Attendees
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
- Updates
- On ippusbxd Till also did some small changes (bug fixes and ease of use, especially
one can now start ippusbxd without command line arguments at all when there is only
one printer connected, the printer is on localhost:60000)
- readme.md: Tell that the Avahi patch was also tested on version 0.7.
- Use URF info in the USB device ID for the DNS-SD record.
- Use port 60000 (and following) as default port.
- Fix automatic search of an IPP-over-USB printer.
- Minor bug fixes.
- Avahi
- Still no answer from Trent Lloyd yet.
- 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.
- Lennart Poettering seems to be the maintainer.
- The systemd problem is solved now.
- Till updated to Ubuntu 18.04 (under development, release end of April 2018)
and the the problem was not there any more.
- What exactly solved the problem is not known.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/
- CUPS v2.3b3 Beta release on 1 February 2018 (Mike)
- More fixes for printing to old CUPS servers (Issue #5211)
- The IPP Everywhere PPD generator did not support deep grayscale or
8-bit per component AdobeRGB (Issue #5227)
- Additional changes for the scheduler to substitute default values for invalid
job attributes when running in "relaxed conformance" mode (Issue #5229)
- Localization changes (Issue #5232, rdar://37068158)
- The cupsCopyDestInfo function did not work with all print queues (Issue #5235)
- CUPS v2.3b2 Beta release on 17 January 2018 (Mike)
- Localization changes (Issue #5210)
- Build fixes (Issue #5217)
- IPP Everywhere PPDs were not localized to English (Issue #5205)
- The cupsGetDests and cupsEnumDests functions no longer filter out
local print services like IPP USB devices (Issue #5206)
- The cupsCopyDest function now correctly copies the is_default value
(Issue #5208)
- Printing to old CUPS servers has been fixed (Issue #5211)
- The ppdInstallableConflict tested too many constraints (Issue #5213)
- All HTTP field values can now be longer than HTTP_MAX_VALUE bytes
(Issue #5216)
- Added a USB quirk rule for Canon MP280 series printers (Issue #5221)
- The cupsRasterWritePixels function did not correctly swap bytes for
some formats (Issue #5225)
- Fixed an issue with mapping finishing options (rdar://34250727)
- The ppdLocalizeIPPReason function incorrectly returned a localized
version of "none" (rdar://36566269)
- The scheduler did not add ".local" to the default DNS-SD host name
when needed.
- CUPS Filters Summary (Till)
- Current release is 1.20.0.
- In this release cups-browsed supports using PPDs generated by CUPS (only for
queues which are based on temporary CUPS queues).
- Till has also overtaken all new functionality from CUPS PPD generator (support
for "mediacol-database", finishings, presets, ...), improved color space support
to make all color spaces of the printer accessible, and made all options and
choices in the PPD have human-readable strings, even strings for proprietary
items supplied by the printer.
- CUPS Filters v1.20.1 changes planned (Till)
- braille: Fix some missing options on indexv4. Thanks to
Samuel Thibault for this patch (Pull request #21).
- braille: Fix disabling margins on indexv4 in graphic
mode. Thanks to Samuel Thibault for this patch (Pull request #20).
- braille: Fix installation of brftopagedbrf. Thanks to Samuel
Thibault for this patch (Pull request #18, Issue #17).
- cups-browsed: Fixed crash when CUPS reports a print queue
without "device-uri" attribute when cups-browsed polls a
list of local CUPS queues (Issue #16).
- CUPS Filters v1.20.0 release on 29 January 2018 (Till)
- libcupsfilters: Let the PPD generator prefer the English
translation file from CUPS for the human-readable strings in
the PPD files.
- libcupsfilters: The PPD generator lists all page sizes with
human-readable names now, including proprietary names of the
printer.
- cups-browsed, driverless: Fixed get-printer-attributes call
on driverless printers for generating the PPD, explicitly
requesting the media-col-database attribute as otherwise
borderless page sizes do not appear.
- libcupsfilters: Fixed loading option/choice strings lists
from driverless printers for PPD file generation. Especially
proprietary media types appear correctly now.
- libcupsfilters: Completed color space support in the PPD
generator: Added DeviceGray/RGB/CMYK, default to 8-bit for
SRGB and to 16-bit for AdobeRGB, avoid duplicate listings of
the same color space.
- CUPS Filters v1.19.0 release on 15 January 2018 (Till)
- libcupsfilters: Let the PPD generator add the options "Print
Optimization", "Print Rendering Intent" and "Print Scaling"
if appropriate IPP attributes are found.
- libcupsfilters: Let the PPD generator read out the maximum
of info about color spaces and this way not only reliably
the correct choices are added to the ColorModel option but
also the maximum supported bit depth (8 or 16 bit) is used.
- libcupsfilters: Overtaken new features from CUPS PPD
generator: Presets, Finishing Templates, and extraction of
media sizes from "media-col-database"
- libcupsfilters: Improvements on header of generated PPDs:
use cups-filters version number, "drvless.ppd" PCFileName,
APSupplies and cupsChargeInfoURI from CUPS.
- libcupsfilters: Let the PPD generator use the IPP string
tables in the translation files of CUPS 2.3.x or newer
(English strings only). Let all options in the PPD have
human-readable option and choice names. In case of CUPS
2.2.x or older (or if the CUPS translation are missing) we
fall back to internal tables.
- 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.
- February 2018 - GSoC 2017 status
- Till has packaged cpdb-libs, cpdb-backend-cups, and cpdb-backend-gcp for Ubuntu
before Christmas. They are now approved as new packages in Ubuntu. Till has also
contacted the Ubuntu package maintainer of OpenOffice to inform him that he can
use Yash's change for the OpenOffice Package.
- Still no answer from Avahi's upstream maintainer about the Avahi patch for
localhost support. Ubuntu 18.04 will contain the patch as distribution-specific
patch.

- October - GSoC Mentor Summit at Google
- GSoC 2018 plan:
- The Linux Foundation is accepted as mentoring organization for GSoC 2018.
- We are now inviting mentors so that they can register and have access to the GSoC
dashboard for the Linux Foundation. So they will be able to see student
applications there and step up as a mentor for the student projects they would
like to mentor.
- Here is the GSoC 2018 page of the Linux Foundation:
https://wiki.linuxfoundation.org/gsoc/google-summer-code-2018
- Here is OpenPrinting's list of project ideas:
https://wiki.linuxfoundation.org/gsoc/google-summer-code-2018-openprinting-projects
- We have 16 project ideas now.
- We need to prioritize the ideas to make sure the most important ones get mentors
assigned and projects implemented by students.
- There are plenty of students but we need mentors, one per project we actually want
to do in GSoC 2018. So anyone volunteering as mentor is welcome.
- Olaf Meeuwissen from SANE is willing to help on the mentoring of the SANE module
for IPP Scanning project.
- But this is not a feasible GSoC 2018, because no vendor supports IPP Scan yet.
- Rithvik has come up for doing a project in the GSoC 2018. The project ideas he
is interested in are the SANE module for IPP scanning (not feasible in GSoC 2018)
and the secure connection for IPP over USB. Rithvik also says that he has an
8-week (30 hours/week) internship from May 14 on, but he will compensate by
starting early on a GSoC 2018 project starting on March 5.
