Agenda
- Progress report
- Thursday, October 14, 2021, is Ubuntu release day again! Ubuntu 21.10!
- Not a lot of new stuff in terms of printing (in addition to all printing- and scanning-
related packages being up-to-date) but at least some nice things:
- The GTK print dialog finally lists virtual/temporary queues which CUPS generates for
driverless IPP printers and Printer Applications. So if one uses only GTK-based
applications, one does not need cups-browsed any more. But for now Till continues
providing cups-browsed, to support the Qt’s print dialog.
- libcups is patched with the same algorithm for mapping standard IPP attributes to PPD
option settings as Till has created in libppd in cups-filters for the Printer
Applications. So you can print to shared CUPS queues from your phone or IoT device and
easily get the printout as you like it.
- And there will be a virtual release party on YouTube!
- Progress report
- Our micro-conference on Linux Plumbers 2021 was a success! We discussed a lot on our
development plans. Especially Michael Sweet presented his plans on how to go on with the
CUPS development and the next releases. See the CUPS sessions below, Bhavna Kosta
presented her GSoC work on scanning with PAPPL.
- Watch the recording on YouTube.

- Progress report
- On last week's episode of the Ubuntu Office Hours we have talked about our success with the
Google Summer of Code (see also the announcement here last month). Not only Till and Aveek
were in the virtual studio but also two of our GSoC 2021 students, Divyasheel Printer
management GUI) and Pranshu Kharkwal (Universal CUPS filter).
- Our conversation with host Monica Ayhens-Madon about why and how we are doing GSoC, finding
students, introducing them to our projects, getting them as developer community members.
The students also told about their experience with us. We all have also given some tips to
everyone who wants to participate in the GSoC, as student, mentor, or organization, and in
the end we answered some spectator questions from the Live Chat.
- Thanks a lot to Monica Ayhens-Madon for inviting us!
- Progress report
- As Michael Sweet and Till talked about the New Architecture (Driverless IPP, Printer
Applications, RIP PPD files, ...) in the Ubuntu Indaba in August and Till also mentioned
that the printer setup tools need to change for this, the host; Heather Ellsworth from
Canonical, brought Till together with Frederik Feichtmeier, who is writing a replacement
for the GNOME Control Center completely in the Dart programming language with the Flutter
GUI toolkit (see link above).
- Frederik showed much interest in making the printing part of his tool to work with the New
Architecture. Till introduced Frederik to everything, giving him links to OP news posts,
our GitHub, the slides and video of the Linux Plumbers conferences, the Indaba, the Office
Hours.
- Frederik's tool is a good candidate to soon get a printer management tool of the new
generation.
- Thanks a lot to Heather Ellsworth for this contact!
- Progress report - 600 printers certified for IPP Everywhere v1.0 - 152 printers certified for IPP Everywhere v1.1
- Progress report - No update
- Progress report
- ipp-usb is also available as a Snap in the Snap Store now (229 downloads in the first 2
weeks)!
- So making use of IPP-over-USB for easy driverless printing and scanning on USB-connected
devices, one only needs to install the Snap and connect the printer to USB. You get an
emulation of an IPP network printer and CUPS and SANE find it automatically.
- The Snap also offers configurability, logging, and user-editable quirks as a classic
installation.
- Note that the Snap is usually not needed on Linux distribution which have ipp-usb already
installed and in working condition. Only if you have problems with the installed ipp-usb or
simply want to always have the newest version, install this Snap then. Make sure to
uninstall the system's ipp-usb (and also the obsolete ippusbxd).
- The challenge of making this Snap was to trigger ipp-usb on the appearing (and also the
presence) of IPP-over-USB devices.
- In the classic installation of ipp-usb (via make install or RPM/DEB package installation) a
UDEV rules file and a systemd service file (in systemd-udev/) are installed, so that the
system automatically triggers the launch of ipp-usb when an appropriate device is connected
or already present. A Snap is not able to do so. It cannot install any files into the
system. It can only bring its own, static file system and create files only in its own
state directory. These locations are not scanned for UDEV rules.
- So the Snap must discover the devices without its own UDEV rules, but it still can use
UDEV. The trick is to do a generic monitoring of UDEV events and filtering out the USB
devices with IPP-over-USB interface (7/1/4). If such a device appears, we trigger an
ipp-usb launch. We also check on startup of the Snap whether there is such a device already
and if so, we also trigger an ipp-usb launch.
