Abstract

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

First claim

1 . A printer for a point-of-sale (POS) system, the printer comprising:
a connector configured to connect to a device responsive to device-control commands; a communication interface configured to communicate with a terminal, to receive a markup language request from the terminal, and to send a markup language response to the terminal; a controller configured to interpret the markup language request received from the terminal, and to control the device using appropriate device-control commands to execute the interpreted markup language request, the printer being further configured to encode any response from the device as a markup language response and to send the markup language response to the terminal; wherein the device-control commands are not a markup language.

2 . The printer described in claim 1 , wherein
the markup language response includes data denoting a result of device control.

3 . The printer described in claim 1 , wherein
when the printer receives from the terminal an establish communication markup language request to establishment a communication link with the printer, the printer sends to the terminal a markup language response to the establish communication markup language request.

4 . The device control system described in claim 1 , wherein
in response to the printer receiving from the terminal an open markup language request to open communication with the device connected to the printer, the printer sends to the terminal a markup language response to the open markup language request indicating whether a communication link with the device is established.

5 . The device control system described in claim 1 , wherein
in response to the printer receiving from the terminal a close markup language request to close communication with the device, the printer sends to the terminal a markup language response to the close markup language request indicating whether communication with the device is closed.

6 . The printer described in claim 1 , wherein the communication interface is a computer network interface.
