A system in which a terminal device communicates with a server and processes data enables the terminal device to continue processing data even when a communication fault occurs. A data processing system includes a server that stores a POS application; a processing device that stores a POS application; and a tablet that connects to the server and executes the POS application through a web browser when a terminal communication path satisfies a terminal communication condition, and when a terminal communication path does not satisfy the terminal communication condition, connects to the processing device through a process communication path based on information indicated by the POS application.

Data processing system, data processing method, and printer

A system in which a terminal device communicates with a server and processes data enables the terminal device to continue processing data even when a communication fault occurs. A data processing device has a data storage unit storing data processing device-side master data, connects through a server communication path to a server, updates the data processing device-side master data stored in the data storage unit based on server-side master data stored by the server, connects to a tablet through a process communication path, responds based on the data processing device-side master data stored by the data storage unit to a master data transmission request sent by the tablet, and receives the process information sent by the tablet.

Printer and data processing method

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 deviceand a control devicein the POS system, 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.

Control system, control method of a control system, and control device

When able to communicate with a control server, the tablet terminalof a transaction processing systemcommunicates with the control serverand executes a process using server-side data stored by the control server. When unable to communicate with the control server, the tablet terminalcommunicates with a recording control device, and executes a process using control device-side data stored by the recording control device. If the recording control deviceis not on, the tablet terminalsends to the recording control devicea start command causing the recording control deviceto start.

Network system, control method of a network system, and terminal

A POS terminal has a server-function unit with a server function, and a client-function unit. When able to communicate normally with the control server, the client-function unit communicates with the control server as a client of the control server, and executes processes with the control server. When unable to communicate normally with the control server, the client-function unit communicates with the server-function unit as a client of the server-function unit, and executes processes with the server-function unit.

Network system and control method of a network system, and a control device

A device control system has a terminalwith an application, and a printerthat controls a scanner, or other device. The terminalsends a request written in XML generated by the application. The printerreceives the XML request, and the terminalreceives an XML response. If the terminalrequested control of the scanner in the XML request, the terminal controls the scanner.

A system having a server and a control device that connects to the server through a global network and executes processes referenced to data stored on the server can handle events in which the control device and server cannot communicate with each other. When a control device-side product master database stored by a POS terminal is updated while the POS terminal is unable to communicate with the control server, the POS terminal communicates with another POS terminal through the local area network LN and causes that other POS terminal to update its locally stored control device-side product master database.

When able to communicate with a control server, a POS terminalupdates a transaction information management databasewith transaction information data based on a transaction process. The POS terminalstores the transaction information data when not able to communicate, and when communication is enabled again, causes the control serverto update the transaction information management databasebased on the stored transaction information data. If queried for specific transaction information data while unable to communicate with the control serverand the requested transaction information data is not stored locally, the POS terminalqueries other POS terminalsthrough the local area network LN for the specific transaction information data.

Appropriate use of a device by each terminal is enabled based on plural terminals being able to use the device. A control systemhas a first tablet terminal(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 printerincluding 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 unitthat manages the relationship between the first tablet terminaland the device DV.

Control system, and information processing device

A device control system has a terminalwith a web browser, and a printerthat controls a connected device. The terminalcalls an object that controls a device and is instantiated by the device APIto support the device, and sends a request to the printer, by the web application; and the printerexecutes a device control scriptthat controls the device, receives requests sent through the device API, and controls the device.

In a system having a control server and a control device that connects to the control server through a global network, the control device can appropriately handle processing when normal communication with the control server is not possible. The POS terminalof a transaction processing systemhas a client-function unitconfigured to send authentication information to a control serverand request authentication, and acquire and store an access code generated by the control serverwhen authentication is successful. When normal communication is not possible with the control server, the client-function unitcommunicates with the server-function unitas a client of the server-function unitbased on the stored access code, and executes processes with the server-function unit

Terminals connected to a POS terminal can execute appropriate processes using functions of a browser. A POS systemhas a first tablet terminalthat runs a browser; a second tablet terminalthat runs a browser; and a POS control devicethat is communicatively connected to the first tablet terminaland the second tablet terminal, and has a communication unitthat sends data received from the browser running on the first tablet terminalto the browser running on the second tablet terminal

POS system and printing device

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.

Data processing apparatus, POS system and control method of the POS system

In a control method of a control system including a terminal configured to execute an application, a device configured to send or receive data, and a controller connected to the device, a request for a device control is transmitted from the application to the controller. At the controller, the device control by the controller is established after the controller receives the request. At the terminal, the device control by the application through the controller is established after establishing the device control by the controller.
