Agenda

(0) Google Summer of Code 2023 (Till)
https://opensource.googleblog.com/2022/11/get-ready-for-google-summer-of-code-2023.html
https://developers.google.com/open-source/gsoc/timeline
https://openprinting.github.io/OpenPrinting-News-January-2023/

- Progress report
- While still involved in the aftermath of GSoC 2022, having the contributors integrating
their work in the appropriate upstream projects, we are already preparing GSoC 2023. So we
are involved in the GSoC year-round.

- As the application period for mentoring organizations has already started (23 January 2023
to 7 February 2023), we have already lined up our project ideas (after some discussion with
Michael Sweet):

- Adding support for the new functionality/attributes of IPP Everywhere 2.x to
libcupsfilters and the Common Print Dialog Backends (CPDB)

- CPDB support for application's print dialogs: Firefox, Chromium, LibreOffice, ...

- Scanning support in PAPPL

- Turn cups-browsed into a Printer Application

- PAPPL-based Printer Applications: Option setting presets via web interface

- Make a native Printer Application from Gutenprint

- Continuous Integration (CI) Testing programs for libcupsfilters, libpappl-retrofit,
libppd, CPDB, ...

- GNOME Control Center: List and handle IPP print services for the New Architecture

- cups-filters: Create OCR filter to deliver scans as searchable PDFs

- Please contact us at any time if you are interested in being a GSoC contributor for
OpenPrinting on one of these projects or on another project idea of your own.

- We also have already many contributor candidates doing assignments: In stage 1, building
CUPS and cups-filters, learning about the code, the printing architecture, driverless
printing, etc. In stage 2, working on issues in cups-filters, CUPS, and other OpenPrinting
projects. And some contributor candidates already in stage 3, learning about the project in
which they want to do their GSoC 2023 work.

- The work on the GSoC 2022 projects and their integration continues and some are getting
continued in new GSoC 2023 projects.

- See January 2023 Open Printing News for more details.

(0) Linux App Summit 2023 (Till)
https://linuxappsummit.org/ (2023)
https://linuxappsummit.org/cfp/ (2023)
https://openprinting.github.io/OpenPrinting-News-Flash-OpenPrinting-and-Ubuntu-on-the-Linux-App-Summit-2022/

- Progress report
  - Probably you remember the great Linux App Summit 2022 in Rovereto, Italy. This year we 
    will have a Linux App Summit again, this time in Brno in the Czech Republic.

  - Brno is home of a Red Hat office and so many of our free software colleagues are located 
    there, especially those on GNOME. And they will be for sure on the LAS, making this year's 
    edition an awesome conference.

  - Update: LAS Call for Proposals is open right now!! Until 18 February 2023! Submit your 
    great, awesome, and interesting talks, lightning talks, BoFs, workshops...

  - Till will also be there again.

(0) New Architecture makes it into Ubuntu (and Debian) (Till)
https://openprinting.github.io/OpenPrinting-News-January-2023/

- Progress report
  - Now, with having a release (at least a beta) of all the important components: 
    libcupsfilters, libppd, cups-filters, cups-browsed, pappl, pappl-retrofit, cpdb-libs, 
    cpdb-backend-cups, cpdb-backend-file I have started to create Debian packages from 
    everything so that it gets into the Debian and Ubuntu distributions.

  - Unfortunately, Debian is currently entering the freeze for finalizing their Bookworm 
    release. So their developers are going from the add-new-packages-and-new-features into 
    the debugging phase.

  - But fortunately, Debian has at least finally accepted the Common Print Dialog Bsckends 
    (CPDB) components, cpdb-libs (ITP), cpdb-backend-cups (ITP), cpdb-backend-file (ITP) into 
    Debian unstable (after a reminder on their printing mailing list). The versions are still 
    1.x versions though, the latest stable ones on OpenPrinting, for the 2.x versions 
    libcupsfilters needs to get updated to 2.x first.

  - But the update to the second generation of cups-filters will only happen after Bookworm. 
    So all further packages and updates to their new generations will, if at all before the 
    Bookworm release, happen in Debian’s Experimental branch.

  - See January 2023 Open Printing News for more details.

(0) cups-filters bug fixes and second and third betas (Till)
https://openprinting.github.io/cups-filters-Second-Generation-Second-Beta-Release/
https://openprinting.github.io/cups-filters-Second-Generation-Third-Beta-Release/
https://openprinting.github.io/OpenPrinting-News-January-2023/

- Progress report
- During the selection and onboarding process for the GSoC 2023 (see above) we are assigning
many of our issues on GitHub to contributor candidates for them to learn about our code
base.

- This leads us to deeper investigation of several bugs and to fixes of them.

- As with this issue: To get the full capabilities of a driverless IPP printer, a Client
(CUPS, or the driverless utility) needs to poll "all" attributes *and* also the
media-col-database with a Get-Printer-Attributes IPP request (media-col-database is *not*
included in all responses by default, because it is often a very long list). Some printers
cannot cope with these two being polled in a single request. So Till added separate polling
of these two to work around this, and also added parsing of the media-col-ready attribute,
to lower chances to overlook something important (e.g., borderless printing support).

- Till needs to later on also add the separate polling of "all" and media-col-database to
CUPS.

- During packaging of the components in Debian packages, Till found and fixed some build
system and documentation bugs and also an API bug discovered during the CPDB work.

- After that, Till released the second beta (8 January 2023) and third beta (31 January
2023).

- In addition to documentation and build system fixes discovered during Debian packaging,
various other changes have been done.

- See January 2023 Open Printing News for more details.