- ipp-usb is run, as in the classic installation, with udev argument. This way it stops by
itself when there is no device any more (and we do not need to observe the disappearance
events of the devices) and it is assured that only one single instance of ipp-usb is
running.
- To do this with low coding effort, Till uses the UDEV command line tool udevadm in a shell
script (snap/local/run-ipp-usb in the source repository). Once it runs in monitor mode to
observe the UDEV events. Then we parse the output lines to only consider the ones for a
device appearing and run udevadm info -q property on each device path, to get the
properties and filter the 7/1/4 interface. In the beginning we use udevadm trigger in
dry-run mode to find the already passed appearal event of a device which is already
present. So the shell script is an auxiliary daemon to start ipp-usb when needed.
- We use the same method in the HPLIP Printer Application to automatically load firmware
files into USB devices.
- See also the README.md file and the "How to add or workaround a udev rule" thread on the
snapcraft.io forum.
- Till came to this idea with udevadm monitor by himself, but Oliver Grawert ("ogra" in the
snacraft.io thread) came to the same idea earlier. Till only became aware of it by Oliver
reacting to this thread.
- Progress report - No update
- Progress report
- Current PAPPL release is v1.2b1 on 24 September 2021.
- 8 commits to master since this release.
- The second beta release of PAPPL v1.1 is now available for download. PAPPL v1.1 adds
support for Wi-Fi configuration, IPP-USB, printer driver lookup and auto-add functionality,
improves management of multiple printers, and adds support for Microsoft Windows 10 and
higher.
- Changes in 1.1b2 include:
- Added support for papplDeviceGetID with network devices (Issue #95)
- Added support for the "compression" option.
- Added English names for Tabloid and A3 media sizes in the web interface.
- Added "server-hostname" and "listen-hostname" server options to the default mainloop
system callback.
- Fixed support for default printers, added indicator in web interface (Issue #182)
- Fixed support for printers with spaces in their names.
- Fixed the "jobs" subcommand.
- Fixed support for page-ranges.
- Fixed support for printers that do PDF beyond converting it to raster.
- Fixed support for mainloop subcommands on Windows.
- Fixed error message when Bonjour for Windows is not installed.
- Progress report - No update
- Progress report
- On all four currently available retro-fitting Printer Applications, PostScript,
Ghostscript, HPLIP, and Gutenprint, the following improvements were done:
- No log rotation: As PAPPL rotates already after a rather small portion of log, we decided
to de-activate PAPPL's log rotation completely in the Snaps. To avoid filling up the
disk, the default log level is "Error" (this can be changed in the web interface of the
Printer Application).
- Maximum of 256 instead 32 vendor-specific options in PAPPL: As the Snaps of the Printer
Applications build PAPPL by themselves, Till has patched the hard-coded maximum for the
number of vendor-specific options in PAPPL (a single number) as many PPD files
(especially Gutenprint but also some high-end PostScript printers) have more options.
This assures that always all options get available. See also our discussion on the
Gutenprint mailing list.
- Use CUPS' backends and not PAPPL's: This gives the following improvements:
- Quirk workarounds for USB printers with compatibility problems are used. The quirk
rules can be edited or new rule files added in /var/snap/*-printer-app/common/usb/
- Additional network protocols: IPP, IPPS, LPD. Especially one can send PostScript output
to the printer via encrypted IPPS.
- The SNMP discovery can be configured via /var/snap/*-printer-app/common/cups/snmp.conf
- Stop building libjpeg9 in the Snaps: The libjpeg8 from Ubuntu Core 20 works well enough
and the Snap Store's build servers have difficulties to load the upstream source tarball
from the original web site, requiring triggering several rebuilds manually until the Snap
gets into the Snap Store. The libjpeg9 build was overtaken from the hp-printer-app Snap
(where it also had been removed later).
- Till has also posted a request for the Snap Store allowing auto-connections of all
interfaces of the Printer Application Snaps and it got approved. So the Snaps can get
easily installed from the Snap Store.
