Photoshop :: Image Editing Workflow For Fine Art Printing

I'm developing a workflow and I would like to see how the images of professional photographers look like in PS at the end of the process ... ready for printing.
 
Here is my workflow in PS for B&W photo (Hue/Saturation adjustment layer is not needed for a B&W photo as known):
 
After making all tone and color adjustments in LR, I open the image as a smart object in PS ... and rest is on the above image, showing my layers panel in PS at the end of the developing process.
 
At the end of the work, if I print with PS, I select all the layers and convert them to a smart object together and I apply output sharpening ... but if I print with LR, I save and close the file without output sharpening and I use the sharpening options on the print module in LR.
