The system-supplied bus driver for parallel ports creates a physical device object (PDO) that represents each parallel device that the bus driver enumerates on a port. The system-supplied function driver for parallel ports creates a functional device object (FDO) that represents each parallel port enumerated in the system. The executable image of Parport in Windows XP is parport.sys. In Windows XP and later, Parclass is removed, and Parport provides the function of both the parallel port function driver and the parallel port bus driver. The operation of Parclass and Parport is closely connected through Internal Device Control Requests for Parallel Ports and parallel port callback routines. The executable image of Parport is parport.sys. Parport is the parallel port function driver. The executable image of Parclass is parallel.sys. Parclass is the parallel port bus driver for devices that are attached to parallel ports. Windows 2000 includes the following drivers:

Microsoft does not provide parallel drivers for 64-bit versions of Windows. This section describes the features of the system-supplied parallel drivers for parallel ports and devices that are attached to parallel ports.Įxcept for 64-bit versions of Microsoft Windows, Windows 2000 and later provides a parallel port function driver and a parallel port bus driver for Plug and Play devices that are attached to a parallel port.
