servo control via lpt problems

Hi all i am working on a small project in VB, Controlling Servos by voice. everything is working great except for one thing. If i use one power adapter to control more than 1 servo, then following happens While 1 servo moves , second servo seems to get enough of a voltage fluctuation that it will move one way or the other. so currently for this to work for me, i need to have a separate power supply for each servo, then everything works great. TIA Mike

Try adding a resistor in series of each servo. Or/and add a small mica cap on the power pins of each servo to shunt to motor noise generated by the servo's. Try a .1 Uf cap first to see if it helps it.
