It depends on what mode you will be using. If you want to use the port in
read/write mode, you just leave the cable intact. If you want to use the
port in normal mode (which is by far the easiest to use) you have to
attach the data pins of one port, to the control and status pins of the
other. Look at
for all the details one how the set it up.
It might be wise to use a somewhat different approach. The page says you
can take input on nine pins and chooses to let the ACK pin to be one of
them. You might want to free that one however, since it's the one that
generates interrupts and therefor is very useful for flow control.
