There is no output (running under sudo).

The module is not blacklisted, but it's not loaded either (I'm not in
an IPv6-enabled network).

There is only:
/etc/systemd/system/cups.socket.d/cupsd-listen.conf ->
../../../cups/cupsd-systemd-listen.conf
Contents:
[Socket]
# This file was generated by CUPS and _WILL_ be deleted or overwritten by it!
# It has to be kept in sync with the Port and Listen stanzas in
/etc/cups/cupsd.conf
# It is by default symlinked as cups-listen.conf in the
# /etc/systemd/system/cups.socket.d/ directory. Remove the symlink
# and write your own file there if you don't want this. See systemd.socket(5).
# Matches 'Listen localhost:631' from cupsd.conf
ListenStream=127.0.0.1:631
ListenStream=[::1]:631
# Matches 'Port 631' from cupsd.conf
ListenStream=0.0.0.0:631
ListenStream=[::]:631
> Could you also attach the output of `systemctl show cups.socket` ?
