From what I remember, the Colorgrafx x2 ran with a Caldera or Onyx DFE, not from a regular PC. The drivers would have been built into the DFE software itself (From what I remember).
Caldera and Onyx are still around, but it will be pretty hard to get info and software (or the hardware) to run a 16 year old inkjet printer or its DFE.
I have a ColorgrafX X2 printer and i am trying to get it to run.
So far i have set up an xp maschine with a SCSI-2 controller, the controller sees the printer an asks via the hardware wizard for drivers.
I get the this for every SCSI ID. Its asking for "XEROX X2 54 SCSI PROCESSOR DEVICE"
Looking for a driver online no luck so far.
If anybody could help me find a solution i would be very happy.
