Agenda
- Progress report
- 26-31 July 2023 in Riga, Latvia
- From Till's July OP news.
- Till prepared everything for his 3 sessions, especially the slides, but also the exercises
and examples and a virtual machine image for the Snap workshop.
- See the schedules (above).
- Please also keep an eye on Mastodon for updates: #GUADEC2023, #GUADEC
* The New Printing GUIs: GNOME Control Center and Common Print Dialog Backends
Wednesday 26 July 2023
Right on the first day Till talked about the state of the art of the printing GUIs for the
New Architecture, the "Printers" part of the GNOME Control Center, and the Common Print
Dialog Backends (CPDB) support in the print dialogs and also gave a demo of the GUIs.
* Your app everywhere, just in a Snap! (Workshop)
Saturday 29 July 2023
This GUADEC got snappy! In this 2-hour interactive workshop you learned how to snap
(i.e., package as a Snap) your favourite applications! You snapped a simple GNOME
application on your own laptop and after that Till and Jesús Soto helped you to snap your
applications.
* GNOME/GTK Printing BoF
Sunday 30 July 2023
During his work on the New Architecture for printing and a recent discussion with GNOME
developers and designers, Till had 2 subjects that he wanted to discuss in-person:
1. UI Design for the GNOME Control Center "Printers" module with support for New Architecture
2. Separation of GTK printing API into its own project
Main participants of the discussion were Till, Matthias Clasen, and Jakub Steiner.
- See details in July OP News.
- Progress report
- 8-10 September 2023 at IIT in Mandi, India.
- Organizing every year the participation of the Linux Foundation as mentoring organization in
the Google Summer of Code (GSoC) and mentoring contributors for OpenPrinting Till works
together with Aveek Basu who joined OpenPrinting when he worked for Lexmark in India. Aveek
is reaching out to colleges and universities in India and this way we have every year around
5-7 students as contributors for OpenPrinting, most of them studying at the Indian Institute
of Technology (IIT) in Mandi.
- With the DebConf being in India, Aveek and me have decided to meet most of our current and
former contributors in-person and motivate the students, professors, and researchers to join
the community of developers, designers, doc writers, etc. in a 2-1/2-day conference, the
"Opportunity Open Source".
- We will:
- talk with our contributors about their GSoC experience on a panel
- have a GSoC Q&A session
- have the contributors presenting their work
- have talks about OpenPrinting
- have talks about Zephyr
- have Rudra Saraswat on the conference giving talks about his projects Ubuntu Unity and
blendOS
- have a panel and Q&A with Canonical employees telling about jobs at Canonical, how to
apply, how the work will be.
- have a talk (and perhaps also a workshop) about Snap by Till
- And for the attendees getting some real-life experience we are running this year's
OpenPrinting Roadmap Sprint (like our micro-conferences on Linux Plumbers: 2019, 2020, 2021,
2022) on the conference and attendees can participate in the discussion and planning of the
next 12 months in printing and scanning.
- We will also live-stream and record everything and allow remote participation.
- Progress report
- DebCamp 3-9 September 2023 (1st week)
- DebConf 10-17 September 2023 (2nd week)
- This year Till will be on Debian’s annual developer conference, DebConf, for the first time!
This year's edition will take place in Kochi, in the south of India.
- This is the annual 2-week meeting of the Debian developers to plan their work, first week of
DebCamp (informal, hackfest, BoFs) and second week of DebConf (talks, panels, workshops).
Till will attend the second week, starting from the 11th or 12th of September, depending on
when and how well he can arrive from Mandi.
- Till has submitted two presentations:
* The New Architecture for Printing and Scanning on Debian
With the DebConf taking place right in the new cycle after the Bookworm release, Till will
tell the Debian developer community about the New Architecture of printing and scanning to
help them switch the Debian distribution to the new IPP-only PPD-less realm. The talk will
also cover any news from our OP Roadmap Sprint in Mandi.
* Opportunity Open Source conference in the IIT Mandi, India: Motivating people to be a part
of us!
