Attendees
Agenda
- Lots of new participants and discussion on the GitHub repository - Sahil is leading the project and managing the commits - The OP website renovation will probably complete in April or May 2019
*** Joint PWG/OP Summit (Lexmark Host) - 16-18 April 2019 *** - Ira plans to attend in person - by driving from Southeast MI to Lexington, KY - Till plans to attend in person - Danny plans to call in - Aveek (GSoC 2019) plans to call in - Michael Vrhel (Artifex, Ghostscript/muPDF) plans to attend in person - Sean Kau (Google, Chrome OS) plans to attend in person
- Ubuntu 19.04 "Disco Dingo" release milestones - DONE - Feature freeze 21 February 2019 - UI freeze 14 March 2019 - Kernel freeze 1 April 2019 - Ubuntu 19.04 release 18 April 2019
- We are continuing to move OP repositories to GitHub https://github.com/OpenPrinting - See OP website renovation notes above
- Moved to new upstream home https://github.com/OpenPrinting/ippusbxd - No updates
- Avahi
- Avahi is very important for driverless IPP Print, Scan, Fax, and System Service,
but also for the OS and other major applications in general.
- Trent Lloyd is one of the two original authors of Avahi (the other is Lennart
Poettering), which makes it more difficult to take this project away from Trent.
- Till was recently in a Canonical meeting for a week where the different engineering
teams of Canonical meet. At that meeting, Till met Trent in person and talked with
him about the Avahi issue and Trent said it is no problem for him to merge the patch.
Till met Trent on the first day of that meeting and Trent promised to still apply the
patch during the meeting week (but he did not).
- Now Till has sent two weekly reminder e-mails, but Trent did not even answer.
- So at the April OpenPrinting Summit we must see with the Google guys how they will do
the ippusbxd and Printer Applications (local discovery) on Chrome OS and perhaps
take over this development work to Linux.
- Kurt Pfeifle (kurt dot pfeifle at gmail dot com, the person who made Till find CUPS
back in 2000 (and becoming OP Manager), wrote on the OpenPrinting mailing list:

None other than Lennart Pottering. :)

----------
- But this is not correct.
- Avahi was initially created by Trend Lloyd in early 2004. Trent was certainly
inspired by Apple's Bonjour, which unfortunately was not initally Open Source, so
there was a strong motivation to implement a FOSS ZeroConf stack, since all of the
relevant specs (mDNS + DNS-SD) were already there in the IETF, and open.
- Later that same year Lennart Poettering started a similar project to implement
mDNS/DNS-SD functionality called "FlexMDNS".
- Both projects united and merged their code bases sometime in 2005. Although Till has
no idea which of the two authors wrote more lines of code that still exists in today's
code base, Poettering surely had a heavy impact on today's Avahi.
- Apple released Bonjour as Open Source software under the Apache License in 2006.
- Avahi's name certainly was Trent's decision, and he started his implementation half
a year before Poettering.
- Poettering's last commit into Avahi's GitHub code was in Sept 2012. Trent's last
commit was in late February 2019. The last time Trent merged a major pull request
was in August 2018.
See https://github.com/lathiat/avahi/commits?author=lathiat.
- According to https://github.com/lathiat Trent now works for Canonical.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/
- CUPS Summary (Till)
- Current stable release is CUPS 2.2.10.
- No new releases.
- CUPS 2.3b7 (14 December 2018) was a bug fix release that solved some minor issues of
CUPS 2.3b6. There is no CUPS 2.2.x counterpart to it.
- CUPS 2.2.10 (7 December 2018) was a bug fix release that solved a security issue and
several other bugs, mostly related to driverless IPP printing.
- CUPS Filters Summary (Till)
- Current release is CUPS Filters v1.22.1.
- Bug fix release, mainly to let the get-printer-attributes IPP requests for
auto-generating PPD files for driverless IPP printing use the same attributes as CUPS
uses. There are also some small enhancements for Braille support.
- Changes planned for CUPS Filters release v1.22.2 (Till)
- cups-browsed: Do not do IPP request for printer-is-shared option for remote cups
queues with CUPS 2.2.x and newer (Pull request #91).
- cups-browsed: Fix crash bug when reading "Cluster" directive from configuration file
(Issue #94).
- driverless: Updated man page as now also Mopria and Wi-Fi Direct printers are supported.
Mentioned also ippusbxd.
- Progress on GSoC 2017 and 2018 unfinished projects
- Till says progress continues on finishing former GSoc projects - see CUPS Filters.
- F2F meeting of OP GSoC students
- Aveek and decided to organise a F2F meeting with OP GSoC 2017/2018/2019 students.
- F2F meeting of OP GSoC students September 2019 in India, since most OP GSoC students
are from India.

- GSoC 2019 Summary
- The org application of the Linux Foundation is submitted and on 26 February 2019
we will know whether Linux Foundation got accepted by Google.
- Aveek has started to search for and interview GSoC 2019 OP students.
- Aveek says that we should be very strict w/ accepting other Linux Foundation
projects and mentors, based on last year's experience.
- According to Google, the project idea list is very important for a mentor
organization to be accepted in GSoC 2019.
- 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.
- Since the OP website renovation will not complete before the start of the
mentoring organization application window, because we are applying as the
Linux Foundation (and not as OpenPrinting) anyway, the main page of the idea
list and the group pages of all non-OpenPrinting groups will have to be at
their old locations anyway. So it is no problem to create our OpenPrinting
idea list at the old website location for now, too - migrating already.
- As soon as we complete our OP website renovation, we will maintain our
OpenPrinting project ideas on our new website, adding a link that project
idea management has moved to our new idea page on the old (Linux Foundation)
website and also change the link on the main page of the Linux Foundation's
GSoC participation.
- GSoC 2019 Project Ideas
(1) Generic Framework to turn legacy drivers consisting of CUPS filters and PPDs into
Printer Applications.
(2) Create a Printer Application out of Foomatic.
(3) Create Printer Applications from HPLIP, foo2zjs, Gutenprint, ...
(4) Create 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. Until the hardware manufacturers have provide appropriate devices,
this driver will serve for using the Scanner drivers of (4) above.
(6) IPP: Linux GUI application (can be part of GNOME printer tool) to administer MFD
devices using IPP System Service.
(7) cups-filters: pdftoraster filter needs to be done without need of unstable Poppler APIs.
(8) IPP: ipptool test suite for IPP System Service.
ipptool is a command line tool for issuing IPP requests and receiving printer's/server's
responses. ipptool is maintained as free software in the ippsample collection from the
IEEE-ISTO Printer Working Group (PWG). ipptool is used for development and debugging of
IPP-related software and for PWG self-certification for IPP Everywhere printers for
driverless printing.
Develop additional ipptool test scripts for all new operations, objects, attributes
defined in IPP System Service v1.0 (e.g., Create-Printer).
(9) IPP: ipptool test suite updates for IPP Everywhere v1.1.
ipptool is a command line tool for issuing IPP requests and receiving printer's/server's
responses. ipptool is maintained as free software in the ippsample collection from the
IEEE-ISTO Printer Working Group (PWG). ipptool is used for development and debugging of
IPP-related software and for PWG self-certification for IPP Everywhere printers for
driverless printing.
Develop additional ipptool test scripts for all new operations, objects, attributes
required for compliance with IPP Everywhere v1.1 (e.g., Identify-Printer).
Note: With (4) and (5) we would get the very first use 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.
