A device driver, for generating control commands for driving a peripheral, includes a status store configured to store state data, which identifies a current state for each of a number of functions of a peripheral. The device driver also includes a driver engine that is operable to generate control commands for driving a peripheral in accordance with state data stored in the status store. The device driver further includes a user interface generation module for generating display data that defines graphical user interface displays in dependence upon data stored in the status store and is responsive to user selection of graphical elements in generated user interface displays to update data stored in said status store. The user interface generation module includes a graphics store configured to associate each state of each of said number of functions of a peripheral with an item of graphics data defining a graphical element. The user interface generation module also includes a page store configured to store a user interface template, which includes layout data defining an arrangement of place markers for graphical elements of a display and data associating at least some of said place markers with functions of a peripheral. The user interface peripheral also includes a display data generation module responsive to the updating of data in the status store to generate display data defining a graphical user interface display. The graphical user interface display includes graphical elements defined by graphics data associated with states identified by state data in the status store for functions associated with place markers by the user interface template. The graphical elements are arranged in accordance with the layout data of the user interface template. |
