- Progress report - No update
- Progress report
- PostScript Printer Application in the Snap Store, Call for testing on the
snapcraft.io forum and on the Ubuntu Discourse, more than 1200 installations via
Snap Store
- Till continued on the support for CUPS filters used in PostScript PPD files,
also in preparation for retro-fitting of actual CUPS drivers, adding the
following features:
- Added foomatic-rip to the Snap (for PIN-secured printing on Ricoh)
- Support for CUPS' PPD extension for custom (string, integer, ...) option settings
- Added parameters like job UUID, date/time of submission/processing, ... to calls
of external CUPS filters
- On the Snap's included PAPPL applied the patch for custom string option support
(PAPPL's PR #142)
- With all this, now all ~4000 PostScript printer PPD files which come with the
Snap are fully functional, especially also supporting PIN-secured printing on
HP and all Ricoh brands.
- Note that these changes only apply to a few PostScript Printers and only to
enable features which are not used very often, but they are especially done
with general retro-fitting of CUPS printer drivers in mind, where CUPS filters
defined in the PPD file and string/text/numeric/fax number options are more
commonplace.
- 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. Here Till has especially done the
following:
- Turning the PostScript Printer Application into the retro-fit library
- To start the planned libpappl-retrofit library Till has taken the PostScript
Printer Application and modified the functions it is composed of to make them
"library-ready" and to generalize them to support all types of drivers and PPD
files, especially also non-PostScript ones.
- Till has done the following modifications on the original ps-printer-app.c
file:
- Get rid of global variables: Instead of using global variables for data
which should be accessible from all the functions Till has created a data
structure (pr_printer_app_global_data_t) for all these items and carry it
through the whole Printer Application via the context data pointer of the
callback functions.
- Generalization of data conversion methods: Depending on what kind of driver
(High-level graphics like PostScript or PDF or raster/bitmap graphics) you
want to accept different sets of input formats and therefore have different
format conversion methods. For spooling (usually high-level graphics)
conversions there is an array of pr_spooling_conversion_t records and for
streaming (usually raster) conversions an array of pr_stream_format_t records
now, with input and output data types, and filter functions to be used for
the conversion (Hint: If you need more than one filter function for a
conversion, simply use the filterChain() filter function).
- Easy configuration of the Printer Application by the implementer: One only
needs to put some basic data into a structure of type pr_printer_app_config_t
(which is a part of the global data structure), create the arrays of data
format conversion methods in priority order, make sure that the CUPS filters
and PPD files are at the right place, and call the Printer Application's main
loop. Can all be done in the main() function.
- Future library functions start with pr_..., the ones starting with ps_...
are specific to the PostScript Printer Application.
- As a sneak preview, Till has uploaded the code as an attachment to a GitHub
discussion. Or simply download it directly: ps-printer-app.c.txt
- To try it out, take the GIT master of the PostScript Printer Application and
replace its ps-printer-app.c file by this file. Then build the Snap (or build
classically with newest snapshots of cups-filters and PAPPL) as described in
README.md. As a result you should get the PostScript Printer Application with
its usual features, probably indistinguishable from the original, but with the
new innards. And this will also be the future of it, once the library is
started as a new GitHub repo at OpenPrinting.
- pwgtoraster() filter function
- Many of the classic CUPS drivers are the so-called CUPS Raster drivers, where
the job in a device-independent, designed-for-printing, standard raster format,
CUPS Raster, is fed into a CUPS filter, usually with name starting with
rasterto, which turns the input into the printer's native, often proprietary
language.
- One can easily recognize these filters by a line like:
*cupsFilter: "application/vnd.cups-raster 50 rasterto..."
in the PPD file.
- Retro-fitting those into a PAPPL-based Printer Application is not trivial,
especially if one wants to use the streaming raster-printing mode of PAPPL,
which is first required to be supported in a Printer Application and second
very useful for large jobs and especially large paper sizes and that even
more in combination with low-spec IoT devices.
- In spooling mode the retro-fit of these drivers is easy, as one can easily
call the filter chain which CUPS would use.
- In streaming raster mode we run into the problem that CUPS Raster supports
a lot of different, often exotic color spaces and that also in several
different color depths. This would mean, that the 5 raster printing callbacks
(start job, start page, print pixel line, end page, end job) need to be able
to convert the input into all these color spaces. To implement this only for
retro-fitting old drivers is a lot of work, especially as we have this already
nicely working in cups-filters, in the gstoraster and pdftoraster filters
(ghostscript() and pdftoraster() filter functions).
