Hum...I seem to do just fine printing from Lightroom and I do know a bit about the Print module since I helped design it and licensed PhotoKit output sharpening for use in LR's printing. And yes, you really only need 3 levels of sharpening tuned for either matte or glossy paper. Bruce Fraser pretty much wrote the book on image sharpening (literally wrote a book on sharpening which I updated after his passing) and because of that, Adobe licensed it for LR.
However, it's the printing workflow from LR that is the real benefit...and seriously, you can't use LR's local controls? Do you actually know how to use them?
Well it doesn't work for me. And I know a bit about fine prints . . . Just because something "works for you" doesn't mean there aren't better options out there.
Lightroom Local Tonal Controls: Yes, I can use them, but they are the least intuitive and biggest pains in the anus. And, since there are better options out there, I don't bother with dumbed-down software like Lightroom and the slew of plugins needed to get what I consider decent results from it.
The magical-mystical sharpening algorithms: Judging from the few pictures on your site, I'd argue that they are all over-sharpened. I've never seen one of your prints in person, but I assume they are over sharpened as well. I know your are well regarded as being the one who "wrote the book" on a lot of this digital stuff (I even bought your printing book a few years ago). I also realize you have to stick up for those controls because you helped helped design some of them and licensed the sharpening software to Adobe. But, that doesn't make it good, and just because someone literally wrote the book on a subject doesn't mean that it shouldn't be reevaluated. Every time someone sends me a file to print that has gone through one of these sharpening plugins, I have to ask them to send me a file that hasn't been sharpened so I can make a print that isn't peanut brittle. People can talk all day about spatial frequencies, deconvolution sharpening formulas, and resizing algorithms until the fixer's exhausted, but that doesn't mean the print looks good when its hanging on a museum wall.
