Agenda
- We are moving to GitHub now: https://github.com/OpenPrinting - Here Till created the repositories for the new Common Print Dialog Backends (CPDB) project and moved over the ippusbxd and cups-filters project (converting it from BZR to GIT). - The other projects will follow. - As bug trackers we will use both GitHub's Issue Tracker and Bugzilla from the Linux Foundation in parallel (Till added the CPDB projects to Bugzilla), so that users can choose their preferred interface and one can overcome shortcomings of each of them by simply using the other.
- Moved to new upstream home:
https://github.com/OpenPrinting/ippusbxd
- Released 1.31 with some minor changes:
- Added missing 'TAG+="systemd"' to the UDV rules file
- Added support for the page description language PCLm in the DNS-SD
record
- Make DNS-SD advertising also working in the no-printer developer mode
- system-config-printer - no news - Avahi - Rithvik stepped up to volunteer on adding "localhost" support. - See GSoC 2017 status for more driverless printing details.
- CUPS source code and bug reports are handled on GitHub now

- CUPS Filters Summary (Till)
- October summary through release 17.1.9:
- Principal changes:
- Moved to new upstream home and converted to GIT:
https://github.com/OpenPrinting/cups-filters
- Tons of bug fixes for Braille embossers, around 20 patches from
Samuel Thibault.
- Fixes on error handling in foomatic-rip.
- Bug fixes in cups-browsed.
- September summary through release 17.1.5:
- Principal changes:
- Added support for the PCLm output format for driverless printing on
Mopria and Wi-Fi Direct printers.
This is the Google Summer of Code 2017 project of Sahil Arora.
The PCLm support requires QPDF 7.0.0 or later as part of Sahil's
work is there.
- If a PDF file to be printed contains an interactive form, flatten it
to static PDF so that further manipulation, like scaling, number-up,
... do not let the filled for content getting lost.
This is implemented by using the pdftocairo utility of Poppler and
if this fails Ghostscript (9.22 or later recommended).
This will probably be replaced by a QPDF-based solution later.
- Additional fixes for more reliable interactive PDF form printing.
- Completely rewrote the handling of resolutions reported by printers
by the PPD generator for driverless printing.
- Fixes in the "prettyprint" feature of the texttopdf filter.
- Eliminated all compiler warnings and other build process
improvements, especially compatibility with Poppler 0.58.0
- Documentation updates and fixes.
- CUPS Filters v1.17.9 release on 5 October 2017 (Till)
- cups-browsed: Applying option defaults from the
DefaultOptions directive in cups-browsed.conf got lost.
Re-introduced it (Bug #1414).
- cups-browsed: Get printer-location field from remote printers.
Thanks to Marek Kasik for the patch (Bug #1413).
- CUPS Filters v1.17.8 release on 28 September 2017 (Till)
- foomatic-rip: Change execution of renderer thread to fail
whenever any of its individual sub-comands fails.
Thanks to LUUM (luum at chromium dot org) for the patch (Bug #1412).
- foomatic-rip: Parent process now ignores SIGPIPE calls from
upstream/downstream CUPS filters, per
https://www.cups.org/doc/api-filter.html, while correctly
noting child process failures and exiting accordingly.
Thanks to LUUM (luum at chromium dot org) for the patch (Bug #1412).
- Build system: Fixed typo which broke the "--enable-gs-ps2write"
./configure command line option (Bug#1410).
- CUPS Filters v1.17.7 release on 18 September 2017 (Till)
- braille: Add a mirror option for graphical output.
Thanks to Samuel Thibault for this patch.
- braille: Rename the internal cups name of the Resize option
to the standard well-known and well-documented fitplot option.
Thanks to Samuel Thibault for this patch.
- braille: Add support for margins in graphical mode,
defaulting them to 15 points (a bit more than 5mm).
Thanks to Samuel Thibault for this patch.
- braille: Updated French translation.
Thanks to Samuel Thibault for this patch.
- braille: Add a PPD which generates UBRL output, i.e. Braille
expressed in Unicode. This is not useful for actual embossers,
but very convenient to check output to be embossed without
wasting paper.
Thanks to Samuel Thibault for this patch.
- braille: Add virtual BRF backend for generating
ready-to-emboss BRF files with CUPS, similarly to the
cups-pdf backend.
Thanks to Samuel Thibault for this patch.
- braille: Some tools seem to emit true/false instead of
True/False, so let us cope with it.