- Progress report
- To help users to find the correct drivers for their printers we always had the OpenPrinting
printer/driver compatibility database. Now, as most of the legacy drivers listed there are
in one of the four retro-fitting Printer Applications, we now have links to the appropriate
Printer Application in each of the driver entries of drivers which are contained in one of
the Printer Applications. So now people can finally install the desired driver on
practically any Linux distribution (HPLIP, Gutenprint, pxlcolor, hl7x0, Ricoh PostScript).
- Progress report
- Gutenprint Printer Application in the Snap Store, 520 installations via Snap Store
- One of the most important printer driver suites in free software has made it into a Printer
Application (and also into the Snap Store) now. It is known for its high output quality,
adjustability, and support for third-party papers and ink sets. Now one can easily install
its newest version on nearly any Linux distribution and easyily print from any IPP-capable
device (like phones) but adjust all its options via web interface.
- Gutenprint supports more than 3000 different printer models, especially inkjet printers
from Epson and Canon, dye-sublimation photo printers, PCL 4/5c/e laser printers, but also
some other printers. In addition it provides generic support for the different PCL flavors,
everything which is supported by the Gutenprint CUPS Raster driver. Some of these printers
are probably also driverless IPP printers, but you can still use this Printer Application
then as perhaps you could get better output quality.
- The challenge when encapsulating this driver in a PAPPL-based Printer Application was that
some PPDs (higher-end Epson inkjets) have around 120 options whereas PAPPL only supports 32
vendor-specific options by a hard-coded array. Fortunately, one only needs to change one
number in PAPPL's source code to change this limit. So at least in Snaps, which build their
own copy of PAPPL one can adjust the limit. So in all retro-fitting Printer Application
Snaps, Till changed it to 256. It is more a problem in distribution packages, where the
PAPPL package is not modified. Here the Printer Application automatically switches to the
simplified PPDs of Gutenprint.
- Another point which could cause problems are the high resolutions (uo to 5760x2880 dpi)
which the driver uses. If we let the Printer Application simply use these, this can make
clients (those which send jobs in Apple Raster or PWG Raster) render their jobs in such
extreme resolutions and slow down the devices, slow down the printing and the data
transfer, or even crash the client device. Therefore we limit now all retro-fitting Printer
Applications to 1440 dpi for high, 720 dpi for normal, and 360 dpi for draft quality. 1440
dpi is good enough for fine drawings and 720 dpi good enough for photos. The higher
resolutions are used only internally now, for the driver to use a sophisticated,
fine-grained dithering.
- Both of these issues were discussed on the Gutenprint mailing list (free-of-charge
subscription required to discuss on the list).
- Progress report
- HPLIP Printer Application in the Snap Store, 1316 installations via Snap Store
- The HPLIP Printer Application experienced two substantial changes during the last month:
The Snap uses the source code of the Debian package and not the upstream one and the
Printer Application supports installing the proprietary plugin via web interface now, also
in the Snap.
- Source code from Debian
- HPLIP's original source, as it comes from HP’s web site has many bugs, unfortunately.
The HPLIP developer team has a bug tracker at Launchpad and the bugs got reported there
but it seems that the developers are not reviewing and merging the proposed patches.
- Therefore the Debian package of HPLIP (which is also used by Ubuntu) has 81 patches,
partially originating from the Debian and Ubuntu developers but also from RedHat/Fedora
developers.
- As it would be a lot of work to add the patches to the HPLIP Printer Application
repository to be used in the Snap build, we have simply switched to Debian's GitLab
repository as source instead of the original upstream tarball, as on Debian's repository
the patches are already applied.
- This way in the HPLIP Printer Application Snap all these bugs are fixed and thanks to
Debian's re-packaging of the original source, the code is totally free software (HP's
original code contains a closed-source library even without the proprietary plugin).
- Support for the proprietary plugin
- Unfortunately, HP has some (cheaper) laser printers which do not work with totally free
software. They either need their firmware loaded everytime when they are turned on or
they need a closed-source driver for their proprietary print data format. For this HP has
issued a proprietary plugin which joins all these extensions for all devices needing it
in a single package. On a classic HPLIP installation (as it usually comes with Linux
distributions) one can install the plufin with the hp-plugin utility, or when setting up
the printer with hp-setup.
