Agenda
- We are moving to GitHub now: https://github.com/OpenPrinting - Till is already looking into using GitHub also for generating the front page for OpenPrinting and pages for the projects.
- Moved to new upstream home: https://github.com/OpenPrinting/ippusbxd - Updated readme.md with the complete Avahi patch for full localhost support.
- Avahi
- Till has requested the needed changes (including the one from Rithvik) on Avahi
in a bug report:
https://github.com/lathiat/avahi/issues/125
- The patch is posted as a Pull Request, so it is easy for the maintainer to
include. No answer at all yet. Maintainer Trent Lloyd seems to have disappeared.
- Till considers Avahi as unmaintained. Anyone wants to maintain it? Or knows
someone?
- systemd
- systemd also shows lack of maintainership. From Ubuntu 17.10 on USB printers
(auto-reported via UDEV) do not get auto-setup any more due to a problem with
systemd. This also affects auto-starting of ippusbxd when an IPP-over-USB
printer is connected.
- See:
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1721839
and
https://github.com/systemd/systemd/issues/7109
- Lennart Poettering seems to be the maintainer.
- As Avahi this is an important part of the system infrastructure. New
maintainer more than welcome.
- See GSoC 2017 status for more driverless printing details.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/

#5012)
- Bonjour printer sharing now uses the DNS-SD hostname (or ServerName
value if none is defined) when registering shared printers on the
network (Issue #5071)
- The ipptool command now supports writing ippserver attributes files
(Issue #5093)
- The lp and lpr commands now provide better error messages when the
default printer cannot be found (Issue #5096)
- The lpadmin command now provides a better error message when an
unsupported System V interface script is used (Issue #5111)

there were open client connections (Issue #5118)

control the minimum and maximum TLS versions that will be allowed,
respectively (Issue #5119)

- The cupsEnumDests function did not include options from the lpoptions
files (Issue #5144)

unavailable (Issue #5154)
- Added label markup to checkbox and radio button controls in the web
interface templates (Issue #5161)
- Fixed group validation on OpenBSD (Issue #5166)
- Improved IPP Everywhere media support, including a new
cupsAddDestMediaOptions function (Issue #5167)

- The scheduler now generates a strings file for localizing PPD options
(Issue #5194)
- CUPS Filters Summary (Till)
- Current release is 1.18.0.
- Clean-up and fixes in the build system and the pdftoopvp and pdftoijs filters
are deprecated now and only built if requested via ./configure command line.
With this it should be tested whether they are actually still used by someone.
If no one complains they will later get completely removed.
- Otherwise mainly improvements and fixes on the Braille embosser support
(Thanks, Samuel Thibault for your great work!) and also some fixes in
cups-browsed and gstoraster.
- CUPS Filters v1.19.0 changes planned (Till)
- cups-browsed: Improved debug output when checking IPP attributes of IPP
printers.
- .gitignore: Ignore also core files.
- cups-browsed: Support use of PPD files generated by CUPS for IPP Printers.
Works only if the the local queue created by cups-browsed replaces a temporary
queue from CUPS. Configurable via "UseCUPSGeneratedPPDs" directive in
cups-browsed.conf.
- CUPS Filters v1.18.0 release on 19 December 2017 (Till)
- braille: Add support for page-ranges option. Thanks to Samuel Thibault
for this patch (Pull request #12).
- braille: Fix supporting docx and LO file names with spaces. Thanks to Samuel
Thibault for this patch (Pull request #11).
- .gitignore: Updated and cleaned up.
- Build system: Make sure that "make dist" always includes all
files of the repository, plus the files generated by
./autogen.sh, independent of the system configuration and
the used ./configure options.
- pdftoijs, pdftoopvp: Build pdftoijs and pdftoopvp only on
demand (via "--enable-ijs" and "--enable-opvp" on the
./configure command line). There are actually no known
printer drivers using these filters. If no one complains
about the missing filters they will get completely removed.
- Build system: Set default path for pdftops to
/usr/bin/pdftops also for cross-compiling (Bug #1417).
- cups-browsed: Set "printer-location" as an attribute and not
as an option when creating/updating a CUPS queue (Bug #1413).
- braille: Fix handling non-printable characters in BRF
files. Thanks to Samuel Thibault for this patch.
- braille: Fix printing backslashes in BRF files. Thanks to
Samuel Thibault for this patch.
- braille: use application/vnd.cups-brf instead of
text/vnd.cups-brf. Thanks to Samuel Thibault for this patch.
- braille: Make sure liblouis emits pure BRF output. Thanks to
Samuel Thibault for this patch.
- braille: Spaces at the head of lines were not getting
embossed, because bash would eat them in the read
command. IFS allows to avoid the issue. Thanks to Samuel
Thibault for this patch.
- gstoraster: Emit proper error message if Ghostscript is
missing. Thanks to Peter De Wachter (pdewacht at gmail dot
com) for the patch (Bug #1415).
- braille: Old bash does not like quotes, like in '$(("123" +
0))'. Removed unneeded quotes. Thanks to Samuel Thibault for
this patch.
- braille: Index V5 embossers are compatible with the V4
protocol so we do not need driver changes, we just need to
advertise the support. Thanks to Samuel Thibault for this
patch.
- January 2018 GSoC 2017 status
- Till packaged cpdb-libs, cpdb-backend-cups, and cpdb-backend-gcp for Ubuntu
before Christmas. Now they are waiting for getting approved as new packages.
They are required for any of the print dialog improvements to make it into the
distro.
- Rithvik's patch for Avahi I have added to Ubuntu's Avahi package and also added
it to the upstream bug report. So it will in any case be in Ubuntu, to make sure
that IPP-over-USB is fully supported. Till did not get any answer from upstream.
Any help or volunteering for getting Avahi maintained upstream again is welcome.
- Rithvik has continued to work on the Qt print dialog, making sure that it uses the
correct libraries for upstream integration. He succeeded with this work in shorter
time than estimated. So we will not need to open another student project for this
in the GSoC 2018.
- GSoC 2018 Schedule
- 4 January to 23 January - Mentor organization applications
- 23 January - 11 February - GSoC reviews mentor organization applications
- 12 February - GSoC approves mentoring organizations

- 22 August - GSoC announces final results
- October - GSoC Mentor Summit at Google
- GSoC 2018 plan:
- We are using Aveek's very successful recruitment concept of starting
with finding students already in January again as we have been more
effective in finding good students.
- Aveek already got 100 CVs from students (now reviewing them).
- The time frame for the mentoring organizations to apply has started and Till has
already filled out all forms for the Linux Foundation. Till has also created
the GSoC 2018 web page for the Linux Foundation:
https://wiki.linuxfoundation.org/gsoc/google-summer-code-2018
- And our list of project ideas:
https://wiki.linuxfoundation.org/gsoc/
google-summer-code-2018-openprinting-projects
- We have 14 project ideas, the ones presented in our last OP meeting minutes,
some additional about IPP, and some left over ideas from last year.
- We need to prioritize the ideas to make sure the most important ones get
mentors assigned and get implemented by students.
- If we decide to remove project ideas from the list, we should do it only when
the Linux Foundation is finally accepted for the GSoC 2018, as the more ideas
are in the list, the more attractive we are for Google to accept us.
- There are plenty of students but we need mentors, one per project we actually
want to do in the GSoC. So anyone volunteering as mentor is welcome.
- Nilanjana got a job starting next summer and will not be available for the GSoC
2018.
