However, if the software really is not changing the print in response to edits, the problem is none of these things.
Since you have Adobe, I suggest you print from Lightroom as a test. Set the software to control color, set output sharpening to standard, and set the resultion to 360, which is the native Epson resolution. Print once. Then put an extreme curve adjustment on and print again. I'll bet that the two prints will look very different. If they do, then there is some problem either with how you are printing from Photoshop or a problem in your installation of photoshop (which you could probably fix by uninstalling and reinstallling the software).
