Agenda
- Aveek scheduled weekly meetings on Wednesdays for renovation project
- Highlights of most recent OP website weekly meeting (3 October 2018)
- Due to security concerns (e.g., database attacks), it has been decided that
WordPress will not be used as the framework for the new OP website
- Instead Jekyll has been selected as the framework for the new OP website
- A dummy OP home page will be created by second week of October
- Two additional OP website pages have been added to the outline
- Driverless Printing and News/Events
- Need Driverless Printing pointer on OP home page
- Driverless Printing page to be developed
- PWG has requested addition of IPP Everywhere and IPP Everywhere logo
- Need new OP Logo - Aveek is looking into new OP Logo, now that GSoC 2018 has finished - We need to first settle on a concept - Perhaps a student can do design or else we'll pay a professional designer - No progress on the Logo - Aveek will coordinate things to get this done
- PWG SC proposes Lexington, KY w/ Lexmark host (Jeremy Leber agrees) - Unanimous approval of Lexington site from OP call participants - Joint PWG/OP Summit (Lexmark Host) - April, May, or June? (TBD) - http://www.pwg.org/chair/meeting-info/meetings.html
- We are moving to GitHub now: https://github.com/OpenPrinting - No updates
- Moved to new upstream home: https://github.com/OpenPrinting/ippusbxd - No updates
- Avahi
- Till has had no answer from Trent Lloyd yet.
- Till considers Avahi as unmaintained.
- Anyone wants to maintain it?
- Or knows someone?
- We really need this project to get upstream-maintained again. Especially important
for Debian to adopt the patch for localhost support. See
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909564
- Michael Biebl, maintainer of the Debian package of Avahi, says there
"We'll consider cherry-picking the patch once it has been reviewed and
applied upstream."
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/

rdar://37837581)
- Fax queues did not support pause (p) or wait-for-dialtone (w)
characters (rdar://39212256)

- CUPS Filters Summary (Till)
- Currently released is 1.21.3.
- Due to Ubuntu's feature freeze for 18.10 (to be released on October 18, less than 2 weeks
from now), Till is only adding bug fixes, so that the upstream code can be simply put
into Ubuntu, without need of patches in the Ubuntu package.
- Several bug fix releases were done, especially to fix regressions introduced by the
Coverity scan issue fixes from 1.21.0 but also some other small fixes.
- CUPS Filters v1.21.4 planned changes (Till)
- pdftoraster, pdftoopvp, pdftoijs: Poppler removed memCheck and gMemReport functions,
remove appropriate calls (Issue #62, Pull request #66).
- CUPS Filters v1.21.3 release on 3 October 2018 (Till)
- foomatic-rip: Reset stdin after replacing the underlying file descriptor (Issue #58).
- CUPS Filters v1.21.2 release on 2 September 2018 (Till)
- cups-browsed: Fixed freeing of literal string caused by Coverity Scan issue fix (Debian
bug #907399).
- CUPS Filters v1.21.1 release on 26 August 2018 (Till)
- Build system: Require QPDF 8.1.0 or later as it is needed by bannertopdf (Issue #56).
- GSoC 2018 Mentors Summit
- 12-14 October - GSoC Mentor Summit in Sunnyvale, CA
- Aveek and Till will attend this mentor summit in person
- GSoC 2018 Status
- Deepak Patankar is continuing his work on automatic printer selection by the Job
attributes in cups-browsed. Till is in contact with Deepak around once a week.
- Should Deepak not finish, he already did several valuable things for cups-browsed
which Till will include upstream. Till did not start with this yet as Ubuntu is in
Feature Freeze and therefore Till's only doing bug fixes on the upstream code.
- Ayush Bansal will also complete his work.
- Many of the GSoC students who worked with OpenPrinting in 2017 and 2018 are volunteering
to participate in the OpenPrinting web site renovation.
- GSoC 2019 Concepts
- Here are Till's first thoughts on what could be done in next year's GSoC.
- Central point will be the Printer Applications deprecating the classic Printer
(and Scanner) drivers of CUPS filters and PPDs (or SANE modules).
- Printer Applications can also be used to easily get distribution-independent driver
packages when packaging them as a snap. Due to the network-style communication
(ipp://localhost:<port>/...) with CUPS no special snap interfaces are needed.
- GSoC 2019 Projects
- Here we could do the following projects
(1) Generic Framework to turn legacy drivers consisting of CUPS filters and PPDs into
Printer Applications.
(2) Creating a Printer Application out of Foomatic.
(3) Creating Printer Applications from HPLIP, foo2zjs, Gutenprint, ...
(4) Creating Printer Applications for arbitrary SANE-supported Scanners to make them
available as driverless IPP network Scanners. This would allow for easily making
distribution-independent Scanner driver packages.
(5) Create a SANE driver for IPP Scanners, so that Linux applications can use IPP
network Scanners. As long as the hardware manufacturers do not provide appropriate
devices, this driver will server for using the Scanner drivers of (4) above.
(6) Linux GUI application (can be part of GNOME printer tool) to admin MF devices using
IPP System Service.
- With (4) and (5) we would get the very first user of the IPP Scan Service standard,
even before the hardware industry picks it up. It would also be a sample implementation
of both ends (Client and Server) of the IPP standard.
- Outreachy for future Open Printing projects.
- Similar to GSoC, but twice a year, higher stipends ($5,500 vs $2,500)
- Linux Foundation is already registered w/ Outreachy.
- Aveek and Till will look into who/where in Linux Foundation.
- Aveek will research Outreachy further.
