Resolution:
Called up Epson tech support. Tech had not heard of this problem, but said that for some reason EMI was having trouble communicating with the printer. Recommended to uninstall EMI, go to Epson web site and download EMI from there. I exported a few emy2 files first for media types I created for Canson papers. After install, everything is working as expected, imported the emy2 files. Did the software update to 2.2.3 through the Epson Software Updater and everything still works fine. Solved! I don't think I have ever run into a problem like this, especially because I was able to print without problems.
