Caution
Danger of damage being caused to the device
Connect printers to the parallel port only when the device on the LPT 1 port is
turned off (printer likewise turned off).
Make sure you are using the correct port. If you interchange the connectors,
or use wrong connecting cables, the port might be damaged.
Before inserting the connecting cables, the static charge of your body, the device
and the connecting cables must be brought to the same level. You can do this by
briefly touching the metal housing.
Use the original cable to establish the connection.