- Now the plugin can also be used with the HPLIP Printer Application Snap. In the web
interface (see screen shots in the Snap Store), on the front page, under "Other Settings"
there is an "Install Proprietary Plugin" button now (and at the entries of all printers
which need the plugin is a "Plugin" button). Clicking one of these leads to a web
interface for installing the plugin, and also for updating, removing, and re-installing.
One needs only to click the appropriate buttons, accept the license (on initial install)
and the plugin gets installed.
- Once the plugin in place, the USB is observed (as with ipp-usb above, as we cannot
install UDEV rules out of a Snap) to upload the appropriate firmware file if a USB
printer which needs it appears (or is already there when starting the Snap).
- If the Snap gets updated by one with a newer HPLIP version, the plugin gets updated
automatically.
- When installing the HPLIP Printer Application classically one can also install the plugin
via web interface, but only if the Printer Application is running as root. Automatic
updates of the plugin only happen when (re-)starting the Printer Application, also only
as root. Running as non-root the web interface page only shows the status of the plugin,
and the user has to install with ho-plugin of the (then also classically installed)
HPLIP.
- As scanning support in PAPPL is not ready yet, scanning on multi-function printers is not
yet supported.
- Progress report - No additional update.
- Progress report - No additional update.
- Progress report
- CUPS Snap in the Snap Store, 2832 installations via Snap Store
- Till is still waiting for the snapd team to implement the security concept on the snapd
side, but unfortunately, they are very busy currently but the merging into snapd is
expected still in October, so that for the full developemnt cycle of Ubuntu 22.04 LTS
(J.J.), starting end of October, it will be available for testing and deciding whether said
Ubuntu version will come with the CUPS Snap as standard printing environment, and naturally
uploading of applications which print into the Snap Store will get easy and fully
automatic, without any manual review and permission needs.
- Michael Sweet has done some clean-up on the Snap support of CUPS and Till has tested it
with the CUPS Snap. All is working correctly.
- Main TODOs are:
- Complete the security concept on the snapd side, especially implement the content
interfaces (see above)
- Testing
- Turn classic CUPS drivers into Printer Applications (see progress above)
- Add a migration script so that OS distributions can easily switch over from classic
packages to the CUPS Snap
- CUPS (Mike)
- Current release is OP CUPS v2.3.3op2 on 1 February 2021.
- 404 commits to master since this release.
- Development of CUPS 2.4 is in progress, currently mainly fixing of bugs which were reported
to Apple's CUPS GitHub in the last 20 months.
- Ubuntu Impish Indri (21.10, release Thursday, 14 October 2021) will also come with CUPS
2.3.3op2, the CUPS Snap and our CUPS-driver-retro-fitting Printer Application Snaps use the
current GIT master.
- As outcome of our OpenPrinting Micro-Conference on the Linux Plumbers 2021 on 20 September
2021 (see Michael Sweet's slides) we will proceed with the development of CUPS as follows:
- CUPS 2.4
- Feature highlights:
- Official AirPrint/Mopria printer sharing support
- OAuth support
- Explicit container support (Snap for now)
- pkg-config support
- Deprecated cups-config and Kerberos (will be removed in 3.0, replaced by OAuth)
- Release schedule:
- Beta in the end of September 2021
- Release Candidate in October 2021
- 2.4.0 in November 2021
- Patch releases every 2 months from January 2022 on 2.4.1 or 2.4.2 in Ubuntu 22.04 LTS
- Release Manager: Most probably Zdenek Dohnal (RedHat)
- CUPS 2.5
- Feature highlights:
- OAuth support in cupsd
- OAuth callback for desktop - D-BUS API - Good for containers to do it with DBUS-API
TLS/X.509 improvements
- Centralized localization - OSes usually have their own localization services
- Other container technologies - Docker, AppImage, Flatpak
- Release schedule:
- Beta in the end of September 2022
- Release Candidate in October 2022
- 2.5.0 in November 2022
- Patch releases every 2 months from January 2023 on 2.5.1 or 2.5.2 in Ubuntu 23.04
- Release Manager: Most probably me (Till Kamppeter)
- 2.5.x is probably the last 2.x.
- CUPS 3.0
- Feature highlights:
- 100% free of PPDs!
- New architecture of separate modules:
- Command line utilities: lp, lpstat, lpadmin, lpinfo, ...
