Agenda
- Aveek scheduled weekly meetings on Wednesdays for renovation project
- Highlights of OP website renovation effort
- 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
- Several former GSoC students are picking up on tasks assigned by Aveek
- Various new OP web pages are in progress
- Two additional OP website pages have been added to the outline
- Driverless Printing and News/Events
- Most recent weekly meeting on Wednesday (14 November 2018)
- Till, Danny, Nilanjana
- Nilanjana's updates
- Dependency update (already pushed)
- Work on site layout to get similar to the one of LibreOffice
(still needs to be pushed)
- Till's updates
- Need to move of Foomatic's BZR repos and BZR repo of the printer/driver database
web app (http://www.openprinting.org/printers/) to GitHub to have all OpenPrinting
projects hosted in GitHub
- Need someone with PHP experience to update the scripts to sync the database with the
foomatic-db repo so that the GIT repo gets used
- Till explained how the database and the web app currently work and needed changes
- Till explained how driverless printing and Printer Applications would make the
database not needed any more at some point in the future
- Till explained that we actually replace the static part of the web site and on the
web app we only do the adaptation to foomatic-db being on GIT and cosmetic changes
(like using our new OP logo)
- Also talked about the logo and Till's idea that the new OP logo should contain a printer
(like the PWG logo contains a printer, too)
- Nilanjana and Danny agreed to that OP logo idea
- Ira subsequently expressed concerns about this OP logo idea
- More discussion is needed
- Need new OP logo - Aveek started a survey on new OP logo candidates on 12 November 2018 - Further discussion of Till's idea for an OP logo with a printer - Aveek will coordinate things to get this done
- PWG SC and OP have agreed on Lexington, KY location - Lexmark will host (Jeremy Leber has confirmed) - Joint PWG/OP Summit (Lexmark Host) - 30 April to 2 May 2019 - http://www.pwg.org/chair/meeting-info/meetings.html
- 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 - Sean Kau from (Chrome OS) contacted Till for a printing question recently - Sean Kau confirmed that David Valleau *is* still working on printing in Chrome OS, especially IPP-over-USB, so we can expect more contributions to ippusbxd.
- Avahi
- Till has had no answer from Trent Lloyd yet.
- Till considers Avahi to be unmaintained.
- Anyone wants to maintain it?
- Or knows someone?
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/

- 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 are looking into who/where in Linux Foundation.
- Aveek researched Outreachy further.
- OP would need to sponsor (for $5,500) at least one student
- Outreachy is not actually sponsoring any students themselves
