What operating system is your CUPS server? Does your server share its
printers?

What steps are you doing on your laptop? What are you doing after
opening the "Printers" application?

Is cups-browsed running on your laptop? Can you attach your /etc/cups
/cups-browsed.conf file?

Is avahi-daemon running on your laptop and on your CUPS server? Can you
attach the /etc/avahi/avahi-daemon.conf files?

Can you run the command

avahi-discover

in a terminal window on your laptop? Does it show a "_ipps._tcp" section
and/or an "Internet Printer" section? Do these section show the printers
of your server? Are these sections subsections of IPv4 or IPv6? Or are
they in both IPv4 and IPv6?

Please attach the requested files one by one, do not compress them and
do not package them together. Thanks.

Title:
  Printers app doesn't seem to do dns-sd

Status in “system-config-printer” package in Ubuntu:
  Incomplete

Bug description:
  I've just spent some time reconfiguring our DNS so that Macs could
  discover our CUPS print queues using dns-sd/bonjour

  I was surprised when I discovered this Ubuntu 14.04 laptop couldn't do
  the same thing. I have got a sniffer up watch all DNS traffic, and yet
  when I enter the "Printers" app to Add a printer, it shows no evidence
  of hanging whilst doing a scan, and certainly shows no DNS lookups for
  the standard PTR/SRV/TXT records used in dns-sd

  Is this supported by Ubuntu? I used to use Fedora and vaguely feel
  this worked in Gnome3?
