So ACPU will not accpet a CMYK document? Never tried it, I always try to print such data using the product that built the target within that application.
Here's an old trick from the ColorBlind days that may work.
Open CMYK doc in Photoshop.
Split Channels.
Delete K channel
Merge channels back into RGB.
As I said, in the old days, that was a kludge to print CMYK data from ColorBlind in cases where you couldn't handle a four channel CMYK doc. As to how the measurements resulting from reading such a print would work in modern ICC software, I don't know. Again, best to print it out of say i1Profiler or whatever application built the target. There's no reason we should have to depend on Adobe and Photoshop to print something an ICC color profile app should do in the first place.
I suspect the big issue is the printer driver! The Epson driver doesn't like CMYK data, it expects RGB. You probably need another driver (or what some often incorrectly call another RIP). ImagePrint comes to mind.