- Local server: Runs as normal user, only temporary/virtual (auto-generated queues)
pointing to IPP printers/Printer Applications, spooling filtering, only on domain
sockets, D-Bus (protocol similar to CPDB backend, merge with it?)
- Sharing server: Runs as root, only permanent queues, web interface, network,
accounting
- CUPS library, to be used by all the components above
- Release schedule (development together with 2.5):
- Beta in March 2023
- 3.0.0 in October 2023
- Ubuntu 24.04 LTS to be the first PPD-free Ubuntu!
- CUPS v2.4-b1 planned changes (Mike)
- Added basic OAuth 2.0 client support (Issue #100)
- Now show better error messages when a driver interface program fails to provide a PPD
file (Issue #148)
- Added dark mode support to the CUPS web interface (Issue #152)
- Fixed an interaction between `--remote-admin` and `--remote-any` for the 'cupsctl'
command (Issue #158)
- Fixed some IPP Everywhere option mapping problems (Issue #238)
- Fixed support for "job-hold-until" with the Restart-Job operation (Issue #250)
- Fixed the default color/grayscale presets for IPP Everywhere PPDs (Issue #262)
- Fixed support for the 'offline-report' state for all USB backends (Issue #264)
- Web interface updates (Issue #218)
- Fixed several Windows TLS and hashing issues.
- Removed support for the (long deprecated and unused) 'ListenBackLog directive in
'cupsd.conf' and 'cups-files.conf'.
- CUPS Filters Summary (Till)
- Current release is v1.28.10 on 17 August 2021
- Current development work is finishing up, testing, debugging this year's GSoC student
projects, improving and optimizing the rules for mapping job IPP attributes to PPD option
settings, and smaller feature needs appearing during the CUPD driver retro-fitting work
(but most is already done for this). Now we also need to clean up and sort out things to be
able to do a first 2.x release of cups-filters.
- Merged Pratyush Ranjan’s Pull Request for converting the texttotext CUPS filter into a
filter function. Now the filter function conversion work is completed!
- Make cupsRasterParseIPPOptions() work correctly together with printers with PPDs,
especially to not mis-interprete the weird "Resolution" variant choice names of
Gutenprint (like "301x300dpi").
- Change "Eastmak Kodak Company" to "Kodak".
- In IPP-attributes-to-PPD-options auto mapper rules considering "ColorMode" also with
prefix (like "cupsColorMode") now.
- Fixed PPD URIs when generating dynamic PPDs, so that they do not depend on the absolute
path of the dyanamic PPD generator.
- Deal with too large custom page size limits in PPD files when creating PPD cache
- Also several minor bug fixes were done.
- Michael Sweet's PDF file handling library PDFio is a good candidate to replace QPDF in
cups-filters, to eliminate the need of C++ and therefore make the code easier to maintain.
- Till discussed this with Michael on the Linux Plumbers and we discovered that two important
features were missing and he suggested that Till should post feature requests:
- Generate streaming output (vs. file output) (Feature requst, already implemented)
- Flattening filled interactive PDF forms and annotations in PDF files to get a static PPD
file with fields filled (Feature requst, Michael is investigating)
- Ubuntu Impish Indri (21.10) will come with cups-filters v1.28.10. The CUPS Snap currently
uses v1.28.10. The Printer Application Snaps use the current GIT master of cups-filters.
- CUPS Filters release v2.0.0 planned changes (Till)
- libcupsfilters: Make cupsRasterParseIPPOptions() work correctly together with PPDs, by not
parsing options which are in the printer's PPD and using ppdRasterInterpretPPD() when
set_defaults = 1 is set. Without PPD the function behaves as before.
- libcupsfilters: Let the ieee1284NormalizeMakeAndModel() function clean up "Kodak"
manufacturer name, as it is sometimes reported as "Eastman Kodak Company".
- libcupsfilters, texttotext: Moved core functionality of texttotext into the texttotext()
filter function (Pull request #425).
- libcupsfilters: Let colord_get_profile_for_device_id() not return empty file name, to avoid
error messages in CUPS error_log.
- CUPS Filters release v1.28.11 planned changes (Till)
- libcupsfilters: Let colord_get_profile_for_device_id() not return empty file name, to avoid
error messages in CUPS error_log.
