These XMLs store request and response data for each device controlled. This type of XML is a child element of the <data> element of the <device_data> message and specifies data to control a device. Components of the message data differs depending on the device type. Specify the type of message data with the <type> element, and then specify data for the child element.

Printers and customer displays can use the control XMLs to control print data and display.

Refer to Supported Printers by XMLs for the types of devices available for each printer.
