I had same problem even after I got the replacement printer from Epson. It was printing fine until black ink ran out and replaced with generic ink which I always use, but nothing changed. After all the cleaning, the color ink ran out one by one and I had to replace all of them (costly!). Nothing worked.
Then I tried 'COPY' function on the printer, and printed in color. The image in black came out fine. So, I figured it's the software problem.
I was trying to print the form in PDF, but I couldn't print the B&W color document. Now, I am desperate to find the workaround, so I changed the printer's advanced setting in Adobe Reader to 'print as image' and printed it.
It worked! Again, it is a software glitch, I think, that Epson printer behaves differently in Chrome, Text, Adobe Reader, etc. I am not an expert, but I could print what I needed to print. So, 'print' to PDF, and print from PDF as an image.
FYI - I was doing all the trials on iMac.
