You would need to write a macro for that, how you connect the hardware will depend on whether you have enough I/O on the parallel port or not. You could use a PLC or PoKeys or ModIO etc to get any extra  I/O you need. PLC would be my choice as it will allow you to do most of the feed in the ladder itself which will make the macro a lot easier also the PLC can be connected direct to the 24v which is likely what the barfeed will be.

If that is enough I/O then yes but you will more than likely need powered breakout boards as the PP is unlikely to have enough to operate the relays.

I make this 16 opto-isolated solidstate relays, they are activated by PP, an can carry up to 60 Volts DC 10 A max, the valves on the machine is on 24 V, - But I am confused about activations and de-activations of valves - about writing a macros....

ActivateSignal(OutPut*) 
DeActivateSignal(OutPut*)

are what you will likely need, obviously the * is the output number you are using in Ports and Pins for that function.

As for writing the macro then best thing is just to look at some of the macros in the macro folder and also look at the VB Buttons in the wizards and it will help you out.

Ray is writing a manual at the moment so when thats done it will help a lot.

You could also probably do it via a Brain which might make things easier but they also have a learning curve.

I think I have never seen a hydraulic piston controlled via a stepper motor.

That is same like servo wheel in the cars, steppers is like drivers hands, hydraulic do move directions...of front wheels..
