3. Plug the other end of the interface cable into the computer.
Since your printer is set up at the factory to use parallel
communication, you will need to change the DIP switch settings to
select serial communication. Two other serial interface settings,
baud rate and parity, may need to be set before your printer and
computer can communicate properly. See the section on setting DIP
switches in Chapter 3 for more information.
