That means that the drive is not enabled.

As a first step, just remove any wires to the drive "enable" pins. These are typically a "disable" and when connected to the parport the turn _off_ the drive.
There is no point wiring the enable on a stepper driver, you might as well save the parport pins.

f**k

The microstep dip switches were set to NC. My bad, sorry.
Your help forced me to triple check everything. I thought NC = nominal, no microstepping, not "not connected at all".

Thank you both!
