Agenda
- Investigated the upstream source code of Avahi to see whether one can make it advertising services on localhost local-only. It seems that one can do so with a small set of changes. This way we could do a standard- conforming advertising of IPP-over-USB printers via DNS-SD (and as a side effect Avahi will also work on machines without network at all).
- Continued working on support for driverless printing. - Several changes and fixes done on the system-config-printer in Ubuntu 17.04 (Zesty Zapus, release this Thursday, April 13) to support driverless printing. Printers get set up fully automatically, but manual setup is also improved. See "Driverless Printing" section in - https://wiki.ubuntu.com/ZestyZapus/ReleaseNotes
- Aveek Basu (Lexmark) reached out to Indian schools and selected 6 students to work on the Common Printing Dialog in this Google Summer of Code. - Pranjal Bhor from last year will work on cups-filters and QPDF so that filled PDF forms get printed correctly.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/
- CUPS summary (Till)
- Besides general bug fixes there are a lot of fixes and improvements on
driverless printing and the PPD generator for driverless printing.
- CUPS v2.2.3 release on 28 March 2017 (Mike)
- The IPP backend could get into an infinite loop for certain
errors, causing a hung queue (<rdar://problem/28008717>)
- The scheduler could pause responding to client requests in
order to save state changes to disk
(<rdar://problem/28690656>)
- Added support for PPD finishing keywords (Issue #4960, Issue
#4961, Issue #4962)
- The IPP backend did not send a media-col attribute for just
the source or type (Issue #4963)
- IPP Everywhere print queues did not always support all print
qualities supported by the printer (Issue #4953)
- IPP Everywhere print queues did not always support all media
types supported by the printer (Issue #4953)
- The IPP Everywhere PPD generator did not return useful error
messages (Issue #4954)
- The IPP Everywhere finishings support did not work correctly
with common UI or command-line options (Issue #4976)
- Fixed an error handling issue for the network backends (Issue
#4979)
- The default cupsd.conf file did not work on systems compiled
without Kerberos support (Issue #4947)
- The "reprint job" option was not available for some canceled
jobs (Issue #4915)
- Updated the job listing in the web interface (Issue #4978)
- Fixed some localization issues on macOS
(<rdar://problem/27245567>)
- CUPS Filters summary (Till)
- Currently released is 1.13.4, 1.13.5 is in the works and has already
many changes.
- Bug fixes and improvements for driverless printing support.
- Updated the PPD generator for driverless printing to the GIT state
of CUPS' PPD generator
- CUPS Filters v1.14.5 release work-in-progress (Till)
- foomatic-rip: When called via the utility cupsfilter from
CUPS, foomatic-rip was not able to read the PPD file with
the file name supplied as environment variable PPD (Bug
#1388).
- driverless: Improved error message output.
- libcupsfilters: Fixed error handling of the PPD file
generator for driverless printing, so that callers get
decent error messages.
- libcupsfilters: Do not generate a PPD file where the only
output data format is JPEG, as JPEG does not support
multi-page documents.
- libcupsfilters: Let PPD generator skip broken page size
records and add warnings for debugging to the PPD.
- libcupsfilters: Updated PPD generator to match with the
current GIT state of the one of CUPS.
- braille: Automatically select a table according to the
current locale.
- braille: Update for liblouis table list.
- braille: Added support for text margins.
- cups-browsed: When creating a local queue for a remote CUPS
printer, add the line '*APRemoteQueueID: ""' to the PPD file
so that CUPS sets the CUPS_PRINTER_REMOTE bit for the
printer type of the local queue (Bug #1386).
- Aveek Basu (Lexmark) reached out to Indian schools and found 6 students
to work on the Common Printing Dialog in this Google Summer of Code.
- Canonical stopped the efforts on the phone, Unity 8, MIR, and QT, so for
the QT side of the print dialog we will find Canonical-independent QT
mentors and we will use Canonical's QT print dialog code (which they
abandoned) as base for the QT side in our print dialog efforts.
- On the GTK side there is also a new print dialog in the works which is
supposed to get released in around 2 years from now. So we will
concentrate on common backends for both GTK and Qt dialogs and also make
the current GTK print dialog supporting these backends.
- We will create backends for the three print technologies CUPS queue, IPP
network printer, and Google Cloud Print this summer, to get all
applications supporting these print technologies and easy addition of
new print technologies in the future.
