Monday I printed a 16x24 image on fine art paper, matte ink on my 3880. Tuesday I could not get my print settings to be accepted, they kept being reset to a luster paper/photo black ink combination when I tried to save the settings. I've tried the Adobe recommendations and the Epson recommendations (involving updating the printer status monitor etc .... nothing works to let me now print from the rear feed, matte black ink and I've tried the Epson advanced b/w path as well as the photoshop (CS6) control with a specified profile. VERY Frustrating as there are 3 major companies involved and it is near impossible to determine who does what in the printing arena.
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.3), Epson 3880 printer, Photoshop CS6
