- https://github.com/OpenPrinting/openprinting.github.io/issues
- Progress report
- ippusbxd got some bug fixes and improvements from Fletcher Woodruff (PR #38
and #43) and Thierry Hucahrd (PR #41). Thanks very much to the contributors.
- In ipp-usb, Alexander Pevzner added lots of bug fixes and hardware
workarounds/quirks. Thanks to all the users who have tested with their
devices and reported their problems. Probably many more users will have
their device just work due to that testing.
- ipp-usb is on the way into Red Hat (according to Alexander Pevzner) and also
into Debian. Above is the link to the packaging request and Didier "OdyX"
Raboud, printing maintainer of Debian, has taken it up and uploaded the
appropriate package. Also thanks to Brian Potkin for posting the request.
- Progress report - See IPP over USB below.
- Progress report
- Jai Luthra is our OP GSoC 2020 student.
- Device discovery via DNSSD, SNMP.
- Command line interface (papplMainloop)
- PCL driver (CUPS rastertohp) example
- Next for work is the packaging and documenting the driver.
- Progress report
- Alexander Pevzner, author of the IPP-over-USB daemon ipp-usb and of the
AirScan/eSCL/WSD scanner driver sane-airscan asked us to post this news of
his work
- sane-aiscan
- Though sane-airscan is not included into any any major distro, its
popularity among users grows, and it receives more testing on a growing
variety of hardware.
- Most of newly discovered issues are either firmware bugs that require
workarounds, or certain corner cases, like not running Avahi daemon or
device announces 2 IP addresses, one of them is not reachable from host.
- A couple of hard to reproduce crash bugs were found and fixed with the
help of clang static analyzer.
- Added packaging for ARM32 and ARM64, targeting Raspberry Pi users.
- There are already 7 devices in the list that support WSD, but don't
support eSCL, so the idea to implement WSD was useful.
- Integration into SANE project seems to be finally stuck. Meanwhile
Alexander works directly with Benjamin Gordon on integration into
ChromeOS and Zdenek Dohnal on integration into Fedora.
- ipp-usb
- Initially ipp-usb was targeting distro maintainers. That is why its
initial documentation is rather short technical and no binary packaging
was provided.
- Recently Alexander has discovered certain interest among end users to
install and use ipp-usb. So Alexander has provided packages for many
distros, including ARM32/ARM64.
- ipp-usb is also known to work on mipsel Linux, but Alexander can't
provide packaging for this platform due to OBS limitations.
- As with sane-airscan, growing popularity implies more testing, and some
issues were discovered and fixed.
- Some users were interested in directly exporting printer into local
network segment, which is safe and reliable with ipp-usb. In result,
incompatibilities with iOS devices were found and fixed (Android devices
were always working). This fix was ported to ippusbxd too.
- Most of other issues are of the same class: device returns truncated
HTTP response, and ipp-usb stuck forever, waiting for missed part of
response, which effectively blocks the USB connection.
- The solution is the same in all cases: properly set "Connection: close"
or "Connection: keep-alive" header in outgoing HTTP request.
Unfortunately, different devices require different settings of this
header.
- As it is hard to organize testing on hundreds of devices, a more generic
solution of this problem is required.
- Zdenek Dohnal seems to begin working on integration of the ipp-usb into
Fedora.
- The projects are not only on their way into Red Hat but also into Debian.
Packaging requests for both ipp-usb and sane-airscan have been posted
and Didier "OdyX" Raboud, printing maintainer of Debian, has taken up
both and uploaded the appropriate packages. Also thanks to Brian Potkin
for posting the request for ipp-usb.
- Progress report
- The Snap is now renamed to simply be the "cups-snap" project on the
OpenPrinting GitHub and "cups" in the Snap Store.
- The build service of the Snap Store is now attached to our GitHub repository
and builds the CUPS Snap for 6 architectures (amd64, i386, armhf, arm64,
ppc64el, and s390x). Note that the CUPS Snap cannot be downloaded and
installed through the Snap Store yet as it will need new "cups" and
"cups-control" interfaces (https://github.com/snapcore/snapd/pull/8920)
which are not yet added to snapd. Till has already tested them and they work
as expected.