Thanks to Samuel Thibault for this patch.
- braille: "make uninstall" did not remove all the links.
Thanks to Samuel Thibault for this patch.
- braille: Add support for embossing MusicXML files, through
the FreeDots transcriptor.
Thanks to Samuel Thibault for this patch.
- braille: Add proper support for hardware margins on braille
embossers.
Thanks to Samuel Thibault for this patch.
- braille: Fix the disabling of the text margins in Index
graphics mode.
Thanks to Samuel Thibault for this patch.
- braille: Support for direct, structured embossing of XML and
XML-based file formats (like odt, docx, ...).
Thanks to Samuel Thibault for this patch.
- CUPS Filters v1.17.6 release on 15 September 2017 (Till)
- braille: Embossers can only emboss integer numbers of 2x4 cells.
Thanks to Samuel Thibault for this patch.
- braille: In Index graphical mode we need to disable the text
margins, since they come in earlier on the way to there.
Thanks to Samuel Thibault for this patch.
- braille: Also, we should always add a 1.6mm margin for taking
into account the width of dots.
Thanks to Samuel Thibault for this patch.
- CUPS Filters v1.17.5 release on 13 September 2017 (Till)
- libcupsfilters: In the PPD generator for driverless printing
renamed the "print-quality" option back to
"cupsPrintQuality" as the support for this option got fixed
in CUPS (CUPS issue #5090).
- braille: Improvements on the braille support for bitmap images:
Moves the graphical dot distance option to the image conversion
group, adds an option to avoid image resize, and makes the
rotation option easier by proposing to just fit paper instead of
fitting portrait or landscape.
Thanks to Samuel Thibault for this patch.
- braille: Support for embossing vector images as braille.
Thanks to Samuel Thibault for this patch.
- braille: Fix liblouis1.defs installation.
Thanks to Samuel Thibault for this fix.
- CUPS Filters v1.17.4 release on 10 September 2017 (Till)
- pdftopdf: If the input PDF file contains an interactive
form, flatten it to static PDF so that further manipulation,
like scaling, number-up, ... do not let the filled form
content getting lost.
This is implemented by using the pdftocairo utility of Poppler
and if this fails Ghostscript (9.22 or later recommended).
This will probably replaced by a QPDF-based solution later.
Thanks to Tobias Hoffmann for the QPDF-based detection of PDF
forms (Bug #1315, Ubuntu bug #1564249).
- CUPS Filters v1.17.3 release on 7 September 2017 (Till)
- bannertopdf: Make it working also with Poppler 0.58.0 and
newer (Bug #1408).
- gstoraster, pdftops, foomatic-rip: Added "-dShowAcroForm" to
all Ghostscript command lines where the input data format can
be PDF. With this and the fix of Ghostscript bug #698461 most
filled PDF forms should be rendered correctly by Ghostscript now.
- libcupsfilters: Do not check maximum resolutions of
raster-based PDLs, as implementation was incorrect and
reliability of PDLs is more important than maximum resolution.
- CUPS Filters v1.17.2 release on 25 August 2017 (Till)
- rastertopdf: Fixed outstanding bug in PCLm with JPEG (DCT)
compression. Now PCLm support is completely working.
- CUPS Filters v1.17.1 release on 25 August 2017 (Till)
- libcupsfilters: Added direct PNG printing to the PPD
generator, the one of CUPS has it, too.
- libcupsfilters: In the PPD file generator renamed the option
"cupsPrintQuality" into the IPP name "print-quality" as CUPS
does not update the "print-quality=4" entry in the filter
command line based on the setting of "cupsPrintQuality"
(CUPS issue #5090).
- libcupsfilters: Completely redone the way how to determine
the resolutions to use for the default resolution and print
quality option in the PPDs generated for IPP printers.
Resolution lists from IPP attributes are now read into sorted,
duplicate-free lists with wrong resolutions removed or fixed.
Resolutions actually used are the common ones between the
supported PDLs.
PDLs with inferior maximum resolution or with broken resolution
list are skipped
(Debian bug #868360, Ubuntu bug #1712019, CUPS issue #5088,
CUPS issue #5091).
- rastertopdf: Prefer RLE compression instead of Flate as
there are HP printers where Flate is buggy.
- Build system: Fixed help mesage for "--enable-driverless"
configure option (Bug #1405).
