Parallel Interface Jumpers
There are three jumpers on the parallel interface. These jumpers
control some of the functions of the parallel interface.
These jumpers change settings that do not normally require
changing. Do not change these jumpers unless you understand what they
do and have a specific requirement.
To change the jumpers, you need to remove the interface from the
printer. Chapter 2 tells you how to remove and replace it.
