So first, please try to do as described in the question I linked (this
is the text from there but "translated" to CUPS):
-----
First check that the unit file is a symlink to /dev/null
file /lib/systemd/system/cups.service
it should return:
/lib/systemd/system/cups.service: symbolic link to /dev/null
in which case, delete it
sudo rm /lib/systemd/system/cups.service
Since you changed a unit file, you need to run this:
sudo systemctl daemon-reload
now check the status:
systemctl status cups
if it doesn't say loaded and running (if the circle is still red),
reinstall the package:
sudo apt-get install --reinstall cups-daemon
and reload the (systemd) daemon again
sudo systemctl daemon-reload
and check status once more
systemctl status cups
-----
It seems that "systemctl mask ..." eliminates a file installed from a
package completely from the system. Here you should report a bug on the
systemd package.
Once done the commands above you should have recovered your system to
what it was right after the update. You should reboot then and after
that check again whether you are in the original state (GNOME -> does
not correctly communicate with CUPS, non-GNOME -> all printing-related
works correctly) and then we need to investigate the GNOME issue.
