No errors given.

Rebooted PC. and now Okular doesn't give a printer choice, only pdf output. Worked OK yesterday before update.

Confirmed, also with Okular in the build repo (23.03.90), rebuild does not show any missing or error, so no idea yet what is causing this. I have not checked printing options in Okular for a long time, so no idea when it started.
Only issue I see, when opening printer properties, there is a warning in red There are conflicts in some options. Please fix them.

Great Demm, you are ace. My systems have been running great for ages.

It is not just Okular, al Qt based applications fail to offer anything but print to file option, so probably an issue with Qt5 (and 6)-base being rebuild on new openssl, before cups was rebuild.

EDIT:
Yup, that was it, rebuild qt5-base fixes the issue. Thanks for reporting.
Rebuild will move shortly, in the meantime, get it with:

sudo pacman -U http://kaosx.tk/repo/build/qt5-base-5.15.8-5-x86_64.pkg.tar.zst
