Agenda
- Didier Raboud ("OdyX") is going on a 6-month sabbatical and therefore leaving his position
as printing guru of Debian. Thorsten Alteholz is overtaking here. OdyX and Till have
introduced Thorsten and he has already started off well.
- Thanks a lot to OdyX for all his work on Debian's printing part and the great collaboration
with Till and to Thorsten for overtaking where OdyX has left off.
- Progress report
- Linux Plumbers 2021 is approaching! It will start on Monday next week (20 September 2021)
right away with our OpenPrinting micro-conference on the first day!
- Yes, our micro-conference will take place on
- Monday, September 20, 2021, 7am - 11 am Pacific or 14:00 - 18:00 UTC
- The conference is all-online again, as 2020, due to the travel restrictions caused by
COVID-19.
- We will have the following sessions:
- CUPS 2.4/2.5
Presenter: Michael Sweet
- CUPS 3.0
Presenter: Michael Sweet
- Print Management GUI
Presenter: Till Kamppeter
- Common Print Dialog Backends
Presenter: Till Kamppeter
- Printer/Scanner Driver Design and Development
Presenter: Till Kamppeter
- Scanning in PAPPL
Presenter: Bhavna Kosta
- Note that these sessions are not just slide presentations. There are some slides to
introduce into the subject matter, but as the Linux Plumbers micro-conferences are
intended for, we will discuss about issues, decisions, design, ... to put our future
work into the right direction, and for answering questions from the attendees.
- The exact schedule is posted on the Linux Plumbers web site. Registered attendees can
participate interactively in the live discussions. Probably there will also be the
possibility for non-interactive watching of the micro-conference on YouTube and a
recording on YouTube after the micro-conference, as happened last year.
- Once a week, every Thursday in the US morning and the European afternoon, on the "Ubuntu
OnAir" YouTube channel of the Ubuntu community, the live event "Ubuntu Office Hours" is
taking place. In each episode a free software community memeber is invited to tell about
his project and what is happening in its community.
- In the October 7 episode (3 weeks from today) it is all about OpenPrinting. Organizer and
host Monica Ayhens-Madon has invited Till to talk about GSoC and the students Till has
mentored. There will not only Monica and Till be on the (virtual) stage but also
OpenPrinting program manager Aveek Basu and some of this year's (and perhaps also former
year's) GSoC students.
- We will talk about our GSoC work and its achievements, not only of code but also the
community growth, and what students have done after the summer, like mentoring the next
students or creating our current web site.
- We will also call for volunteers to join OpenPrinting and to contribute, and also answer
the spectators' questions which they post on the YouTube Live Chat of the session.
- Please mark in your calendars:
- Thursday, October 7, 2021, 17:00 - 18:00 UTC
- It will take place on YouTube and everyone can participate, without registration and free
of charge. Everyone can post questions on the YouTube Live Chat.
- For everyone who wants to get some technical background, Michael Sweet and Till also
talked about the ongoing changes in the architecture of printing with free software three
weeks ago in the Ubuntu Indaba (recording on YouTube).
- See you there!

- Progress report
- Printer Applications retro-fitting classic CUPS printer drivers consisting of PPD files,
CUPS filters, and CUPS backends, like currently the PostScript, Ghostscript, and HPLIP
Printer Applications, have a lot in common and share most of their code. Therefore Till has
continued the development of the code of the PostScript Printer Application by generalizing
it for any type of classic CUPS printer driver (see previous News posts and the sneak
previews of Till's work during the last months) and put it up on the OpenPrinting GitHub as
the PAPPL Retro-Fit Library.
- This library will also be the start of several other CUPS driver retro-fits making all the
drivers from the last (even more than) 21 years available for the new all-IPP, PPD-less
printing architecture. 21 years ago, Till migrated all printer drivers into CUPS, now he is
migrating them into the next architecture.
