The thing that is puzzling here is that in order to print using ABW from recent versions of Photoshop, you need to print using "Printer Manages Colors", which precludes you specifying an ICC in the Photoshop print dialog. At least that's the case in Windows and I'm fairly sure that that's the case in OS X as well.
I seem to recall that in very old versions of the Epson Driver on OS X, you specified one of Eric Chan's ICCs in the ABW settings, rather than in the Photoshop print dialog. Epson removed that option many years ago. I don't think Windows users ever had it. Perhaps I've got this wrong and back in those days you didn't have to specify "Printer Manages Colors" in order to access ABW, and so you could specify an ICC in the Photoshop print dialog, and the change was removing the option to do that. This point of history is not clear to me, since I never saw it in action.
The Eric Chan instructions on the page that Bruce linked to are not clear on this point, probably because they didn't need to be at the time they were written. They say "This makes it easy to get screen-to-print matching when using the ABW driver: you can use exactly the same workflow as when printing color images, from any printing application (Photoshop, Lightroom, etc.). The only difference is that you select an ABW profile instead of a RGB color profile." Could be either.
So how is Bruce using Eric Chan's ICCs in the modern age? Is he doing the conversion to the ICC manually in Photoshop before then printing using "Printer Manages Colors"? This is how you would use a QTR-generated ICC. I'm not aware of any alternative. Hence my question about workflow, which was not answered by that link.
