There is nothing wrong with the printer or drivers. Something is wrong with Photoshop CC. The error box says:
"There was an error opening your printer. Printing functions will not be available until you have selected a printer and reopened any documents."
I have the SAME PROBLEM. IT'S DRIVING ME CRAZY.
I was on tech support for HOURS with Epson trying everything.
I think adobe is doing something because when I transferred a file from
one computer to another it seemed to corrupt that other computer
which then couldn't print anything.
