Hmmm..._might_ be a piece of the puzzle.
I'm generating the targets with Argyll. They're completely untagged at that point. At the other end, I'm using Argyll to convert TIFFs from whatever working space to the printer's space; those TIFFs are tagged with the printer's space. If the targets are getting tagged as sRGB and then converted to something else before the printer sees them, that would explain an awful lot. But how, then, to stop such idiocy?
If I open the chart I profiled and assign it the profile I created from it, onscreen it's as good a match as one gets. When I open an image converted to and tagged with that printer profile, onscreen it looks practically indistinguishable from the original. But when I print that image, everything goes off the rails. (And, as verification, if I assign such an image some other profile, onscreen it goes wild.)
