My friend asked Harman for the missing profile. Here is the answer:
Dear Mr Barrera,
When looking for profiles for the Epson 7900 please follow the 'PC' operating system route. This will give you a full selection of printers/media types including the FB AL products for the 7900. We are in the process of removing the operating system segregation from our website as it is no longer necessary with todays operating systems.
Please let me know if you have any further problems.
Kind regards,
Jon Webb

After all, it seems they are "universal".
Best