- CUPS Filters v1.17.0 release on 22 August 2017 (Till)
- rastertopdf, rastertopclm, driverless, cups-browsed,
libcupsfilters: Added support for the PCLm output format for
driverless printing on Mopria and Wi-Fi Direct printers.
This is the Google Summer of Code 2017 project of Sahil Arora
(sahilarora dot 535 at gmail dot com). Thank you very much for
your great work!
The PCLm support requires QPDF 7.0.0 or later.
- CUPS Filters v1.16.4 release on 22 August 2017 (Till)
- Build system: Switched over to C11 standard with GNU
extensions (-std=gnu11).
- Build system: Removed -pedantic flag as it is only needed
for compatibility with commercial compilers like the ones of
Windows (and we use GNU extensions anyway).
- libfontembed, texttopdf: reverted removal of anonymous
union.
- CUPS Filters v1.16.3 release on 21 August 2017 (Till)
- libfontembed: Reverted unneeded soname change.
- CUPS Filters v1.16.2 release on 18 August 2017 (Till)
- README: Minimum CUPS requirement of cups-filters is CUPS 1.4.x.
It does not build with earlier CUPS versions (Bug #993).
- driverless, foomatic-rip: Create relative symbolic links.
- All C/C++ files: Silenced all compiler warnings, at least
the ones appearing when building on Ubuntu Linux 17.10 with
GCC 7.1.0.
- README: Updated the introduction section to reflect the
current functionality of cups-filters, and the build
requirements for the Poppler-based filters
(C++11: Bug #1404, Build configuration of Poppler: Bug #1257).
Thanks to Roland Hieber (r dot hieber at pengutronix dot de) to
find out about this.
- pdftoopvp, bannertopdf, pdftoraster: Build with C++11
standard as some features of this standard are needed by
these filters (or by Poppler).
Thanks to Roland Hieber (r dot hieber at pengutronix dot de) for
the patch (Bug #1404).
- CUPS Filters v1.16.1 release on 11 August 2017 (Till)
- cups-browsed: Make timeouts for HTTP access to the local
CUPS daemon and remote IPP printers configurable.
Thanks to Cedric Dufour (cedric dot dufour at idiap dot ch)
for the patch (Bug #1387, Debian bug #852436).
- texttopdf: Allow bold and underline formatting to be used
together when using "prettyprint".
Thanks to Michael Moran (vampm at comcast dot net) for the patch.
- texttopdf: Allow to alter margins, and chars/lines per inch
when using "prettyprint".
Thanks to Michael Moran (vampm at comcast dot net) for the patch.
- texttopdf: When "prettyprint" is used, do not drop out of
C/shell comment mode too early.
Thanks to Michael Moran (vampm at comcast dot net) for the patch.
- October GSoC status
- Now, after the end of the Google Summer of Code Till started to
work on getting all the print-dialog-related projects upstream.
- Nilanjana's libraries and CUPS backend and Abhijeet's Google Cloud
Print backend are now hosted at OpenPrinting as they are
GUI-toolkit-independent.
They form the new Common Print Dialog Backends (CPDB) project.
Till has given this name as we do not get a common print dialog
for now, but instead common backends for print dialogs.
- The projects are the repositories cpdb-libs, cpdb-backend-cups, and
cpdb-backend-gcp on the new OpenPrinting GitHub:
https://github.com/OpenPrinting
- The first official releases from Nilanjana's project will most
probably be available very soon.
- This way the dependencies for the GUI work have their official
home so that the GUI changes can get accepted upstream and in
the distributions without problems.
- The LibreOffice changes from Yash are accepted by the LibreOffice
developers already. In the Ubuntu/Canonical developer meeting
last week in New York City Till talked with the LibreOffice package
maintainer of Ubuntu and he will backport the changes to the
LibreOffice version to be included in Ubuntu 18.04.
- The Qt dialog done by Anshul and Rithvik will not make it into the
current version 5.9 of Qt which will be the one in Ubuntu 18.04 but
Till talked with Ubuntu's Qt maintainer Gerry Boland (also in New
York City) and he will create a separate add-on package with the
dialog.
- Ubuntu 18.04 will still have the same GTK print dialog as the current
version, 17.10, as the first GTK/GNOME with Felipe Borge's new print
dialog will still take some time. So Till suggested in an IRC meeting
with Aveek to implement an interim solution: The current GTK print
dialog has already its backend concept, but it is only for the dialog
itself. So one could do an additional "adaptor" backend for the
current GTK dialog which accepts the new CPDB backends. Aveek asked
Nilanjana whether she would implement it voluntarily and she accepted.
