newby question about printing digital neagtives with QTR on PC

 

I am making digital negatives and need some help. I will explain below how I got?to this place,?but my immediate question is this: I created a .quad curve on a Mac using Richard Boutwell's Quad Tone Profiler. I want to use this curve to print on a P900 using QTR on a?PC. The GUI in QTR v2.8.2 does not accept 10 inks. Can I simply edit the .quad file by deleting the V and MK curves to make it work with QTR? Or do I need to run QTR .exe files from the command window? If so, which .exe file should?I run and what are the command arguments to identify the printer, paper, feed, etc?

Ok, so why am I trying to print with the PC? I have two Macs, one running iOS 14.7 and one running iOS 10.14. I cannot get either of these to print using the QTR Print-Tool 2.3.4 with the front feed on my Epson P900. I continually get an error saying that "The paper do not match the settings on the printer." I suspect that this is because Print-tool does not have any options for selecting the front/rear feed or the type of paper, so the printer is confused. When I print from the PC using QTR, I have both feed and paper options available.?

I can print from the Mac using Print-Tool if I use the top feed, but I prefer the front feed because the quality of the digital negatives looks better. Although I do not have serious problems with pizza wheel marks, there is some banding and unevenness with the top feed - especially with negatives that need heavier ink loads for carbon transfer printing. It is less of an issue with Palladium. The negatives printed with the front feed - No Eject - are better.

Any advice would be welcome.?

QTR on a Mac (14.7 - 15.2): Front feed is selected via: Printer Options > QuadToneRIP > Paper Feed. This works in Print Tool.?
