For example.  I don't think it matters much whether they come after or
before the ses-cell calls.

It only defines this dynamically-bound variable as buffer-local.
The function is unaffected.

Elisp doesn't have buffer-local functions, indeed.

Actually, you don't need to use the symbol at all.
In ses-cell, just check if the printer's name is found in your hash-map
and if so, use the function you found there instead.

This way, the user can give local names without having to worry about
affecting other packages which might accidentally be using the
same names.