- The library makes creating a Snap of a CUPS driver as easy as creating a Snap of any other
application. It contains 98% of the C code needed to create a PAPPL-based Printer
Application around the CUPS driver. Only C code still needed is a main() function stub
setting the configuration of the Printer Applications (which features are used, which are
the resource/log/spool/state directories?) and perhaps a printer auto-discovery function
(Which printers are supported?). Otherwise one needs only the driver with all its files and
some extra packages like Ghostscript, libcups, libcupsfilters, libppd, ...
- The driver's files (PPDs, filters, backends) only need to get placed in the appropriate
directories for the Printer Application to find them. No need to change the code of the
drivers, so it is also easy to retro-fit unmaintained drivers, drivers for which one does
not have an appropriate printer to test, and even proprietary, closed-source, binary-only
drivers.
- Then one can create print queues with the printers being auto-discovered (by PAPPL's
backend and/or included CUPS backends) and the model/driver (PPD file) can be
automatically or manually selected (each "Driver Name" drop-down entry on the "Add
Printer" web interface page is one PPD file).
- When printing a job the IPP attributes are automatically mapped to the best-fitting PPD
option settings, to easily allow to make use of the features of the printer, even on
clients with limited print dialogs, like phones or IoT devices. The web interface also
allows to manually set defaults for all PPD options for more detailed control. Even options
requiring CUPS PPD extensions, numeric, string, password, fax number, ... options are
supported.
- All current retro-fitting Printer Applications (PostScript, Ghostscript, and HPLIP) are
using this library now.
- The Printer Applications created with this library can also be run directly on the system,
without being in a Snap, especially the Test Printer Application which comes with the
library and sets its resource directories to use all the PPD files, filters, and backends
of the system’s classic CUPS installation. This allows testing installed drivers how they
work under a Printer Application or allows installed drivers to be used with an installed
CUPS Snap.
- All important features are included now. Further development of the library will go with
the development of PAPPL and the needs of the Printer Applications. Especially the
following features will get implemented/supported as soon as they are implemented/fixed in
PAPPL:
- Support for string/text-style vendor options. Needs support in PAPPL (Patch already
applied in the Printer Application Snaps).
- Human-readable strings for vendor options. Needs support in PAPPL.
- Ink level check via ps_status() function. Needs support in PAPPL.
- Progress Report
- Ghostscript Printer Application in the Snap Store, 194 installations via Snap Store
- If you want to use an (older) printer which is not a modern driverless IPP printer and is
also not a PostScript printer (which would be supported by the PostScript Printer
Application then) Then this is the right Printer Application for you.
- It supports ~5000 different printer models, mainly with drivers from the well-known
Ghostscript but also some others. The printer model support is based on OpenPrinting's
printer support database (Foomatic). Especially many standard laser (PCL 6/XL, PCL 5c/e,
PCL4) and dot matrix (ESC/P, OKI, IBM, ...) but also many printers with proprietary print
data formats are supported. There are not only model-specific entries to choose from, but
also generic entries for the common formats for the case your printer is not explicitly
listed.
- The Printer Application gives access to all the options of the former PPD files inside its
web interface ("Device Settings", "Media", "Printing Defaults") but can be easily used from
any IPP-compliant client application or device. The standard IPP attributes are
automatically converted to the best-fitting PPD option settings, especially for color,
quality, and content optimization.
- These drivers already ship for many years with most common Linux distributions (Ubuntu,
Debian, Fedora, SUSE, ...) and have made many user's printers work and these printers will
continue to work in environments where only Printer Applications (and no classic printer
driver packages) are supported.
- In the future more drivers will get added to the Snap of this Printer Application,
especially smaller, unmaintained driver projects for which it does not make much sense to
clutter the Snap Store with another Printer Application.
- Progress Report
- HPLIP Printer Application in the Snap Store, 616 installations via Snap Store
- Right after having published the Ghostscript Printer Application I have continued with the
HPLIP Printer Application, to cover the printers supported by the printer driver of HPLIP.
