Abstract: An indicator detection method includes operating in a first mode and operating in a second mode. The first mode includes detecting a position of a first indicator on a operation surface by detecting first light emitted by the first indicator, emitting second light by a light emitting device, and detecting a position of a second indicator on the operation surface by detecting reflected light of the second light reflected by the second indicator. The second mode includes reducing a light amount of the second light when it is determined that the first indicator is in contact with the operation surface, and detecting the position of the first indicator on the operation surface by detecting the first light in a state where the light amount of the second light is reduced.

Abstract: In a control system in which a terminal with a browser and a control device communicate through a network, the system and control device are made compatible with a configuration in which the devices communicate through a network. When establishing a connection between a tablet device 10 and a control device 11 in the POS system 1, both devices store identification information related to the connection, and when reconnecting after the connection is broken, reconnect based on the identification information stored by the devices.

Abstract: A device control system has a terminal 3 with an application 31, and a printer 5 that controls a scanner, or other device. The terminal 3 sends a request written in XML generated by the application 31. The printer 5 receives the XML request, and the terminal 3 receives an XML response. If the terminal 3 requested control of the scanner in the XML request, the terminal controls the scanner.

Abstract: A print data processing system 101 has a plurality of print data distribution devices, and an information processing device that receives print data from the plural print data distribution devices. The information processing device initiates a reception process unit appropriately to the plural print data distribution devices. Each reception process unit queries the related print data distribution device for print data, receives the print data when print data is on the print data distribution device, and stores the received print data to a shared storage area.

Abstract: Appropriate use of a device by each terminal is enabled based on plural terminals being able to use the device. A control system 1 has a first tablet terminal 101 (terminal) that runs a web browser; a device DV that outputs data input to the web browser, or to which data output from the web browser is input; and a printer 11 including a device communication unit that communicates device input/output data with the device, a terminal communication unit that communicates the device input/output data with the terminal, and a device management unit 20d that manages the relationship between the first tablet terminal 101 and the device DV.

Abstract: A device control system has a terminal 3 with an application 31, and a printer 5 that controls a scanner, or other device. The terminal 3 sends a request written in XML generated by the application 31. The printer 5 receives the XML request, and the terminal 3 receives an XML response. If the terminal 3 requested control of the scanner in the XML request, the terminal controls the scanner.

Abstract: A device control system has a terminal 3 with a web browser 31, and a printer 5 that controls a connected device. The terminal 3 calls an object that controls a device and is instantiated by the device API 33 to support the device, and sends a request to the printer 5, by the web application 32; and the printer 5 executes a device control script 502 that controls the device, receives requests sent through the device API 33, and controls the device.

Abstract: A device control system has a terminal 3 with an application 31, and a printer 5 that controls a scanner, or other device. The terminal 3 sends a request written in XML generated by the application 31. The printer 5 receives the XML request, and the terminal 3 receives an XML response. If the terminal 3 requested control of the scanner in the XML request, the terminal controls the scanner.

Abstract: Terminals connected to a POS terminal can execute appropriate processes using functions of a browser. A POS system 1 has a first tablet terminal 101 that runs a browser; a second tablet terminal 102 that runs a browser; and a POS control device 11 that is communicatively connected to the first tablet terminal 101 and the second tablet terminal 102, and has a communication unit 20b that sends data received from the browser running on the first tablet terminal 101 to the browser running on the second tablet terminal 102.

Abstract: A POS system SY has a card reader 4 that reads data; a printer 2 connected to the card reader 4 and receiving data input from the card reader 4; and a tablet terminal 1 connected to the printer 2. The tablet terminal 1 has a POS application 52 for executing a transaction process, a payment application 53 for executing a payment process based on data input to the printer 2, and a control unit 110 that controls the POS application 52 and payment application 53.

Abstract: A data processing apparatus includes a first interface to which a device which reads data is connected, a second interface to which a terminal apparatus is connected, an identification information transmission unit that transmits identification information to the terminal apparatus, and a control unit that when the data read by the device is input to the first interface, determines an association of the device and the terminal apparatus based on a correspondence of the read data and the identification information transmitted to the terminal apparatus.

At the terminal, the device control by the application through the controller is established after establishing the device control by the controller.

Abstract: An interface board 3a used as a print control device has a reception unit 310 that receives print data; and a print control unit 320 that applies redirection control to send the print data to a second printing device different from the first printing device when the first printing device, which is the first print destination of the print data, is unable to print. In redirection control, the print control unit 320 sends the print data and additional information to the second printing device. The additional information includes status information causing the second printing device to print the status of the first printing device.
