Yes there are many dependencies to libcups2, which presumably includes
all sorts of functions for interfacing cups. As you know, binaries
would typically build for accessing dynamic library functions already
for implementing the potential of using cups regardless of whether the
actual system actually provides those services.

For disarming libraries it may be better and sufficient to just move
away the actual ".so" file and let the package dependency management
believe it is installed. Possibly you should also add a "divert" for
that library file so as to avoid it be resurrected on updgrades;
though, as I haven't done much of that myself, I can't advice on the
specifics here. Maybe something like this
# dpkg-divert --add --local /usr/lib/x86_64-linux-gnu/libcups.so.2
