Any desktop environment? Let's see:
TDE? CUPS should be optional, barring bugs.
XFCE? Nope, no CUPS deps in the base environment (not even optional).
LXDE/LXQT? Same.
Mate? Same (granted, packages for it are a bit out-of-date in Gentoo)
Gnome? Needs a patch to make CUPS fully optional for gnome control center,
and there are a couple of other optional dependencies.
KDE? CUPS is required unconditionally by xdg-desktop-portal-kde.
So only KDE and Gnome could be said to require it, and Gnome is a bit
iffy.
Of course, Gentoo is not a binary distribution. With the package manager
compiling pretty much everything locally, I have a lot more freedom, at the cost
of slower installation times.
Interestingly, even gutenprint can be compiled without CUPS support, although
I'm not altogether sure why you'd want to.
