Hello folks. I have a frustrating issue with two current gen. Epson printers. At home I have a 2880, and at work, a 4880. From Lightroom, I'm printing B&W on the 2880, using Moab CFG, ICC profile, colour settings, I get perfect and predictable neutral results. Very slight tweaking involved due to high brightness of (calibrated) LCD screen.

The problem comes with trying to get the same results from the 4880. Using all the same settings, gives me a slightly purplish/magenta print. To get even close to the 2880's results, I've had to resort to using Adv. b&w settings (warm/darker), and then fiddling even more with the exposure; the tonal relationships/ exposure are all different though.

Does anyone have clue what's going on here?
