Yes. Your problem isn't in how you're printing from Lightroom. That's  
the right (and only)
way to print - select the profile, ColorSync (in the Color Matching  
pane of the print dialog)
comes up dimmed and autoselected. Photoshop behaves the same way.  
Don't worry about that,
the "right" thing is happening underneath.

Your problem is that you've probably printed any NEW profiling target  
prints, using
Snow Leopard, incorrectly. If you've switched to Snow Leopard: printed  
targets (incorrectly)
and built profiles from the measurements taken from these incorrectly  
printed targets,
you'll end up with do-nothing profiles; and when you use these in  
Lightroom or Photoshop,
they'll "do nothing" and you'll end up with a dark, dull print that's  
essentially uncalibrated.

There's any easy solution to your problem. You need to start over,  
reprint your targets under
Snow Leopard, correctly this time, then measure and build new profiles.

This is the key: when printing the targets from Spyder3Print: you need  
to go into the Color
Matching pane of the Snow Leopard print dialog and choose "Epson Color  
Controls" there (not
ColorSync!) when you print the targets. In Spyder3Print, these radio  
buttons in the Color Matching
pane of the print dialog are selectable; they're not dimmed; and you  
HAVE to choose "Epson
Color Controls" there for the target to print correctly. AND, in  
addition, you also have
to use the "Off" setting in the 2880-specific section of the print  
dialog.

Do that: reprint a target; visually compare it to a target print  
you've previously made
under Snow Leopard; your new target print should be visibly darker. If  
so, your problem
is solved. Just remeasure the new target print, build a new profile,  
use that in Lightroom,
and you should get perfect prints.
