oki 5200 bad color

[paintguy]

I recently got an OKI 5200n led printer and am trying to print on an older mac using 10.3 and the color prints come out a bit on the magenta side and the white areas are a bit greyish magenta. I am trying to figure out if there is a way to get a better icc profile or a way to go into the software and manually tweak the color output to get a closer color match to the screen. I realize that this is not a postscript printer and that could have something to do with the poor print quality. I called okidata and they told me a couple settings to try from the print diologue boxes but it only helped marginally. I am wanting to print people pictures mostly and the purplish cast and lack of clean whites and overall darkish tone look very poor. Any help in finding a way to callibrate the printer would be great. Thanks, Doug
