Servo motors are not too difficult to drive. Google Elm Chan, talented guy, he's got a simple AVR based servo driver that ought to be capable of running the printer servos with external encoders. Not sure if they output a standard quadrature signal but the code could be tweaked to deal with whatever they do put out.