- So Till has gone another way: The pdftoraster() filter function has everything
to convert the 8-bit RGB raster output of Poppler into any of the color spaces
needed for CUPS Raster, and this filter already exists for a long time and just
works. So Till has derived a new pwgtoraster() filter function (there is also
a pwgtoraster CUPS filter executable for easy testing) from the pdftoraster()
filter function, throwing out Poppler and taking PWG Raster as input, allowing
only the color spaces 1-bit monochrome, 8-bit grayscale, and 8-bit RGB and
converting to the destination color spaces from these.
- As what the raster printing callbacks of a Printer Application receive is more
or less PWG Raster, Till can simply pass through this raster data when
pre-filtering with pwgtoraster() before calling the rasterto... filter defined
in the PPD.
- The new filter function has the following special properties:
- As streaming as possible: For chunked and banded color orders the data
streams "by-pixel-line", meaning that a line is read from the input,
converted, and immediately sent to the output, before the next line is read.
Only when the colors are ordered in planes the streaming is only "by-page".
- Pre-conversion of resolution and color space: The resolution and color
space/depth/order for the CUPS Raster data to be fed into the filter is not
simply defined by options and choices with intuitive names, but by the
PostScript code attached to the choices of the options in the PPD which are
selected for the job, like <</HWResolution[300 300]>>setpagedevice or
<</cupsColorOrder 1/cupsColorSpace 8/cupsCompression 2>>setpagedevice. The
CUPS filters collect all of the selected ones and interpret them with a mini
PostScript interpreter (ppdRaterInterpretPPD() in libppd) to generate the
CUPS Raster header (data structure describing the raster format) for the page.
Unfortunately, resolutions are not always defined in the "Resolution" option
(for example in "Print Quality" instead) or the resolution values do not
correspond with the human-readable choice names, same for color spaces not
always defined in "ColorModel". As with this the information the Printer
Application has from the PPD often does not reflect the driver's actual
requirements, the filter function pre-converts resolutions and color spaces
as needed.
- Note that the integration of this filter function into the retro-fit Printer
Application code is not yet done, meaning that a CUPS Raster driver retro-fit
will not work yet.
- Capturing of stderr output in the log
- Printer Applications with PAPPL have a nice logging facility and filter
functions in cups-filters support this logging facility. Now Till has added
capturing of stderr of the called external CUPS filter executable for logging
to the new filterExternalCUPS() filter function (see last month's news) and
also capturing of stderr of Ghostscript to the ghostscript() filter function.
This way the stderr output gets correctly into the log file of the Printer
Application instead of leaking into the syslog.
- 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 2000 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.
- A pull request with a suggested implementation of the new "cups" interface,
to which client Snaps which just want to print are supposed to plug
automatically got posted and discussion on it has happened. There got also
posted a test package of snapd with which Till could confirm that the
implementation is actually working (see Till's comments on the pull request).
- Once this pull request is merged, as a next step a pull request on snapcraft
for easily using the interface in client application Snaps is planned.
- In addition, the CUPS Snap uses newer upstream sources for its components now,
of QPDF version 10.3.2 and of cups-filters the current GitHub master branch
(2.x under development).
- 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.
- Michael Sweet presented his plans on CUPS 2.4.x and 3.x on the OpenPrinting
Summit/PWG Meeting.
- 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 Hirsute Hippo (21.04) comes with CUPS 2.3.3op2, the CUPS Snap and the
PostScript Printer Application Snap use the current GIT master.
- CUPS v2.4rc1 planned changes (Mike)
- The scheduler now supports the "everywhere" model directly (Issue #201)
- Further hardened `ippReadIO` to prevent invalid IPP messages from being
propagated (Issue #196)
- Add USB quirk for Canon MP480 (Issue #192)
- 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 pwgtoraster() filter function
- In filterExternalCUPS() and ghostscript() filter functions now stderr output
of external executables is captured for logging
- rastertopdf(), ghostscript(), texttotext(), imagetoraster(), pdftops(), and
imagetopdf() support printer and job IPP attributes now and so do not need
PPD files any more
- The pdftoraster CUPS filter is converted to a filter function now
- The rastertopwg filter of CUPS is now added as filter function rastertopwg()
- Also several bug fixes were done:
- cups-browsed: Make NotifLeaseDuration configurable and renew after half the
lease duration not 60 sec before end
- The pdftopdf() filter function now works correctly with unseekable input
- Removed unneeded test code from libfontembed
- Fixed pdftopdf() filter function to correctly support page ranges without upper
limit, like "10-"
- Minor fixes
- CUPS Filters release v2.0.0 planned changes (Till)
- libcupsfilters: Fixed pdftopdf() filter function to correctly support page ranges
without upper limit, like "10-" (Pull request #399).
