The normal parallel port mode is the standard mode
EFAULT
for parallel port operation.
Parallel port outputs are 8-bits long. Inputs are
accomplished by reading 4 of the 8 bits on the
status register.
The parallel port operates in the enhanced parallel
port mode (EPP). The EPP mode supports
bi-directional communication between the system
and the parallel port device and the transmission
rates between the two are much faster than the
Normal mode.
