= Features/CUPS1.6 = https://fedoraproject.org/wiki/Features/CUPS1.6 Feature owner(s): Tim Waugh <twaugh@xxxxxxxxxx>, Jiri Popelka <jpopelka@xxxxxxxxxx> Update CUPS to the latest upstream release and use PDF rather than PostScript as baseline document format. == Detailed description == CUPS 1.6 was released in July 2012 and has brought several important changes * Merged Fedora's patch for color management using colord * Merged Fedora's patch for mDNS/DNS-SD support using Avahi * Removed support for CUPS Browsing and Polling * The CUPS Browsing protocol is currently the primary mechanism for CUPS- to-CUPS printer queue discovery on Linux. It works by having each CUPS server periodically broadcast UDP packets on port 631 announcing its available queues, and listening for broadcasts from other CUPS servers. CUPS Browsing protocol has no longer been meeting the requirements of current networking technologies, and in fact has had some bad effects on wireless networks due to the use of UDP broadcasts. Rather than trying to address these issues by introducing a new and incompatible update to the protocol, the existing mDNS/DNS-SD standards can serve as a ready replacement and actually has been used in CUPS for many years now. * All filters and backends not used by Mac OS X have been dropped * These filters and backends, together with the filters for the PDF printing workflow are now hosted as the cups-filters project at linuxfoundation.org. PDF printing workflow * Currently CUPS uses PostScript as the common format for manipulating print jobs. We want to switch the standard print job transfer format from PostScript to PDF, which has many important advantages. * Additional filters for the PDF printing workflow have been added to the cups- filters project. _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
