 I have worked on this full-time since mid-2000, first at MandrakeSoft in Paris, from mid-2006 on I got paid by the Free Standards Group and from 2007 on by the Linux Foundation, for leading the OpenPrinting project, and in addition part-time by [Canonical](https://canonical.com/) for maintaining the printing part of Ubuntu. And from Feb 2012 on I got full-time employee of Canonical, to continue leading the OpenPrinting project.

 Also there has been a lot of development of the systems and environments for which we provide the print functionality. Our work will continue to improve software integration. For example, there will be continued work on the printer setup tools and print dialogs of different desktop environments and applications, packaging methods like Snap, Flatpak, Docker, ..., new forms of OS distributions (immutable core, all-Snap, ...), ...
