Thank you for your comments. As noted in the Subject I am referring to the sliders in Lightroom CC 2105. I can print directly from Lightroom CC to a "QTR printer" via Print Settings. I do not use Roy's print tool.
Typically I do all of my QTR printing from Photoshop (currently CC 2015) however, because I wanted to print two up on large paper I decided to try printing from Lightroom.
May I assume that I that in summary your response might be that the sliders have no effect a print to a "QTR printer" from Lightroom.
Thanks again.
