Print profiles are normally installed when the printer is installed. These are indendepdant of LrC.
Could it be that you somehow lost those selected to appear in the pulled down? In Print, select Profile->Other under Color Management and see what's listed. If you don't see your printer profiles, I'd suggested reinstalling the printer.
The profiles are buried deep with the Epson driver package Some apps see them and others don't. Fortunately, there are a few workarounds for the later. The one I use is to make a copy of the profiles, then paste them into the ColorSync > Profles folder. However, the trick is to find them first.
In below screesnhot, you'll see that I have highlighted the path to the profile folder. In my case they're located in InkJetPrinter2, but yours will depend on how many Epson Inkjet printer drivers you have installed. When you find the correct printer folder you should open the ICCProfiles folder. Next right-mouse button click on the file and choose 'Show Package Contents' from context menu. Now copy the profiles to ColorSync > Profles folder. Lighttroom should now be able to find them.
That's weird @Ian Lyons . I've had both Epson 1400 and Epson 15000 printers and both have automatically copie the profiles to the Windows directory c:\windows\system32\spool\drivers\color. I also find my Canon printers there. Is this a MAX quirk?