- Creating this one was much more complex than the Ghostscript Printer Application as HPLIP
is a suite of printer drivers, PostScript PPD files (with extra CUPS filters), scanner
drivers and command-line and GUI utilities. It also has many quirks like excessive use of
hard-coded absolute file paths in the source code, utilities written in Python, an
x86-32/64-only binary-only code blob in the driver ... while Ghostscript and Foomatic are
much more packaging-friendly.
- As scanning support in PAPPL is not ready yet, scanning on multi-function printers is not
yet supported. Also loading the proprietary driver plugin will be added later.
- Printing is now possible on all non-PostScript and PostScript printers from HP and Apollo
which HPLIP supports without its proprietary plugin. More than 3000 different models from
~30 years.
- For maximum compatibility both PAPPL's standard backends and the "hp" backend of HPLIP are
available, the former for bi-directional access (poll accessory configuration settings of
PostScript Printers), the latter for simultaneous printing and scanning on the same device
and perhaps also special needs of some printer models.
- Note that HP is one of the best manufacturers in terms of supporting driverless IPP
printing and scanning, so most newer HP printers work best without this Printer
Application, even if HPLIP (and so this Printer Application) supports them.
- Note also that HPLIP has many bugs which are fixed in the Debian/Ubuntu and RedHat/Fedora
packages by a high amount of distribution patches whereas this Printer Application uses the
"raw" upstream source code. I will soon switch to the packaging GIT repository of Debian,
as soon as the new Debian printing maintainer has updated it to version 3.21.8.
- Progress Report
- PostScript Printer Application in the Snap Store, Call for testing on the snapcraft.io
forum and on the Ubuntu Discourse, 1484 installations via Snap Store
- The PostScript Printer Application is now switched over to use the new PAPPL Retro-Fit
Library.
- This means that now we have fully automatic mapping of job IPP attributes to the
best-fitting PPD option settings to make printing as easy as possible with standardised
user-settable options and from any client device including phones.
- Also most of the development and debugging happens centrally in the retro-fit library.
- Note that HP’s PostScript PPD files are in both this and the HPLIP Printer Application
now. This should make the life easier for users. Some do not know whether their printer is
PostScript, but it is from HP, so the HPLIP Printer Application will always work, others
have a bunch of PostScript printers of different manufacturers, including HP, they will be
able to support them all with a single Printer Application.
- Progress report - No update.
- Progress report
- CUPS Snap in the Snap Store, Call for testing on the snapcraft.io forum and on the Ubuntu
Discourse, 2564 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 Till has good news now: Till has talked with them about when he can expect the merging
into snapd and they say that they will do it 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.
- 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 below)
- 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.
- Development of CUPS 2.4 is in progress, currently mainly fixing of bugs which were
reported to Apple's CUPS GitHub in the last 19 months.
- Ubuntu Impish Indri (21.10, Feature Freeze next week) will also come with CUPS
2.3.3op2. The CUPS Snap and the PostScript Printer Application Snap use the
current GitHub master.
- The CUPS in Impish Indri has a distribution patch porting the fully automatic
job-IPP-attribute-to-PPD-option-settings mapping from cups-filters, which we use in all
retro-fitting Printer Applications to CUPS, so that when sharing a print queue under the
new Ubuntu one has the same ease of printing to it from any device, especially phones. A
Pull Request for upstream inclusion of this feature is posted and under discussion.
- There will be news and discussion about CUPS 2.4.x and 3.x with Michael Sweet on the
OpenPrinting Micro-Conference on the Linux Plumbers 2021 on Monday (20 September 2021).
- CUPS v2.4rc1 planned changes (Mike)
- Fixed documentation and added examples for CUPS' limited CGI support (Apple #5940)
- Fixed the `lpc` command prompt (Apple #5946)
- Stubbed out deprecated `httpMD5` functions.
- Printer driver deprecation wasn't mentioned in CUPS Web UI
- 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.
- Improved the auto-mapping of job IPP attributes to PPD option settings (presets). Several
new rules added during further driver retro-fitting work, especially also for Foomatic's
"PrintoutMode" composite option.
