Thanks for pointing out the situation. Yes I can work with 8 inks. I have been using QTR on 3800 and 3880 printers for some time now, primarily to make digital negatives.
Does the 9890 printer driver work with the 9900 printer hardware? I use the curve creator to modify the ink profile, set the gray curve, and install the corresponding Curve. I don't know how to install a Curve on a PC without using Curve Creator.
But the good news is I have eliminated the laptop hardware from the problem.
Thanks
John
