New for IEEE 1284.4 Devices
The Driver Development Kit (DDK) documentation for IEEE 1284.4 Devices is provided to support existing devices only. Microsoft recommends that hardware vendors design new multifunction print devices using composite USB interfaces, and strongly recommends against using IEEE 1284.4 interfaces. This documentation might be removed from all future versions of the DDK. Microsoft-supplied drivers that support IEEE 1284.4 interfaces might be removed from all future versions of the Windows operating system.
