- CUPS Filters Summary (Till)
- Currently released is 1.21.0.
- In this release bannertopdf is based on QPDF and not using Poppler through undocumented
interfaces any more, thanks to Sahil Arora's Google Summer of Code work. In addition,
several bugs got fixed, especially the duplicate execution of pdftopdf (both on client
and server) when one prints on a local queue pointing to a remote CUPS printer.
- CUPS Filters v1.21.1 planned changes (Till)
- Build system: Require QPDF 8.1.0 or later as it is needed by bannertopdf (Issue #56).
- CUPS Filters v1.21.0 release on 20 August 2018 (Till)
- libcupsfilters, cups-browsed, driverless, foomatic-rip, parallel:
Silenced warnings from newest gcc.
- libcupsfilters: When generating a PPD for driverless printing on a remote IPP printer,
make pdftopdf not be run by the local queue if the remote queue is a CUPS queue to avoid
running pdftopdf twice (CUPS Issue #5361).
- libcupsfilters, cups-browsed, driverless, bannertopdf, foomatic-rip, pdftops, pdftoraster,
rastertops, rastertoescpx, sys5ippprinter, beh: Fixed Coverity Scan issues. Thanks to
Zdenek Dohnal (zdohnal at redhat dot com) for the tests and the patches.
- bannertopdf: Switched over from using Poppler to using QPDF for generating the PDF pages.
With Poppler, unstable APIs were used which were subject to change. Thanks to Sahil
Arora for this project in the Google Summer of Code 2018 (Pull request #25).
- cups-browsed: Manually defined clusters ("Cluster" directive in cups-browsed.conf) caused
cups-browsed to crash.

- GSoC 2018 Status
- The GSoC 2018 has ended and all our six students have passed the final evaluations.
In total 12 of 13 students have passed in the projects of the Linux Foundation.
- Here are the final reports of the OpenPrinting students:
(1) Make the bannertopdf filter use QPDF instead of unstable/inofficial APIs of Poppler
Student: Sahil Arora
Mentors: Jay Berkenbilt
https://github.com/OpenPrinting/cups-filters/wiki/Google-Summer-of-Code-2018-%7C-The-Linux-Foundation-%7CImproving-
bannertopdf-filter-to-use-QPDF-instead-of-Poppler-APIs
Sahil has completed his task and his part in QPDF (8.1.0) is already included upstream
by Jay. Till has merged Sahil's part on bannertopdf itself into cups-filters (1.21.0).
(2) Enhancements for ipptool
Students: Akash Sharma, Lakshay Bandlish
Mentors: *Smith, *Danny, Aveek, Ira
https://github.com/akashs-india/ippsample/wiki/Google-Summer-of-Code-2018-%7C-The-Linux-Foundation---
Enhancements-for-Ipptool
https://github.com/lbandlish/Google-Summer-of-Code-2018-The-Linux-Foundation
Akash and Lakshay have done their tasks successfully and their work will get merged
upstream in PWG's ippsamples.
(3) PWG Raster "ippdoclint" program
Student: Rithvik Patibandla
Mentors: Smith, Danny, *Aveek
https://github.com/rithvikp1998/ippsample
Rithvik has also done his task successfully and his work will get merged upstream.
(4) Common Print Dialog Backends project
Student: Ayush Bansal
Mentors: Till, *James
https://github.com/ayush268/GSoC_2018_Documentation/blob/master/README.md
Ayush did not entirely complete his tasks, but he will continue to get them done.
Till has already merged the part in cpdb-libs/cpdbbackend-cups/cpdb-backend-gcp and put
the new cpdb-backend-file upstream on the OpenPrinting GitHub. The work on the GTK print
dialog will most probably get used as a distribution patch in Ubuntu.
(5) Content-oriented printer auto-selection
Student: Deepak Patankar
Mentor: *Till
https://github.com/deepak0405/GSoC2018_documentation/blob/master/README.md
Deepak did not entirely complete his tasks, but he will continue to get them done.
Till will merge it upstream in cups-filters.
- The voluntarily done Open Printing projects (outside of GSoC) are:
(1) Enhance "ippserver" to support the full range of IPP data types
Student: Aakash Lahoti
Mentors: Mike, *Ira, Danny, Aveek
Aakash successfully completed his tasks and they will get merged upstream.
(2) Qt print dialog completion
Student: Gaurav Purohit
Mentor: *Dongxu
Unfortunately, Gaurav did not do his work and disappeared.
Fortunately, Rithvik Patibandla volunteered to do this work.
- So the we were very successful and will get all our tasks done!
- Aveek and Till will attend the Google Mentor Summit in Sunnyvale, CA in October
- 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.
