Interface type and parity
If your computer is set up for serial communication, you need to
change DIP switches 2-5 and 2-6 so that your printer and
computer can communicate properly. These two DIP switches
control the interface type and parity. (You may also need to select
a different baud rate. See the following section on baud rate.)
The table below shows the DIP switch settings for a parallel
interface, and for a serial interface with odd, even, or no parity. If
you don’t know what type of interface your computer requires,
check your computer manual. Also check your computer manual
to make sure your computer and printer have the same parity
setting.

Baud rate
Besides selecting serial interface and parity, if your computer is
set up for serial communications you may also need to change the
baud rate setting. Baud rate is the rate at which the printer
receives data from the computer.
The table below shows the DIP switch settings for the printer’s
four baud rate settings. Check your computer manual or
application program for the correct baud rate setting. Your
computer and printer should always be set to the same baud rate.
