This completes the PDF printing workflow. - Color Management - colord to manage ICC profiles, gnome-control-center ("Colors" part) to upload/install profiles, ghostscript 9.04 to apply ICC profiles when rendering print jobs - foomatic-db - Package has patches, as there is currently no upstream repository - system-config-printer - Provides algorithmic parts (joining results of CUPS auto-detection which are for the same printer, printer/driver assignment, best driver) as a D-Bus service, to allow other printer setup tools using them. - Printer auto-detection also finds remote CUPS queues which are shared but not broadcast - XML-based rules for deciding which is the best driver for a printer - Google Cloud Print support (unofficial) - Chromium Browser: Enter URL "about:Flags" and enable the "Cloud Print Proxy" entry, Click wrench, "Preferences" -> "Under The Hood" and there will be a "Google Cloud Print" section near the end of the list. Shares all CUPS queues to Google Cloud Print. - Package "cloudprint": Install the package, run "cloudprint -d", log into your Google account. Also shares out your CUPS queues to Google Cloud Print. - Apple AirPrint support - All CUPS queues which are shared can be used with Apple iOS 4.2 (or newer) devices (iPhone, iPad, iPod Touch) via AirPrint (this also works already with Natty with all updates). - Ubuntu Developer Summit (UDS) in the first week of November (Till) - Preparing the next release - Ubuntu Precise (April 2012) LTS (Long Term Support) - Lars Uebernickel is at now Canonical, so he will attend the UDS - Sessions and meetings related to printing: - Co-Hosting (or even main hosting) of the OpenPrinting web site by Canonical, who are very experienced with web/cloud solutions: 100s of employees and volunteer developers collaborate through their infrastructure, Ubuntu One cloud storage for Ubuntu and Android, and Ubuntu Music Store. - Common Printing Dialog: Completing the UI design, integration in the desktops and in Ubuntu Precise. Meeting with Ubuntu Desktop and Ubuntu Desktop Experience teams. - User-visible, easy-to-use Google Cloud Print integration, most probably with the "cloudprint" package and GUI tool from the Ubuntu Desktop Experience team. - Use of GNOME3's printer setup tool using the D-Bus services of system-config-printer - Printing out of Ubuntu One into the cloud (Google, HP ePrint)
