well joy -- i got a Mac Pro 8core (20gb ram) installed from scratch ‚ 10.7.4, and CS6 (Ps Extended)

i got through Epson's abominable downloads page and loaded their

Printer Driver v8.66

Mac OS X (v10.7 - v10.7.x), Mac OS X (v10.6), Mac OS X (v10.5.8)

epson14623.dmg - 60MB - posted on 02/17/12

Common Updater v7.0 (if the Lion driver even needs it?)

Intel-based Macs with OS X (v10.5 - v10.6.8)

epson13884.dmg - 13.6MB - posted on 05/13/10

File> Print doesn't list any Epson profiles (I have PhBK ink installed and successefully printed a nozzel test)

however, with sRGB set as the print profile, I get the profile I want in Printer settings

ANY IDEA WHY File> Print doesn't allow me to select my Epson profile?

okay, i figured out Advanced Media Control, what i was actually looking for was Printer Settings> Advanced Color Settings

Epson color management is off there (as expected)

i guess the only thing stumping me now is File> Print> Printer Profile (whar's my Epson profiles?)

can someone please explain the new behavior -- what am I supposed to select there under Photoshop Manages Colors work flow?

i just installed the Epson 8.66 driver onto my 2011 Macbook Pro 10GB ram (another 5-day-old start from scratch 10.7.4 install, CS6 just installed today)

File> Print> "Photoshop manages colors"> "Printer profile" (also has no Epson profiles available)

also, "send 16-bit data" there is greyed out, too (a 16-bit RGB document is open)

Photoshop CS6, PS13, x64 appears to be unusable/broken under OS-X Lion 10.7.4 and the latest Epson software in the classic Photoshop Manages Colors work flow (Source Space to Print Space) -- seeing is believing.

+++++

Geoff the kiwi, i have little doubt the profiles are installed somewhere as they show up Printer Settings> Basic> Media Types -- but i followed your diagram to the ICCProfiles folder and here is a screenshot what I see:

and here they are searched

Geoff the kiwi, i appreciate your interest, i think we can rule out that the Epson profiles are installed and my machine meets Ps requirements:

and the driver

if it wasn't acting the same on two 5-day-old start-from-scratch installs with all updaters and maintenance ran - i might think i missed something - but i honestly don't know what it could be when Ps> File> Print grays out "Send 16-bit Data" on an sRGB 16-bit Source Profile and no Epson profiles with "Photoshop Manages Colors" selected

i also didn't get the Epson profiles using aRGB and sRGB 8-bit

i can try the 8-core again in the morning, but i don't think it will change from the results i posted this afternoon...

and View> Proof Setup: Device to Simulate doesn't have any of the Epson 9880_7880 profiles available

EASY SOLUTION-FIX FOR THE MISSING EPSON ICC PROFILES OSX LION CS6 PHOTOSHOP:

Hard Drive> Library> Printers> EPSON> InkjetPrinter2> ICCProfiles> Pro9880_7880.profiles (show package contents)> Contents> Resources (contains the default OEM Epson ICC Profiles)

Manually drag a "Copy" of the Resources folder into: HD> Library> ColorSync> Profiles

Restart Photoshop (and the Epson profiles appear under Printer Profile drop down menu with "Photoshop Manages Colors" print work flow option selected)

You don't need to install the Epson Common Updater v7.0 for Lion, only the 8.66 Epson driver noted above.

PS:

The grayed "Send 16-bit Data" is documented in my first screen shot (post #1) so it was not my imagination, though it seems to be functiong now.

EPSON BORDERLESS PRINTING ZOOMING IN CLIPPING IMAGE

i am posting this in case anyone gets stumped with how Epson appears to have changed its Roll Paper - Borderless (Auto Expand) behavior — it is zooming in too much and severely clipping my image

i am not sure where/when it changed, but i just went back to 10.4.11/CS4 and it printed correctly as i always have

Epson Advanced Product Support (Long Beach) pointed me to File> Print> Print Settings> Roll Paper Settings> Borderless Enlargement Setting (set to "Min" returns the zoom ratio to what i see in my 10.4/CS4 print, except i have a hairline white border along one side of the 10.7/CS6 print)

my settings for 24x30 borderless print on 24" Epson 7880 printer

Photoshop douument width: 23.8x29.75"

Epson Custom Print Size: 24x30"
