The libusb-based backend has once more functionality, especially bi-di works with all printers, without any manufacturer-wise restrictions, and second, it works also in systems with usblp module present, as it detaches the module from the printer before communicating and reattaches the module after finishing the communication. This means that it always "just works". The usblp-based backend is now only a fallback solution for systems without libusb. -------------------------------------------------------------------------- Reply at: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1061069/comments/3 ------------------------------------------------------------------------ On 2012-02-16T09:53:46+00:00 Jsmeix-x wrote: Probably of interest related to Samba and printing in Windows environment: http://www.cups.org/str.php?L2900 --------------------------------------------------------------------------- Given that the Windows drivers are now unsupported, we will no longer be investing time in new features or documentation for cupsaddsmb. --------------------------------------------------------------------------- Reply at: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1061069/comments/4 ------------------------------------------------------------------------ On 2012-02-16T10:10:16+00:00 Jsmeix-x wrote: FYI, some links to reports, discussions and replies from Michael Sweet: (German only): http://www.heise.de/newsticker/meldung/CUPS-1-6-unterstuetzt-Linux-schlechter-1435234.html (German only): http://www.heise.de/open/artikel/Kernel-Log-Apple-verschlankt-Cups-1435037.html http://www.heise.de/open/news/foren/S-Und-hier-ist-eine-Antwort-des- Entwicklers/forum-222028/msg-21443591/read/ http://cyberelk.net/tim/2012/02/06/cups-1-6-changes-ahead/ http://lists.fedoraproject.org/pipermail/devel/2012-January/161306.html http://lists.linuxfoundation.org/pipermail/printing- architecture/2012/002412.html http://lists.linuxfoundation.org/pipermail/printing- architecture/2012/002426.html http://lists.linuxfoundation.org/pipermail/printing- architecture/2012/002425.html Reply at: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1061069/comments/5 ------------------------------------------------------------------------ On 2012-02-16T10:38:47+00:00 Jsmeix-x wrote: Probably only of interest for exceptional use-cases http://www.cups.org/str.php?L3999 --------------------------------------------------------------------------- ... the PHP module has been removed from CUPS 1.6 and later. --------------------------------------------------------------------------- Reply at: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1061069/comments/6 ------------------------------------------------------------------------ On 2012-03-01T11:23:16+00:00 Jsmeix-x wrote: Regarding "Drop support for CUPS Browsing and Polling" (see comment #0) Ludwig Nussel suggested an interesting idea how to provide backward compatibility in this case: When a CUPS <= 1.5.x server should be replaced by a CUPS >= 1.6.x server in a bigger network printing environment with arbitrary client systems, the existing client systems expect to get CUPS Browsing information as it had worked all the time up to CUPS <= 1.5.x. Of course the admin could "just upgrade" all those arbitrary client systems with CUPS >= 1.6.x - but perhaps he might not like it ;-) To provide CUPS Browsing information to the clients a separated CUPS-Browsing-daemon could be implemented that gets print queue information from a CUPS >= 1.6.x server and creates CUPS Browsing information. The crucial point is that such a CUPS-Browsing-daemon is separated software and not a SUSE-specific add-on-hack for CUPS 1.6.x so that our CUPS 1.6.x is still in full compliance with upstream and admins who don't need or want such a CUPS-Browsing-daemon don't need to install its RPM package.
