Agenda
- Progress report
- Ubuntu Desktop Indabas announcement from Heather Ellsworth
- What is the Ubuntu Desktop Team Indaba? Indaba is a South African term for "a
conference or consultation between people". This will be a live stream event,
featuring members of the Ubuntu Desktop Team and members of the community. To
get a feel for what to expect, you can review the last Indaba event on YouTube
from July 30, 2021.
- To keep up a consistent cadence of these Indabas, we've decided to have them
he last Friday of the month, every month. (The actual time of day may change a
bit as we work out scheduling kinks that may arise),
- Ubuntu Desktop Indabas - OpenPrinting presentation on 27 August 2021
- In this month's Ubuntu Desktop Indabas edition, on Friday 27 August 2021 5pm UTC,
it is all about printing and what's new in this area. Therefore the special
guests will be Till Kamppeter and Michael Sweet (author of CUPS, PAPPL, did
important parts of IPP and Driverless Printing) and they will present the newest
state-of-the-art and of course be open for questions from the Ubuntu users.
- The event will be streamed live on YouTube and Twitch, both with live chat
(links on the announcement page).
- Thanks a lot to the creator and main organizer of the Ubuntu Indabas, Heather
Ellsworth, and also to the others from the team, Monica Ayhens-Madon and Rhys
Davies.
- See you there!
- Progress report
- OpenPrinting Micro-Conference
- Approved on 19 July 2021
- Final abstract published on 22 July 2021
- We got accepted for our third Openprinting Micro-Conference on the Linux Plumbers
Conference 2021 taking place from Monday to Friday 20-24 September 2021 at the same
place as last year: On the wider Internet!
- With the COVID-19 situation improving, some conferences are slowly coming back to
be in-person, but with still many travel restrictions we will have an online
conference again. But it has also an advantage, as we can freely choose the
speakers without having to worry about travel expenses. Also it is easier for
anyone to listen in on the live stream.
- The date of OpenPrinting's Micro-Conference is not yet determined, so please keep
an eye on the web site of Linux Plumbers (Aveek suggested Monday 20 September).

- PostScript Printer Application in the Snap Store, Call for testing on the
snapcraft.io forum and on the Ubuntu Discourse, more than 1300 installations via
Snap Store
- Till did not add anything new to the PostScript Printer Application as Till
continued his work on the printer driver retro-fit library. The PostScript
Printer Application will soon get switched over to be based on that library and
this way receive new features, especially easier handling of color mode, print
quality, and content optimization by the user.
- With appropriate features added to PAPPL we will be able to also add the
following:
- Support for string/text-style vendor options. Needs support in PAPPL (Patch
already applied in the Snap).
- Human-readable strings for vendor options. Needs support in PAPPL.
- Ink level check via ps_status() function. Needs support in PAPPL.
- Once having these features implemented, the PostScript Printer Application
will be complete so far.
- Progress report
- Currently Till is continuing with the work towards retro-fitting classic CUPS
printer drivers into Printer Applications. Till has continued to post sneak
previews of the most important milestones at the usual place.
- Here Till has especially done the following:
- Easy printing on every printer using standard IPP options
- Now the 3 IPP attributes print-color-mode, print-quality, and
print-content-optimize (or equivalent options under "Printing defaults" in
the web interface) will actually work, for nearly every existing PPD file
(please tell if they do not work with yours). This allows easy control of
every printer with the same operation scheme, no searching for the right
options for 99% of the printing tasks, including high quality photo printing,
quick and toner-saving draft prints, ..., and printing from restricted client
interfaces, like phones (iOS directly, Android with Mopria app). The correct
PPD options for the jobs are automatically selected internally. So simply
make use of your (old) printer's capabilities with only 3 options/attributes!
- For special needs not covered one only needs to switch the printer-specific
options away from "automatic-selection" to manually fine-tune. Do not forget
to get back to "automatic-selection" when done with the special job.
- Tested with following PPD files: HPLIP ("hpcups" driver), Gutenprint, Foomatic
("bjc250gs" and "hl7x0" drivers), PostScript PPDs from Ricoh, Toshiba, and HP.
- The most tricky part of this is to automatically find the options and choices
in the PPD file which needs to get set for switching between color and
grayscale printing, draft, normal, and high print quality, and for optimizing
the output for photo, graphics, text, and text-and-graphics jobs, and that for
~10000 PPDs, where everyone has his own ideas about which parameters to make
user-settable and how to name the options and choices for them.
