Major Code:

IRP_MJ_DEVICE_CONTROL

-description

The IOCTL_INTERNAL_INIT_1284_3_BUS request initializes and assigns an IEEE 1284.3 device ID to all the 1284.3 daisy chain devices that are attached to a parallel port.

Windows 2000 supports from zero to four daisy chain devices and an end-of-chain device simultaneously attached to a parallel port. Windows XP supports from zero to two daisy chain devices and an end-of-chain device simultaneously attached to a parallel port.

Note   This request is included primarily for test purposes, and Microsoft does not recommend using it during the normal operation of a parallel port.
 
For more information, see Device Stacks for ParallelPorts and Devices.
