Overview This document details the design of hardware and system firmware components that prevent communication between the HP printer network interface and the USB printing port. Physical Input – Output Hardware Isolation The HP printer ports and network interface are implemented as separate physical Input/Output (I/O) hardware devices. There is no Direct Memory Access (DMA) connection between the I/O hardware busses.