This talk is about how we have organized the conference, the challenges, and naturally also
the outcome and experiences with running it, having come right from there to the DebConf. And
we will have a Q&A session about organizing conferences and also being a mentoring
organization for the Google Summer of Code.
So everyone interested in running a free software conference and/or participating in the
Google Summer of Code is welcome to participate in this session.
- Progress report
- 5 of our 6 contributors have passed midterm. The 6th contributor did not fail, but we have
postponed his remaining part of the GSoC, including midterm.

- And Google does the Mentor Summits in-person again! So Till will be at this year's Mentor
Summit 13-15 October 2023 on the Google Campus in Sunnyvale, California! Till will meet his
fellow mentors from many different free software organizations to exchange experiences, tell
about the Opportunity Open Source in the IIT Mandi, and with Ubuntu 23.10 being released on
12 October 2023, celebrate the release!
- See details in July OP News.
- Progress report
- Now it finally happened! Ubuntu has switched over to use the CUPS Snap as its printing stack.
The Debian package of the CUPS daemon and of the classic CUPS drivers are going away.
- First, do not rush out to grab Ubuntu 23.10 (Mantic Minotaur) and install it for testing it
out, it has still too many rough edges in terms of printing. Especially do not install it on
your daily driver machine, as usual, you should not use a development branch for your daily
work...
- Till worked together with Sebastien Bacher, leader of the distro squad in the Canonical
Desktop Team. Sebastien told Till what is needed for the installation image inclusion
("seeding") of Till's Snaps and Till told him which Snaps have to get seeded and which Debian
packages removed, and finally Sebastien switched over and current daily ISOs now use the CUPS
Snap as their printing system.
- The Snaps being all migrated to core22 (Ubuntu 22.04 LTS) as base distro and all their
components updated to the newest upstream versions already last month, Till now had to give
them version numbers nad release all of them on the "stable" channel in the Snap Store.
- CUPS is already versioned, by the CUPS upstream version number plus a package release number,
similar to the (classic) packages of Linux distributions. The upstream version number is taken
from the metadata of the GIT snapshot of the CUPS upstream code loaded. The correct GIT
snapshot is selected via the release tag (source-tag: in snapcraft.yaml). This method is
already a preparation for future automation of updating the CUPS Snap triggered by a new
upstream release of CUPS via GutHub workflow.
- The 4 retro-fitting Printer Applications get their version numbers from their principal
component, plus a package release number:
- PostScript Printer Application: foomatic-db, current version 20230715-1
- Ghostscript Printer Application: Ghostscript, current version 10.01.2-1
- HPLIP Printer Application: HPLIP, current version 3.22.10-1
- Gutenprint Printer Application: Gutenprint, current version 5.3.4-1
- For all of them, Till selected the version via upstream release tags, so that later
automation will be easy.
- Now with all Snaps versioned, Till promoted the current versions of them into the "stable"
channel and, in addition, created ubuntu-23.10 branches for them in the Snap Store, as this
was needed for inclusion in Ubuntu 23.10.
- With this in place we could change the seeding in Ubuntu 23.10:
* Removed Debian (binary) packages:
cups-daemom
cups-browsed
cups-filters
ipp-usb
printer-driver-*
system-config-printer-*
* Added Snaps:
cups
ipp-usb
ps-printer-app
ghostscript-printer-app
hplip-printer-app
gutenprint-printer-app
- Note that the removal of the mentioned binary packages of CUPS does not eliminate the need of
the source Debian package "cups", as we still need the CUPS library, libcups2, of it.
Applications with print functionality installed classically, as Debian package, need this
library. Here things get improved with CUPS 3.x, as here the CUPS library comes as separate
upstream source.
- To be able to remove system-config-printer, Sebastien has updated the gnome-control-center
package, removing the patch which adds the button to start system-config-printer for advanced
configuration. system-config-printer is not actively developed any more and therefore did not
get updated to support the New Architecture.