- libcupsfilters, pwgtoraster: Created new pwgtoraster() filter function primarily
to print raster input (PWG Raster, Apple Raster, images) to CUPS Raster drivers
in driver-retro-fitting Printer Applications.
- libcupsfilters: Added new oneBitToGrayLine() API function which converts a line
of 1-bit monochrome pixels into 8-bit grayscale format (cupsfilters/bitmap.[ch]).
- libcupsfilters: Fixed possible crash bug in oneBitLine() function.
- libcupsfilters, rastertopwg: Converted CUPS' rastertopwg filter into the
rastertopwg() filter function.
- libfontembed: Removed unneeded fontembed/main.c and ttfread executable (Issue
#386).
- texttotext: Made the filter also work when instead of PPDs and CUPS options
printer and job IPP attributes are used (Pull request #385).
- libcupsfilters: Made ghostscript() filter function also work when instead of
PPDs and CUPS options printer and job IPP attributes are used (Pull request #383).
- libcupsfilters, pdftoraster: Moved core functionality of pdftoraster into the
pdftoraster() filter function (Pull request #381, #382).
- 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).
- 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).
- CUPS Filters release v1.28.9 on 15 June 2021 (Till)
- Bug fix release, fixes backported from the master (2.x) branch
- Ubuntu Hirsute Hippo (21.04) comes with cups-filters 1.28.8, also the CUPS Snap
currently uses this version. The PostScript Printer Application Snap uses the
current GIT master of cups-filters.
- libcupsfilters: Silenced compiler warnings
- libcupsfilters: Removed duplicate code in the apply_filters() function.
- driverless: If there are no driverless IPP printers available let "driverless"
terminate with exit code 0 and not 1, to follow CUPS' standard of backends in
discovery mode terminating with 0 if there are no appropriate printers found
(Issue #375).
- gstoraster, foomatic-rip: Fixed Ghostscript command line for counting pages as
it took too long on PDFs from evince when printing DjVu files (Issue #354, Pull
request #371, Ubuntu bug #1920730).
- cups-browsed: Renamed ldap_connect() due to conflict in new openldap (Issue #367,
Pull request #370).
- pdftoraster: Free color data after processing of each page (Pull request #363).
- cups-browsed: Always save "...-default" option entries from printers.conf,
regardless of presence or absence of PPD file (Pull request #359).
- cups-browsed: Start after network-online.target (Pull request #360).
- texttopdf: Set default margins when no PPD file is used (Pull request #356).
- GSoC 2021
- The mid-term evaluations are done now and all our 5 students have passed. Thanks
a lot to all our students for the great work they did during the first half of
the coding period.
- At this month’s OpenPrinting conference call, all students participated, giving
a short screen-share-based presentation of their GSoC projects.
- Here is a short summary about what has been accomplished so far:
- 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:
rastertopdf()
ghostscript()
texttotext()
imagetoraster()
pdftops()
imagetopdf()
- Suraj also created some library functions for common functionality needed here,
like a function which converts IPP attributes to option lists.
- cups-filters: Convert filters to filter functions
Student: Pratyush Ranjan
Mentors: Till Kamppeter, Dheeraj Yadav
- Pratyush converted the following CUPS filters to filter functions:
pdftoraster()
rastertopwg() (filter from CUPS)
- 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 making very good progress on the universal CUPS filter. Most
conversions already work. It also depends on the progress of Pratyush to
convert filters to filter functions.
- GUI for listing and managing available IPP Print/Scan services (or DNS-SD-
advertised network services in general)
Student: Divyasheel
Mentors: Till Kamppeter
- The graphical frontend part is mostly done and in the second half the
internal functionality, like Avahi browsing and so on, will be worked on.
- PAPPL: Printer setup tool support and Scanning support
Student: Bhavna Kosta
Mentors: Jai Luthra, Till Kamppeter, Michael Sweet
- The original project, "Firmware and other file handling in PAPPL" turned out
to be not that useful, so we decided to switch to other PAPPL work. Till
presented the list of feature requests on PAPPL and Bhavna decided to start
on features to support printer setup tools and after that to add scanning
support to PAPPL.
- For printer setup tool support, Till earlier requested to have device IDs
listed with the drivers when listing all included drivers of a Printer
Application with the drivers sub-command and to make Printer Applications
tell whether a printer is supported by them if one supplies the printer's
device ID.
- Bhavna implemented both these features via pull requests, the one for the
former got already merged and for the latter not yet.
- After that, Bhavna started on scanning support, which should not be too
difficult due to the fact that Michael Sweet already posted an excellent
project description.
- Here Bhavna already posted 3 pull requests: "Add scanner object and header
files", "Add scanner.c and scanner-accessors.c files", and "Add scanner-driver.c"
