No matter what I do I get way to much MAGENTA

iMac is Catalina, photoshop cs6, profiles in order, 1430 Artisan epson,epson ink,epson paper. RGB images print with a heavy overcast even if I desaturate image. Change mode to Grayscale the same results.?? P.S. This doesn’t happen all the time…about 50% of the time? No rhyme or reason….just unpradictable ?
