Hi,
I've tested cups-filters 1.8.3-2ubuntu3.2, but the problem (90 sec delay
on shutdown) remains.

Bug description:
I have updated to the latest cups-filters version to fix the bug as
described by bug report #1579905 but I still get that Ubuntu takes
very long to shutdown.
For now, I have simply disabled cups-browser and I manually start it
up every time I need to print something.
It is probably related to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=832637
as Till has described in #1579905. I tried to download and compile the
upstream version at BZR as suggested for Debian but I ended up not
being able to print anymore and instead went back to the current
version in the package distribution.
Hopefully, there is an easy fix for Ubuntu 16.04 as well.
[Impact]
On many machines the shutdown will take unusually long, typically the
90-second timeout after which a hanging process gets killed. One case
where this easily happens is if you have a remote CUPS server sharing
printers which your local cups-browsed picks up and your local CUPS is
not listening on localhost:631 (usually when it does not share
printers). cups-browsed also tries to access the local cupsd on
localhost:631 and hangs.
[Testcase]
Take two machines in one local network (can also be VMs), one being a
CUPS server with at least one print queue being shared, another a
client with CUPS and cups-browsed running but not sharing local queues
and not listening on localhost:631. It picks up the server's queues
but when trying to shut down cups-browsed, cups-browsed hangs. The
fixed package (cups-filters 1.8.3-2ubuntu3.2) solves this problem as
its cups-browsed shuts down correctly.
[Regression Potential]
The patch is not small, but it does only small and simple changes, not
replacing big bunches of code by other big bunches of code, so the
regression potential is rather low. The changes in the patch are also
all backported from the working upstream code of cups-filters.
