[Bug 1731417] Re: Installed network printer removed automatically when turned off

[Till Kamppeter]

I have now backported cups-filters 1.23.0 to Cosmic. To install it, go
to my PPA

https://launchpad.net/~till-kamppeter/+archive/ubuntu/ppa

Follow the instructions under "Adding this PPA to your system" and then
update your system. You will get the new cups-filters which contains my
changes. Note that this version of cups-filters requires an update of
QPDF which you will automatically get together with cups-filters.

Please tell whether this version solves your problem.

[Bug 1731417] Re: Installed network printer removed automatically when turned off

[Till Kamppeter]

The 1.23.0-1 version got uploaded to the development of 19.10 (Eoan).
For getting it into an already released Ubuntu version, a Stable Release
Update (SRU) would be needed. But note that if you are still using 18.10
(Cosmic), that in a few months (end-July) the support for Cosmic ends,
so SRUs for this version do not make much sense. So I recommend you to
upgrade to 19.04 (Disco) and try whether the problem still persists for
you and report back here.

cups-filters (1.23.0-1) experimental; urgency=medium

  * New upstream version 1.23.0
- cups-browsed: When removing a local queue on shutdown or
  when DNS-SD reports the printer as disappeared check whether
  the local queue got overwritten by an external process as
  sometimes the shutdown or disappearing event comes too close
  for cups-browsed receiving a printer-modified notification
  from CUPS before (LP: #1731417)

[Bug 1731417] Re: Installed network printer removed automatically when turned off

[Till Kamppeter]

According to the attached log files hp-setup has created a print queue
with the same name as a queue created by cups-browsed, overwriting this
queue. As cups-browsed removes all the queues it created when it shuts
down, it also has removed this queue.

Normally cups-browsed gets a notification from CUPS on any queue
modification and if one overwrites one of cups-browsed's queues, cups-
browsed releases the queue from its control and so it does not get
deleted on shutdown. Only here cups-browsed got shut down too quickly
after the queue got overwritten, leaving no time for cups-browsed to
receive the notification from CUPS and release the queue from its
control. Probably hp-setup restarts CUPS right after creating a queue
and this makes systemd restart cups-browsed.

To overcome this problem I have now added an additional check to cups-
browsed that if it removes a print queue, independent on whether on
shutdown or when a printer disappears from DNS-SD (printer turned off or
so), it checks whether it perhaps got overwritten and refrains from
removing in such a case.

I have committed the fix to the upstream GIT of cups-filters:

https://github.com/OpenPrinting/cups-filters/commit/4814a2238

If you are familiar with building software from source, please test.

[Bug 1731417] Re: Installed network printer removed automatically when turned off

[Launchpad Bug Tracker]

This bug was fixed in the package cups-filters - 1.20.2-0ubuntu1

---
cups-filters (1.20.2-0ubuntu1) bionic; urgency=medium

  * New upstream bug fix release
- cups-browsed: If the user modifies/overwrites a print queue
  created by cups-browsed, it will now automatically released
  from the control of cups-browsed, so the modified queue does
  not get removed by cups-browsed on shutdown. (LP: #1731417).
- cups-browsed: The configuration setting
  "CreateIPPPrinterQueues LocalOnly" suppressed also the
  automatic generation of local queues for remote CUPS
  printers whereas this option is only intended for physical
  IPP printers.
- cups-browsed: Identify remote CUPS queues by the
  "printer-type" TXT record entry and not by the
  "ipp(s):///printers/" URIs, there are also IPP
  network printers with such URIs (HP LaserJet Professional
  M1212nf MFP in LP: #1731417).
- .gitignore: Added filter/braille/filters/brftopagedbrf
- cups-browsed, foomatic-rip: Fixed several typos. Thanks to
  Didier Raboud for the patches.
  * Removed all patches with got merged upstream.

Thank you very much for all the files. With this I could fix two bugs in

Fixed version on the way to Bionic.

[Bug 1731417] Re: Installed network printer removed automatically when turned off

[Till Kamppeter]

Please doi the following:

Make sure Bonjour is active in your printer and in your computer. With
the printer turned on run the command

avahi-browse -v -t -r -a > avahi.txt 2>&1

again. Look into the avahi.txt file and check whether it contains
entries from your printer. If not, keep the printer turned on and
Bonjour active in both the printer and computer and run the command
again later. Check again, does the avahi.txt contain entries for your
printer now? If yes attach the file to this bug report.

If you still get no entry of your printer into the file, turn off and
turn on the printer again. When the printer has started up, run the
command again. Does the fiule contain an entry of the printer now? If
so, attach the file to this bug report.

I can also confirm that if I disable bonjour, the printer no longer gets
removed once it's turned off
