How can I do this? My separations button is grayed out and there is no "output" button at the top.
What are you trying to do exactly in Photoshop?
I understand a bit what you are saying, but information like your version of Windows or MacOS and your version of Photoshop would help for starters.
As for printing to a commercial press,usually the print shop handles separations and would just want a file. Have you discussed with your printer what exactly they want?
Could you please reply via the browser?

Sorry, I've been fighting with this stuff a couple of days.
I have tried to reply via the browser and I had no reply button. Finally used Chrome instead of Explorer and there it is. What a mess, as the following may explain.
I AM the printer, and I've always made my own seps. Last week I had to upgrade my Illustrator version, which required me to go to the Adobe Cloud subscription. After doing that, I had to upgrade my computer because the new version of Illustrator is not compatible with Vista. That left me with Windows 8, which made my photoshop version obsolete. After going to the CC version of photoshop, I found that I could no longer make my separations from that program! Anyway, I was able to install a dummy printer, with postscript 3, and am now able to use Illustrator to make my seps, so I don't really need Photoshop for that anymore. I hope that explains the dilemma I was in, thanks!
Congrats on figuring it out yourself!
(I’m afraid I would not have been able to help you anyway.)
