Microsoft recommends against using IEEE 1284.4 interfaces for print devices. Microsoft-supplied drivers that support IEEE 1284.4 interfaces might be removed from future versions of the Windows operating system.

All class installers are included in the Class Installers / Hardware Compatibility macro component.

Every driver is associated with a class installer that the driver requires for its installation. If the correct class installer is not installed before driver installation, your device will not work properly.
