It is almost always recommended to let Photoshop do the color management when printing and turn the printer color management off. Photoshop, it is asserted, does a better job. However, when I print a multi-colored test image (David Brooks' 4x5 TEST.jpg) both ways on my Epson Stylus Photo 2200, I can't see any difference, no matter how hard I try (I have used high-quality lighting with a very high CRI, normal incandescent lamps and compact fluorescent lamps to evaluate both images).
What method would you recommend and why? Why don't I see a difference? Your inputs will be very welcome.