- Till has tested the CUPS Snap a lot during the last month and fixed a lot of
bugs, especially making all components build on all the 6 architectures
supported by the Snap Store, making utilities like lpoptions, cupsfilter, and
driverless work correctly, making DNS-SD-service-name-based URIs correctly
resolve if the service is local (Printer Application or IPP-over-USB), and
updating the README.md to reflect the renaming and the current use of interfaces.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/
- CUPS Summary (Till)
- Current CUPS release is still v2.3.3 on 24 April 2020 (Apple)
- Security fixes
- No further releases or GIT commits. Also 79 open issues and 18 open Pull
requests. Only a few answers from upstream developers.
- Till has asked several people about what is happening here but did not get
really clear answers. But it seems that the learning needed by the new
Apple CUPS engineers, COVID-19, and the switch of Apple from Intel to ARM
architecture have much influence on this.
- Till is thinking about, as a last resort, temporarily forking CUPS so that
distribution maintainers can collaborate on fixing bugs there.
- CUPS Filters Summary (Till)
- Currently release is v1.27.5 on 9 April 2020.
- No new release, due to the fact that Till is currently working on a major
feature addition which he wants to complete before releasing v1.28.0 and
which is important for the switch over to Printer Applications:
- libppd
- One important point for the CUPS Snap is that it does not support
classic printer drivers, consisting of PPD files and filters. So for
using CUPS Snap as the default CUPS implementation in a Linux
distribution, all existing printer drivers need to be turned into
Printer Applications, and this with a minimum effort of coding.
- Most of these drivers (probably all except Gutenprint) are difficult
to get converted by their original authors, as they are not maintaining
the drivers any more, supported printers are old and no one wants to
code for them any more, drivers are simply only a big bunches of PPD
files, no source code, driver is proprietary, closed source, ...
- So we need a way to retro-fit these drivers by wrapping them into
Printer Applications with the lowest coding effort possible and also
without needing to modify the original driver executables.
- This works best if we use the driver's PPD files inside the Printer
Application and so we need to handle PPD files, although the PPD
handling support was removed from CUPS and especially libcups.
- To avoid inventing the wheel again, writing a lot of handling code
for a totally obsolete file format, Till has grabbed all the PPD
handling functions from libcups (current GitHub state, CUPS 2.3.3) and
put them into the new libppd which Till has added to cups-filters.
- libppd has the following properties
- All PPD-handling-related functions from libcups (except loading the
PPD from a CUPS queue or polling a PPD repository on a CUPS server)
are overtaken.
- Also the CUPS-private functions related to PPDs are overtaken and
added to libppd's public API.
- Other private or internal functions are overtaken from libcups as
they are needed for the PPD-related functions to work. They are not
added to the API.
- Some functions of tools and utilities like ippeveprinter and ippeveps
are overtaken.
- All API functions have names starting with "ppd" and written in
camel-case, some needed to get renamed for that.
- libppd is separate from libcupsfilters, so it does not need to get
included in a Printer Application which uses the functionality of
cups-filters but does not use PPD files.
- NOTE: This is NOT to encourage printer driver developers to continue
to create new PPD files for new printers. It is ONLY meant to be used
for retro-fitting existing classic CUPS drivers and PostScript PPD
files. There will be no further development on the library's code,
especially no new PPD format extensions.
- The next release of cups-filters, v1.28.0, will contain libppd for the
first time. It is already, shortly before completion for v1.28.0, in
the GitHub repository in the ppd/ subdirectory.
- Further work:
- pclmtoraster
- GSoC student Vikrant Malik's project is to extract raster data from
PDf files which only consist of embedded raster images, not containing
text, fonts, or vector graphics. This allows for higher print quality
of such PDFs as input files (for example scanned files) and also to
convert PDF output of scanners into dedicated raster formats like TIFF,
PWG Raster, ...
- One known raster-only PDF format is HP PCLm and therefore Vikrant has
started his work by adding the new pclmtoraster filter to cups-filters.
He also worked a lot on converting raster formats between color spaces
an bit depths.
- Bug fixes
- Many bug fixes in cups-browsed, the filters, and the sample PPDs have
been performed, often with the help of our GSoC students or candidates
doing assignments. Thanks to all of them.
