I recently updated from the 4880 to the 4900 for the ability to print on fine art papers, I am trying to print on Epson Water color radiant white out of photoshop. When I get to the print menu...I can select Epson watercolor profile (matte black) and have selected photoshop manages color but when I go to print settings,media is grayed out as well as matte black. I have changed to matte black on the printer and have updated printer firmware and lasted driver. Need advice as what to do next. Thanks in advance.