- This is implemented in libppd in cups-filters (probably the only new PPD file
support feature which did not exist in CUPS). In the file ppd/ppd-cache.c, a
data structure for advanced properties of the PPD file is created (by the
ppdCacheCreateWithPPD() function. One of the items in the structure are the
so-called presets. To each of the 6 combination of settings for
print-color-mode (color/grayscale) and print-quality (draft/normal/high) a set
of PPD option settings (as key/value pairs) is assigned to allow quick and easy
printing with standard IPP attributes. Problem is that to make use of this
functionality one has to define the presets in the PPD (via APPrinterPreset PPD
attribute) but no one who creates PPDs did this actually and no one wants to
create a database of presets for ~10000 PPDs manually.
- So to finally (with PPDs already deprecated for many years and now active work
happening to get rid of them) put live into this great idea, Till has added an
algorithm to automatically generate the presets, in the new function
ppdCacheAssignPresets() in the same file. This function gives scores to all
PPD options on how much they influence grayscale/color printing and print
quality by the names of the options and choices, and by embedded PostScript
code affecting resolution, color space, and color depth. This way the
relevance of each option for the presets is determined and which choice to set
in each of the 6 presets.
- And in addition to print-color-mode and print-quality combos Till also
evaluates options for their influence on print-content-optimize
(auto/photo/graphics/text/text-and-graphics) in the same function to create
a preset for this. For auto the retro-fit library switches to photo on image
file input and for PDF input it determines from which app the PDF is coming
and chooses of the 4 content types appropriately.
- The resolution support implicitly also selects up to 3 preferred resolutions
(3 print qualities) and so the problem of PAPPL only supporting 4 resolutions
for a printer is overcome. In the Printer Application we simply select the
resolutions which are set by the presets. We also make use of the fact that
PAPPL does not set the default resolution but selects the lowest/middle/highest
resolution from the list for draft/normal/high print quality (note here that
for PAPPL selecting the correct "normal" resolution we have to list one
resolution twice in some cases - this is not a bug).
- Filter function chains for format conversions
- This change in the retro-fit library allows to use a chain of any number of
filter functions, both in the conversions for spooling printing mode and also
in the formats for streaming printing mode. This way we especially add the
pdftopdf() filter function (former pdftopdf CUPS filter), when PDF is the input
format in spooling mode, so that the pages get rotated into the destination
page format of the printer, the print-scaling attribute correctly applied, ...
and, in the streaming mode for printers with pure PDF PPD files, the PJL
commands of the PPD get correctly applied to the PDF output by the pdftopdf()
filter function.
- Streaming mode for filter functions
- In streaming printing mode (input is PWG/Apple Raster or an image) we instruct
the filters to stream the job data and not load the whole job into a temporary
file or into memory only to check which format it is and whether it perhaps
does not contain any page for printing. For that we supply the boolean option
filter-streaming-mode to the filters/filter functions in the filter chain. In
cups-filters, now pdftopdf(), ghostscript(), and foomatic-rip support this
streaming mode. pdftopdf() drops the whole processing by QPDF (adjustment of
page size and orientation, number-up, page-ranges, ...) and only applies
JCL/PJL commands from the PPD and the other two filters assume the input being
PostScript (the other alternative, PDF is not streamable anyway) and do not
check whether the input is a zero-page job.
- Support for CUPS backends
- Now we are adding the last major feature for the CUPS driver retro-fitting
framework: Support for CUPS backends
- Several classic CUPS drivers do not only consist of PPDs and filters but also
bring a CUPS backend, or several of them. HPLIP provides one to talk with USB
printers in IEEE-1284 packet mode, protocol 3, 7/1/3. By the way, protocol 1
is uni-directional stream, protocol 2 bi-directional stream (both supported by
PAPPL's own USB scheme and the usb CUPS backend) and protocol 4 is IPP-over-USB
(needs the ipp-usb extra daemon to work as a network IPP printer). Another one
coming with HPLIP supports faxing on many HP printers. Gutenprint has one for
the totally proprietary USB protocol of many dye-sub printers.
- To be able to correctly retro-fit this into a Printer Application, Till has now
added a custom PAPPL scheme, named "cups" to which a backend directory and
include/exclude lists for backends in that directory can get assigned. This
scheme integrates the backends in the Printer Application, listing all devices
which the backends discover (when all run in turn without arguments, like
lpinfo -v in CUPS) and allowing to add printers using them.
