Isso tudo me lembra quando eu participava no FISL, não me lembro exatamente, pode ser em 2003 e 2004, e eu dei tutoriais sobre CUPS em Português, com a sala superlotada, pessoal assistindo em pé, os organizadores me daram 3 PCs (cada um com monitor CRT) e 2 impressoras para demonstrações de impressão em rede ...
Em um destes 2 anos tinha também Jon Maddog Hall lá ...
E tinha churrascos deliciosos ...

Oh, so that's why my dad was telling me he was unable to print anything lately… https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/issues/201#note_2686686

@kkremitzki @concretedog I have invited the creators of the #OpenPrinter to our booth, but as the license for their published construction plans was a CC license with "non-commercial" restriction, the licens was non-free and so #FOSDEM organizers have not accepted them.
The creators plan to open up their license once their printer is in production, so perhaps next year you will see it on FOSDEM ...

@BrodieOnLinux made some nice video about the problems of funding infrastructure FOSS projects which nobody sees, mainly with the libxml2 example, but OpenPrinting is appearing twice, too:

I am already in contact with the authors and support them from the software side. The software of the main controller board will be most probably PAPPL and libcups 3.x, making the printer appearing as a modern, driverless printer, both via network and via USB.
You can participate in the discussion via Discord, see link on

We at OpenPrinting are aware of the problem and the bug is actually in CUPS and not in GNOME/GTK.
See
https://github.com/OpenPrinting/cups/issues/176
I have originally reported this one. See the answers of CUPS author Michael Sweet. He has developed primarily under Mac OS (BSD-based) which uses mdnsresponder (Not Avahi as in Linux) where the problem does not occur, seems in CUPS' Avahi support.
Set as milestone for first CUPS 2.5.x release.

FOSDEM has selected the booths for 2026 (Jan 31-Feb 1, Brussels). And our joint booth of OpenPrinting and OpenPrinter is accepted!
I will, together with Akarshan Kapoor, Léonard Hartmann, Laurent Berthuel, Nicolas Schurando show everything about printing with FOSS, and we will have ...
... a repairable, sustainable printer!
And we welcome everybody who wants to join the OpenPrinting community

@gael You started early, in i386 times, Linux' first architecture. When I started in 1997 with SUSE 5.1 we had mostly Pentium and some i486, 8MB and 16MB RAM, FVWM, built KDE 1.0 first time in 1998 (?) (on SGI IRIX), installed Mandrake Linux for the first time on my first laptop mid-1999, and on my wife's PC in April 2000, got invited to work at MandrakeSoft to switch the distro to CUPS min-2000.
So you did an important step to what I am now. Thanks!

Finally I succeeded to get my report out.

For the Python programmers under you who wanted to make your app print, you probably have used pyCUPS to talk with the printing system. Perhaps you have also seen that it is not well maintained, not keeping pace with new APIs. Problem was its design, being a maintenance nightmare.
But for libcups3 it gets much better, thanks to the most Pythonic GSoC contributor we ever had, and CFFI:

One of my best GSoC contributors for OpenPrinting was Akarshan Kapoor. He worked on scanning support in PAPPL (Scanner Applications, emulation of driverless scanner as easily portable and packagable scanner driver format). He also had an internship about Zephyr/IoT in Germany.
See the summary in the video he produced for UbuCon Asia 2025:

@martinsteiger @rapha3l No drivers at all! The operating systems just support the driverless #IPP standards, without explicit support of these printer models.
The printers are certified to fulfill the AirPrint, Mopria, and/or IPP Everywhere standards by being run through test programs, and therefore they are in the list.
-
A well-maintained list of driverless #IPP printers (#AirPrint, #Mopria, #IPPEverywhere) you find on the OpenPrinting site:
https://openprinting.github.io/printers/
Michael Sweet, author of CUPS, is continuously updating it.
-
🧵 ...
But your work, as done in #Go will be very helpful for Go developers to integrate scanning, especially as I am working on replacing #SANE by Scanner Applications, which are software emulations of #AirScan (driverless) scanners, and so your Go code can make scan frontends written in Go use any scanner.
-
@zekjur @rapha3l Thanks a lot for implementing #AirScan #eSCL support in #Go.
In general, there are already 2 #SANE backends available for AirScan: "escl" in the standard sane-backends package and "airscan" in a separate repo, the latter also supporting WSD. These come in all major distros and provide AirScan support for all SANE frontends.

Usually anything related to setting up and configuring printers gets a bad rap, but recently, the SecureDrop Workstation moved to a "just-works" printing approach.

The #LinuxFoundation will mentor 21 contributors in the Google Summer of Code 2025!! #GSoC
Despite having lined up many more proposals than last year we got the same amount of slots.
11 for #OpenPrinting, 3 for #AGL (Automotive Grade Linux, 2 for each of #SPDX and #IIO (Industrial I/O), and 1 for each of #SOF (Sound Open Firmware), #Zephyr, and #KWorkflow.
See Google's announcements of the projects:
https://summerofcode.withgoogle.com/programs/2025/organizations/the-linux-foundation
-
Now it is done: At #OpenPrinting we have now full #RISCV support by our 6 Snaps in the Snap Store:
https://snapcraft.io/publisher/openprinting
- CUPS: Full printing stack
- ipp-usb: IPP-over-USB daemon for driverless USB printing
- 4 Printer Applications: All printer drivers which typically come with Linux distros, ~10000 legacy printers supportedThese Snaps can be used on the the #DeepComputing Risc-V board for @frameworkcomputer laptops, also with #Ubuntu Core and #UbuntuCoreDesktop.