- Note also that the sample PPD files have moved to the new ppdfiles/
subdirectory.
- CUPS release v1.28.0 planned changes (Till)
- Build system: Remove '-D_PPD_DEPRECATED=""' from the compiling command lines
of the source files which use libcups. The flag is not supported any more
for longer times already and all the PPD-related functions deprecated by CUPS
have been moved into libppd now.
- libcupsfilters, libppd: Older versions of libcups (< 2.3.1) had the enum name
for fold-accordion finishings mistyped. Added a workaround.
- cups-browsed: Remove left-over local queues from the previous session more
quickly when CUPS legacy browsing is turned on.
- cups-browsed: Left-over local queues from the previous session for which
the corresponding remote printer did not appear again did not get removed
as they were considered externally overwritten.
- gstoraster, gstopdf: Add option "-dDoNumCopies" to Ghostscript command line
if we are outputting PDF (called via gstopdf wrapper) and the number of
copies supplied to CUPS is 1 (4th command line argument). In this case we
convert incoming PostScript to PDF and need to respect embedded PostScript
commands to implement the number of copies (Issue #255, CUPS Issue #5796,
OpenSUSE bug #1173345).
- imagetoraster: Potential null dereference fix (when no valid PPD is supplied,
Pull request #256).
- libppd: Added the new libppd library overtaking all the PPD handling functions
from libcups as they are deprecated there and will probably get removed with
the next CUPS version. This form of conversion is mainly intended for
converting classic printer drivers which use PPDs into Printer Applications
without completely rewriting them. Side effect that all the compiler warnings
about deprecated libcups functions went away and so cups-filters is free of
warnings again. The library still needs some testing and optimization.
- Sample PPDs: Renamed source directory from "ppd/" to "ppdfiles/"
- cups-browsed: Call cupsGetNamedDest() only if "OnlyUnsupportedByCUPS No"
- Sample PPDs: Corrected ColorModel default for Generic PWG Raster PPD to
Color (Pull request #247).
- cups-browsed: Mark the temp queue as cups-browsed-generated during setting
printer-is-shared (Pull request #246).
- cups-browsed: Remove mentions of README and AUTHORS files in the man page
(Pull request #244).
- pclmtoraster: Added new filter to extract Raster data from raster-only PDF
files, here for the special case of PCLm files (Pull request #243, #257).
- Sample PPDs: In Generic-PDF_Printer-PDF.ppd add option to switch between
color and grayscale printing (Pull request #237).

- Some GSoC 2020 student work reports for the first month (June):
- Mohit Mohan
- Hi everyone, I am Mohit Mohan, junior at IIT Kanpur in the CSE department.
I am a GSoC student this year, working with Open Printing on the project
"Speed/Scaling optimisation of cups-browsed". As the first coding period
completed a few days back, I wanted to inform you all about what I did in
that time.
- But first a bit about the problem with cups-browsed. cups-browsed is a
very useful tool for networks with large numbers of printers but, as it
discovers the printers on the network one by one, as the number of printers
increases, the time taken to create a queue for all of the printers greatly
increases.
- To understand more about this issue, I tested cups-browsed with different
numbers of printers, to find out how much time it takes to create queues.
Next thing to find out was where it was taking most time. To do that, I
found out time taken by some of the important functions during a queue
creation. From the results, it was quite clear that update_cups_queues()
was taking the most time. This function actually creates the queue.
- As my mentors Till Kamppeter and Deepak Patankar suggested, I looked at
where it was taking most of the time in update_cups_queues(), and found
out that it was cupsGetNamedDest(), which is a part of the CUPS API to get
a specific destination from the list of available destinations. We tried
all available alternatives, but none of them worked faster, so in the end
we decided to stay with cupsGetNamedDest(). You can find the results at
the link above.
- I also created a design document for implementing multi-threading in
cups-browsed. You can find that design document at the link above.
- In the next phase, I am working on implementing multi-threading in
cups-browsed.
- Jai Luthra
- ...here’s my progress with PAPPL.
- Device discovery via DNS-SD, SNMP.
- Command line interface (papplMainloop)
- PCL driver (CUPS rastertohp) example
- Next work is for the packaging and documenting the driver.