- This is not complete yet. It is an interim snapshot. For now, it only lists
the devices (so you see them in the "Device:" list of the "Add Printer" web
interface page, but when adding a printer using such a device, it will not
print, as the communication for job execution is not implemented yet. You only
can see that the devices got correctly discovered from within the Printer
Application. If you actually want to print you have to select one of PAPPL's
own devices.
- Till has also implemented the back channel and side channel concepts of CUPS'
filters and backends, so that classic drivers which use them, will correctly
work, and also some functionality of PAPPL's device concept will work better
then. Some of the implementation is in cups-filters (especially in the
filterExternalCUPS() filter function which Till has also added CUPS backend
support to).
- The implementation for actual job processing will come soon.
- 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, more than 2200 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.
- Unfortunately, no news on this.
- 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 18 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.
- Changes mainly happened in the build system and in the support for different system
platforms. Also new logos were added.
- There is no new entry in CHANGES.md.
- CUPS Filters Summary (Till)
- Current release is v1.28.9 on 15 June 2021
- Feature additions are principally done for retro-fitting classic CUPS drivers,
see details in the separate section, but also work of our GSoC students:
- Added auto-generation of presets for PPD files, to easily control the printing
via print-color-mode, print-quality, and print-content-optimize, with any of more
than 10000 PPD files.
- Added support for CUPS backends in both discovery (no arguments lpinfo -v) and
job processing mode, especially in the filterExternalCUPS() filter function.
- Added support for the back channel and side channel which CUPS uses for
communication between filters and the backend.
- ghostscript(): Added raster-only PDF and PCLm output support (for this also
reported a Ghostscript bug that the new "pclm" and "pdfimageXX" output devices
need seekable output files and the Ghostscript developers fixed it within a few
days!)
- foomatic-rip, ghostscript(), pdftopdf(): Added streaming mode for filters, to be
activated by the filter-streaming-mode boolean option.
- pwgtoraster(): Added support for borderless printing with overspray, stretching
the input image by some pixels to file the overspray size.
- libppd: In ppdCacheGetPageSize() also checked page size variants (like A4 and
A4.Borderless) taking the paper dimensions of the base size and only the margins
of the variants, to overcome different paper dimensions in the variants (for
example for borderless with oversparay).
- Improved the sample PPD files for PDF printers: Added borderless page size
definitions, removed redundant *cupsFilter2 lines, fixed bugs (all discovered on
testing under the retro-fitting Printer Application).
- Nearly all filters are filter functions now and can be used both with PPD files
and with printer and job IPP attributes.
- Also some bug fixes were done:
- pwgtoraster(): Do not apply back side orientation for duplex printing, it is the
responsibility of other filter functions.
- Several minor clean-ups and fixes
- Ubuntu Impish Indri (21.10, Feature Freeze next week) will come with cups-filters
v1.28.10 (to be released soon). The CUPS Snap currently uses v1.28.9. The
PostScript Printer Application Snap uses the current GIT master of cups-filters.
- CUPS Filters release v2.0.0 planned changes (Till)
- libcupsfilters, texttopdf: Moved core functionality of texttopdf into the
texttopdf() filter function (Pull request #404).
- libcupsfilters: The filterExternalCUPS() function. Now supports also to run CUPS
backends in discovery mode (without command line arguments and without input
stream, list of discovered printers in output stream).
- libcupsfilters: Added support for the back and side channels which CUPS uses for
additional communication between the filters and the backend into the filter
function infrastructure. Now filter functions can use these channels and also CUPS
filters or backends called via the filterExternalCUPS() function. Printer
Applications can easily create the needed pipes via the new function
filterOpenBackAndSidePipes() and clode them via filterCloseBackAndSidePipes() and
filter functions used as classic CUPS filters get the appropriate file descriptors
supplied by ihe filterCUPSWrapper() function.
- libcupsfilters: Added raster-only PDF and PCLm output support to the ghostscript()
filter function. Note that these are experimental and not yet suitable for using
in print filter chains, as they require a seekable output file and PCLm does not
support back side orientation for duplex.
- libcupsfilters, foomatic-rip: Added new streaming mode triggered by the boolean
"filter-streaming-mode" option. In this mode a filter (function) is supposed to
avoid everything which prevents the job data from streaming, as loading the whole
job (or good part of it) into a temporary file or into memory, interpreting PDF,
pre-checking input file type or zero-page jobs, ... This is mainly to be used
by Printer Applications when they do raster printing in streaming mode, to run
with lowest resources possible.
