  • CUPS Snap: Waiting for @ijohnson’s pull request on snapd for the cups printing interface to get merged by the snapd team (especially a review by @jamesh is missing). @ijohnson tells that only fixing the bug of needing to re-connect “cups” interface after a snapd update and iimplementing the additionally requested validation is still needed.
  • cups-filters: Continued testing and bug-fixing to approach the 2.x release. Now the change of cups-browsed’s implicitclass backend from using external filter executables to using filter function is completed and all bug discovered during this switchover are fixed. Especially now one can finally have cups-browsed-generated print queues pointing to a raster-only printer and these work correctly. In addition asymmetric unprintable margins of printers are correctly handled by pdftopdf() now, Kyocera’s and UTAX’ PPDs can be correctly accessed in the PostScript Printer Application, and cups-browsed’s queue naming is now synced with the naming of cupsd’s temporary queues, to avoid duplicate entries in print dialogs. See details in the January news post. Also backported many fixes to 1.x and released cups-filters 1.28.11 upstream.
  • CUPS Snap: Updated the contained cups-filters to the 2.x GIT master, to include the recent fixes, especially cups-browsed using filter functions and working with raster-only printers.
  • foomatic-db: Got PPD files for UTAX printers and there are more to come. UTAX printers are re-branded Kyocera models.
  • Google Summer of Code 2022: The timeline is available now! Contributor candidates got CUPS and cups-filters GitHub issues as assignments and are working on them.
  • OpenPrinting: January News Post.
  • Bugs.
