OK, so what is going on here because no matter what profile I pick for my
Epson using any product to print (not only Photoshop), I get the same
output. What's the point here in associating profiles to devices (in this
specific case, an Epson)???

I think this is fundamentally a user interface problem.

Clearly the appropriate profile to select depends on assorted settings in the print dialog box. The print driver should register all the assorted modes that result in different profile selection with ColorSync. Some drivers do this. The driver for my Canon i960 does. The user interface problem is that the mode names that show in ColorSync Utility have NO OBVIOUS relationship to the print dialog user interface. To this day I don't know what "PR1" and "PR2" correspond to for the Canon i960.

Things need to be done by driver/PDE writers:

1) Get consistent with the printer mode naming between the dialog boxes and the modes registered with ColorSync. This should be REALLY EASY to do. We are just tasking about some meaningful text labels here. Nothing more.

2) Actually use the profiles registered with ColorSync. This should be REALLY EASY to do. I wonder if this isn't commonly done because printer vendors don't trust third party control and they don't want to deal with support issues that involve what they consider to be incorrect profiles.

3) Provide feedback in AT LEAST the print dialog Summary pane of what profile will ACTUALLY be used by the driver when setting up the PDF to raster conversion (which is where the color mangling happens in tioga drivers).