Currently foomatic-rip, ghostscript(), and pdftopdf() got a streaming mode. For
the former two PostScript (not PDF) is assumed as input and no zero-page-job check
is done, in the latter all QPDF processing (page management, page size adjustment,
...) is skipped and only JCL according to the PPD added.
- 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 and the PPD-retro-fitting Printer
Applications do not accept the PPDs with it.
- libppd: In ppdCacheCreateWithPPD() also support presets for print-ontent-optimize,
not only for print-color-mode and print-quality
- libppd: Auto-pre-fill the presets with most suitable options from the PPD files
with new ppdCacheAssignPresets() function (Only if not filled via "APPrinterPreset"
in the PPD). This way we can use the IPP options print-color-mode, print-quality,
and print-content-optimize in a PPD/CUPS-driver-retro-fitting Printer Application
with most PPDs.
- libppd: In the ppdCacheGetPageSize() function do not only check the fit of the
margins with the page size matching the job's page size (like "A4") but also the
margins of the variants (like "A4.Borderless"), even if the variant's size
dimensions differ from the base size (and the physical paper size), for example
for overspray in borderless printing mode (HPLIP does this). Also select a
borderless variant only if the job requests borderless (all margins zero).
- CUPS Filters release v1.28.10 planned changes (Till)
- 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
- Our 5 students have continued their work and made further progress. All the filters
of cups-filters (if not treated appropriately earlier) go through 3 student projects:
First getting turned into a filter function by Pratyush, after that made working
without PPD file but based on IPP attributes instead by Suraj, and finally landing
in the universal CUPS filter/filter function by Pranshu. This will get completed in
the last few weeks to go. Perfect team work!
- Also Bhavna and Divyasheel made good progress.
- On this month's OpenPrinting conference call all students participated again giving
a short screen-share-based presentation of their GSoC projects.
- There will be also a presentation of the GSoC projects on the PWG August 2021
Face-to-Face Meeting which takes place online on August 17-19, 2021. The GSoC
presentation will be on 18 August 2021 at 10:00am to 10:30am EDT (UTC−04:00), with
video demos of the students.
- Here is a short summary about what got done:
- cups-filters: Make sure all filter functions work without PPD files
Student: Suraj Kulriya
Mentors: Jai Luthra, Till Kamppeter, Dheeraj Yadav
- Suraj made the following filter functions working also without PPD file, based on
printer and job IPP attributes:
pdftopdf()
pclmtoraster()
- Suraj again created some library functions for common functionality, this time
ippRasterMatchIPPSize() and getBackSideAndHeaderDuplex() uploaded together with
the changes on pclmtoraster().
- cups-filters: Convert filters to filter functions
Student: Pratyush Ranjan
Mentors: Till Kamppeter, Dheeraj Yadav
- Pratyush converted the following CUPS filter to a filter function:
texttopdf()
- bannertopdf() is currently in the works.
- cups-filters: Create a single, universal CUPS filter to replace the chain of
individual filters
Student: Pranshu Kharkwal
Mentors: Till Kamppeter, Dheeraj Yadav
- Pranshu is not only creating a nice universal CUPS filter, but by this he is
also testing all the filter functions and so we discovered some oversights
where new filter functions were still using stdin or stdout at some places
instead of the new input and output file descriptors, making the universal
filter hang or somehow else misbehave (like outputting a zero-page job).
- Pranshu is up to texttopdf() with the support now. Most important still
missing part is testing it with CUPS and creating the needed MIME conversion
rule file.
- See Pranshu's work on his GitHub branch.
- GUI for listing and managing available IPP Print/Scan services (or
DNS-SD-advertised network services in general)
Student: Divyasheel
Mentors: Till Kamppeter
- Divyasheel is currently taking care of the correct device types getting listed,
services from the same physical device grouped and duplicates skipped. He also
takes care of the correct user action buttons be displayed for each service.
- See Divyasheel's work on his GitHub branch.
- PAPPL: Printer setup tool support and Scanning support
Student: Bhavna Kosta
Mentors: Jai Luthra, Till Kamppeter, Michael Sweet
- Principally mentored by Michael Sweet, Bhavna is making good progress with the
addition of scanning support to PAPPL. She has submitted a total of 4 pull
requests.
- The new pull request this month is "Add scanner-webif.c", adding web interface
pages for scanners.
