Figure 31 - Selecting the LPT Port
Correct LPT Mode
If communications are not working, then it is possible the LPT port mode is set improperly. It is
recommended to use the simple, Output-only mode of the LPT port. This can be set in the BIOS
of the computer. Common terms for this desired parallel port mode are “Normal,” “Output,” or
“AT.” It is possible to enter BIOS setup during the initial boot up sequence of the computer.
