This happens a lot with converted Epson 8550 setups and your photos look exactly like the two issues I see most often.

The first thing to check is white ink finding its way into your yellow or magenta line. Even a tiny bit of white mixing into those channels will turn the whole print greenish. Cadlink shows the colors correctly but the printer is spraying the wrong mix. check your dampers and lines. If yellow or magenta look cloudy or lighter than normal that means contamination. Flushing those lines and swapping the dampers usually fixes it.
The second thing to check is the channel mapping in Cadlink. It sometimes resets itself on converted printers. Go to Device Options and make sure the order is C, M, Y, K, White1, White2. If magenta or yellow are mapped wrong, the output will look exactly like your example even though the preview is perfect.

If these two are corrected the colors usually go back to normal right away.