- The GSoC students have completed conversion of the filters into filter functions and
making the filter functions also use job and printer IPP attributes as alternative to
PPDs and option settings.
- A Pull Request for a single, universal CUPS filter, calling sequences of filter
functions, reducing external function calls, is posted and shortly before merging.
- Support for the print-rendering-intent IPP attribute in filter functions.
- Use of log function for the log messages produced by the color-management-related
functions of libcupsfilters.
- In the ieee1284NormalizeMakeAndModel() function extract driver info with regular
expression (needed by libpappl-retrofit).
- In filterExternalCUPS() sanitize the device URI (for CUPS backends) and env variables to
assure that passwords do not get into log files.
- Also several minor bug fixes were done.
- CUPS Filters release v2.0.0 planned changes (Till)
- foomatic-rip: Debug message was wrongly sent to stdout and not to log (Issue #422).
- libcupsfilters: In ghostscript() pass on LD_LIBRARY_PATH to Ghostscript
- libcupsfilters: In color-management-related functions use the log function instead of
logging right to stderr.
- libcupsfilters: In ieee1284NormalizeMakeAndModel() extract driver info with regular
expression.
- libcupsfilters: Support print-rendering-intent IPP attribute in ghostscript(),
mupdftoraster(), and pdftoraster() filter functions.
- libcupsfilters, mupdftoraster: Moved core functionality of mupdftoraster into the
mupdftoraster() filter function (Pull request #412).
- textbrftoindex: Fix control character filtering (Pull request #409)
- libcupsfilters, bannertopdf: Moved core functionality of bannertopdf into the bannertopdf()
filter function (Pull request #407).
- libcupsfilters: Also allow supplying a regular expression to extract driver information
when the input string is a PPD's *NickName.
- CUPS Filters release v1.28.11 planned changes (Till)
- foomatic-rip: Debug message was wrongly sent to stdout and not to log (Issue #422).
- CUPS Filters release v1.28.10 on 17 August 2021 (Till)
- Bug fix release, fixes backported from the master (2.x) branch
- Ubuntu Impish Indri (21.10) will come with cups-filters 1.28.10. The CUPS Snap currently
uses v1.28.10. The PostScript Printer Application Snap uses the current GIT master of
cups-filters.
- Sample PPDs: Add borderless page size definitions to Generic PDF Printer, HP Color LaserJet
CM3530 MFP PDF, and Ricoh PDF Printer PPD files.
- Sample PPDs: From the PDF PPD files removed the unneeded "*cupsFilters2: ..." line. For
CUPS it does not make any difference.
- libcupsfilters: Fixed pdftopdf filter to correctly support page ranges without upper limit,
like "10-" (Pull request #399).
- libcupsfilters: Use wildcard tag (IPP_TAG_ZERO) search for "media-type" and
"media-type-supported" in the PPD generator (Pull request #398).
- implicitclass, parallel: Added missing newlines at error messages.
- libfontembed: Removed unneeded fontembed/main.c and ttfread executable. Eliminates the
dependency on DejaVuSans.ttf (Issue #386).
- gstoraster: Refactor the filter a little to clarify handling of page counts and set
job-impressions for TotalPageCount in PWG-Raster header (Pull request #394).
- cups-browsed: Make NotifLeaseDuration configurable and renew after half the lease duration
not 60 sec before end. The early renewal improves reliability on busy systems a lot. For
easier development and debugging short durations from 300 sec on can get selected (Pull
request #378).
- GSoC 2021
- The Google Summer of Code 2021 has ended successfully for OpenPrinting! All our 5 students
have passed final evaluations and did great work. The projects are mostly completed, only
some debugging and polishing is currently taking place. Most of the code is already
committed to the respective upstream GIT repositories (and partially already in use in the
CUPS-driver-retro-fitting Printer Application Snaps).
- There was a presentation of the GSoC projects on the PWG August 2021 Face-to-Face Meeting
which took place online on August 17-19, 2021. There we have shown a video where every
student has presented his/her project.
