Medium steppers pulled from printers

[olskool]

So I pulled these from a big old printer the other day. They seem pretty clearly marked (if you know what the markings mean)
The photos are kind of blurry, but what the pinout is labeled as is
+24v
-24vpgnd
pgnd
sgnd
+5v
start
ready
clock
cw/ccw

I am assuming that this is a stepper and a driver wrapped up in one. Is that right? If so, how would I go about using it? I know in mach 3 there is a line for step and direction. is that synonymous with start and cw/ccw?

any thoughts would be greatly appreciated.

Not too sure if these will be of too much use. These motors rotate at high speeds, and have a massive deg/step rating. They're usually geared down massively inside the printer.
To my understanding:
START needs to be high
READY is a feedback signal from the driver
CW/CCW rotation depends on the voltage on that pin
CLOCK is probably fed with a squarewave inside the printer, which determines the rotational speed.
24V is for powering the motor, 5V is for the ICs
Hope this helps a bit

Nice table btw
