ABSTRACT:
A computer system and method uses script-based device drivers for operating hardware devices. The script-based driver architecture comprises a scripting driver, a script engine, and a driver script for a given hardware device, such as a scanner. The driver script is generally a text file containing a sequence of programming instructions defining the operational behavior of the hardware device. The scripting driver exports a set of objects whose functions can be called by the driver script to communicate with and control the device. When a request to operate the hardware device is received by the scripting driver, the script engine interprets the programming instructions in the driver script corresponding to the request and invokes the functions of the scripting driver objects called by the programming instructions to carry out the requested device operation.
