There are two more aspects to remember in this matter:
If you are using a notebook machine, you can not install a ISA card so it would be
better using the LPT port.
And, if you are going to use this board / port for driving step and dir signals to a
stepperamplifier or servoamplifier. Then, what will be the best way to do this. Either to
have a long cable between the pc and the optocupler board or have a long cable
between the opto-board and the amplifier. This will be a bigger problem with large
machines. (This cables can be 3 to 10 yards long.)
Just a matter to remember.
