We got the GTX installed about 3 months ago. It prints well and is reasonably fast. Ink is $.31 per CC when purchasing the 700cc carts. The issue that we are having is the maintenance white ink that is wasted, this is a big problem. There was a firmware update that improved the waste but still too much waste. If this can be fixed it might be ok. If you were running the machine several hours daily the waste won't be as bad.
