portable PC from a triple-layer-dock structure constituted by docking a first expansion unit and a second expansion unit to the portable PC, the first expansion unit is made to generate an undock event. The IDE device of the first expansion unit and the PCI device of the second expansion unit are separated from the control by an operating system by taking the undock event as an opportunity and the interfaces of the devices and are electrically separated. The operability is improved because it is possible to unitedly obtain an object to be undocked through both vision and operation.

Described is a substrate connector assembly which includes a first circuit substrate, a second circuit substrate and a connector mounted on the first circuit substrate for connecting wiring patterns formed on the first circuit substrate with wiring patterns formed on the second circuit substrate. The first circuit substrate includes first wiring patterns capable of being connected to external wirings and second wiring patterns in a second wiring area apart from the first wiring patterns by a predetermined creepage distance to provide a sufficient isolation. The connector includes a contact array of a plurality of contacts, and a key which is formed at a position for separating the plurality of contacts of the contact array into a first contact group and a second contact group for (1) preventing a misconnection of the second circuit substrate and (2) separating the first wiring patterns from the second wiring patterns by the predetermined creepage distance. The first contact group is connected to the first wiring patterns and the second contact group is connected to the wiring patterns in the second wiring area.
