You're right, it wouldn't work.  The key word here is "printer" port.  You
have to connect to a "serial" port.  The printer port is a Centronics type
connection (parallel) that is NOT compatable with the serial connection
needed.  The printer port can be easily found in that it is the 25 pin
female "D" connector.

If you are currently using the serial port on your system, you will need
to add another one.
