I didn't mean as a direct cause for what Mark is seeing but the 
reason why drivers are different for both printers with the 
possibility that something like this happens.

One pixel extra to shift the image enough to get rid of the 
interpolation artifact in a round object at a certain place in 
that image that happens to be an eye that catches the attention 
of the viewer. It could be that for 360 images with the same 
content but the eye at another place this artefact wouldn't show. 
It may have happened enough times where it did go by unnoticed. 
Mark used Imageprint on the 9000, its extrapolation can be 
different to the Epson 9000 driver, can be different to the 9600 
driver in that RIP, can be different to the Epson 9600 driver. 
Part of the differences in the drivers is based on the hardware 
differences of the printers, other differences are there because 
newer and better algorithms are used in the 9600 driver. Very few 
drivers and even RIPs get a renovation when new algorithms are 
introduced for new printers, one is lucky when old printers get a 
new driver for a new OS.

The one pixel shift is something to remember.
