Abstract: The subject application is directed to a system and method for customizable device driver system for interfacing with a document processing device. A workstation and a set of operative functions of the device are interfaced via a core device driver resident in the memory of the workstation. Next, the core device driver is linked with at least one secondary function associated with the device outside the set of operative functions. A display corresponding to each of the operative functions is generated on the workstation. Secondary functions unique to the set thereof are stored in an associated memory. Selection data is received corresponding to at least one selected secondary function. At least one secondary function is retrieved from the memory according to the received selection data. Each retrieved secondary function is linked to the core device driver such that the secondary function is enabled and appears on the display.
