Abstract:
A printing system includes a terminal device that generates print job data, and a child printer that is configured to communicate with a parent printer that receives the print job data from the terminal device, where the child printer is configured to perform printing based on the print job data. The terminal device stores the generated print job data and transmits, to the parent printer, print job related data including the stored print job data and a plurality of pieces of access information for accessing the terminal device. The child printer requests a transmission of the print job data from the terminal device based on the plurality of pieces of access information included in the print job related data received by the parent printer.
Abstract:
Provided is technology enabling identifying the page of a color chart being measured while measuring the colors of the color chart, and generating color correction data. An information processing device 100 has a generator 121 that generates image data for printing a color chart 200 including, in part of the multiple patches, patches of an identification patch group 210 that represents page information by the sequence of patches in the group, the page information being at least one of the page number and order of pages in the color chart 200; an extractor 125 that extracts, from the color measurement results of the color chart 200 printed based on the image data, the page information represented by the patch sequence of the identification patch group 210 in the color chart 200; and an adjuster 127 that generates color correction data based on the color measurement results of the color chart 200.
Abstract:
Increasing the processing load on the server is suppressed in a network system in which response requests are intermittently transmitted from a client to a server. A network system has a client configured to transmit response requests at a specific time interval, and a server configured to send a response to the client according to a received response request. The server calculates a communication interval indicating an interval at which the client is to transmit its response request based on a factor affecting the processing load of the server, and sends communication interval information indicating the calculated communication interval to the client. The client transmits its response request at the time interval indicated by the communication interval information received from the server.

Abstract:
A printer apparatus that operates with power supplied by a power supply device includes: a printing unit that performs printing; a communication unit that is connected by USB to an external apparatus and supplies the power to the external apparatus; and a print control unit that causes the printing unit to perform printing in accordance with a print command received by the communication unit. When the printing unit performs the printing, the print control unit causes the communication unit to transmit a power-saving-enabling instruction that instructs the external apparatus to enter a power saving state.
Abstract:
An image processing device combines an image of a medium exposed to visible light and an image of the medium exposed to ultraviolet light so that parts printed with UV ink can be easily identified. A control device (image processing device) has an image acquisition unit that drives an image sensor and acquires a first image by imaging the face of a check when exposed to a visible first light, and acquires a second image by imaging the face of the check when exposed to an ultraviolet second light; a reverse image generating unit that generates a reversed second image by reversing light and dark in the second image; and a second synthesizing unit that generates a second synthesized image by combining the first image and the reversed second image. Because the reversed second image that is the reverse of the second image becomes an image that is light overall, a drop in the luminance and a drop in the contrast of the first synthesized image can be suppressed, and parts printed with UV ink are easily discerned.
Abstract:
An image processing method corrects an image acquired from a medium exposed to ultraviolet light and makes parts printed with UV ink easily recognizable. A control device acquires a first image captured by an image sensor from a check exposed to visible light, and acquires a second image captured by the image sensor from the check when exposed to ultraviolet light. The control device generates a first edge image by applying an image processing filter that extracts edges in the first image, and generates a second edge image by applying an image processing filter that extracts edges in the second image. The control device then finds common edges where a first edge extracted in the first edge image and a second edge extracted in the second edge match each other, removes the common edges from the second edge image, and outputs a second image from which the common edges are removed.
Abstract:
An image processing apparatus includes an image acquiring unit that reads the front surface of a medium irradiated with first light to acquire a first image, and reads the front surface of the medium irradiated with second light including ultraviolet rays to acquire a second image, by driving an image sensor, a first corrected-image generating unit that generates a first corrected image by decreasing brightness of the first image, a second corrected-image generating unit that generates a second corrected image by increasing contrast of the second image, and a synthetic image generating unit that generates a synthetic image by synthesizing the first corrected image and the second corrected image.
Abstract:
Delaying processing based on received commands is suppressed while preventing executing parallel processes involving operation of hardware. Servers can send printing commands and non-printing commands to a printing device. When a printing command is received from a first server and a printing command is then received from another server different from the first server while a process based on the printing command received from the first server is executing, the printing device does not execute the process based on the printing command received from the other server; but if a non-printing command is received from another server, the printing device executes a process based on the non-printing command received from the other server parallel to the process based on the printing command received from the first server.
Abstract:
A print control device, a control method of a print control device, and a recording medium storing a program enable easily configuring a peripheral device connected to a printer. A POS terminal that configures peripheral devices connected to a receipt printer has a device configuration selection unit for selecting a configuration of peripheral devices; and a device configuration screen display unit that displays a configuration screen for the peripheral devices based on the selected device configuration. Because a configuration screen for a peripheral device that is not connected to the receipt printer (a configuration screen that is not needed) is not displayed, the risk of creating confusion regarding the configuration of a peripheral device for the user can be reduced.
