Doyle,
Any advice on the best way to remove all traces of the driver before installing?
Thanks.
Update,
I removed the old driver (after creating a bootable backup!) by first removing the printer in system preferences, and then going to HD>Library>Printers and trashing the Epson folder. I also edited the InstalledPrinters.plist file to remove the Epson printer (probably unnecessary as this file doesn't seem to be used by the current OS). I then downloaded and installed the 6.11 driver and the v7 updater (which confusingly, and as noted by Epson, does not update the driver version number).
Cut to the chase. New targets printed in CS5 look VERY different than the ones printed before the driver reinstall, and much more like what I am accustomed to. However, they do not look anything like the targets printed by eye-one match. The PS targets are much more saturated than the pale targets produced by eye-one. Tried printing a target in CS4 and visually it is identical to the target from CS5.
to be continued...