She will work on this in a December time frame.
- This way we will get the new concept completely into Ubuntu 18.04.
- Rithvik stepped up voluntarily to contribute to OpenPrinting and Till
asked whether he would add "localhost" support to Avahi (see the GSoC
2018 project ideas below) as Till already asked the Avahi maintainer
(Trent Lloyd) for this feature and he does not find time for it.
This feature is needed for a fully standard-conforming IPP-over-USB
support. Rithvik accepted to do this.
- September GSoC status
- Success!
- All our 7 OpenPrinting students (and also all the 11 Linux Foundation
students) have passed the finals and so passed the whole program.
- Most OpenPrinting students have actually completed their projects but
some have still some work to do:
- The Qt dialog need some final polishing and API adaptation.
- QPDF-based PDF form flattening needs the implementation of the
support for the second of the two types of forms.
- All the dialog projects need to get integrated into the respective
upstream projects.
- All this should get completed in time for Ubuntu 18.04 LTS Feature
Freeze end of February 2018.
- Sahil's work on PCLm support got completed in time for Ubuntu 17.10
Feature Freeze and so PCLm support is upstream in cups-filters (1.17.2
and newer) and is included in Ubuntu 17.10, letting Ubuntu have
complete driverless printing support now:
- PDLs: PDF, PWG Raster, Apple Raster, PCLm.
- Standards: IPP Everywhere, Apple AirPrint, WiiFi Direct, Mopria.
- Also flattening of interactive PDF forms is implemented in Ubuntu's
(17.10) cups-filters (1.17.4 and newer) now, but not via QPDF:
- For the time being the pdftopdf filter calls external utilities
(pdftocairo or Ghostscript) to re-generate the documents as static
PDF files.
- There are also additional bug fixes related to PDF forms in
cups-filters and Ghostscript so that the forms with filled-in
content should generally get printed from now on.
- QPDF-based flattening is currently still worked on and it will get
used as soon as it gets available:
- Pranjal says that he will continue his work now.
- Rithvik is open to volunteer also on other OpenPrinting projects:
- Till told him that completing all print dialog work is our highest
priority but also sent him the GSoC 2018 project list of
OpenPrinting.

- Late October - GSoC Mentor Summit at Google
- Till reported this already in past months, but now we have additional
project ideas:
- We will use Aveek's very successful recruitment concept of starting
with finding students already in January again as we have been more
effective in finding good students.
- GSoC OP project ideas updated list for 2018:
- This will make it easier to write printer setup tools in practically
any programming language:
- Turn the scp-dbus-service of system-config-printer into C, either
as D-Bus service (if needed, would work out-of-the-box with many
GUIs) or as a C library with API (simpler).
- Urgently needed for IPP-over-USB printers to work conforming to
standards, not yet done due to lack of time of upstream maintainer:
- Full localhost support in Avahi.
https://github.com/lathiat/avahi/issues/125
- Probably only small changes needed, but requires to study and
understand the internals of Avahi.
- Interesting tool to make remote debugging of driverless printing
issues much easier:
- Let ippserver utility emulate printer based on text file with
IPP attributes.
https://github.com/apple/cups/issues/5093
- This task would improve the maintainability of cups-filters:
- Make all filters in cups-filters which use Poppler only use the
standard API of Poppler and no instable, inofficial APIs, switch
over to QPDF if more adequate (like bannertopdf for example).
https://bugs.linuxfoundation.org/show_bug.cgi?id=1409
- Interesting idea for a new concept of printing user experience:
- Content-oriented printer auto-selection: Cluster arbitrary
collection of printers (all available printers) into one queue
with merged PPD (all options of all printers available, option
conflicts if selection cannot be obeyed on one single printer),
user selects options (and document type, like text, photo, ...
is also submitted) and printer (or printers) to print the job on
get auto-selected by cups-browsed. User does not need to know
which printers are avaialable and what they are capable of.
- Support for new PWG standards (lower priority until appropriate new
IPP printers hit the market):
- SANE module for IPP Scan Servce driverless scanning (mainly for
multi-function printers).
- Support for IPP System Services (replacement of printer's
proprietary web admin interface by GUI in printer setup tool).
Will need Mike Sweet to complete his prototype implementation
in ippserver.
