PDF is now the standard print job format rather than PS. Therefore traditional PostScript printers now also need a filter driver for printing.

See http://en.opensuse.org/Concepts_printing (http://en.opensuse.org/Concepts_printing) for details.

The network printer discovery protocol has changed. The native method to discover network printers is now based on DNS Service discovery (DNS-SD, ie via Avahi). The cups-browsed service from the cups-filters package can be used to bridge old and new protocols. Both cupsd and cups-browsed need to run to make "legacy" clients discover printers (that includes LibreOffice and KDE).

The IPP protocol default version changed from 1.1 to 2.0. Older IPP servers like CUPS 1.3.x (for example in SUSE Linux Enteprise 11) reject IPP 2.0 requests with "Bad Request" (see http://www.cups.org/str.php?L4231 (http://www.cups.org/str.php?L4231)).

To be able to print to old servers the IPP protocol version must be specified explictly by appending '/version=1.1' to either

Some printing filters and back-ends were moved from the cups package to the cups-filters package

Some configuration directives were split from cupsd.conf into cups-files.conf (see http://www.cups.org/str.php?L4223 (http://www.cups.org/str.php?L4223), CVE-2012-5519, and https://bugzilla.opensuse.org/show_bug.cgi?id=789566 (https://bugzilla.opensuse.org/show_bug.cgi?id=789566)).

CUPS banners and the CUPS test page were moved from the cups package the cups-filters package (see http://www.cups.org/str.php?L4120 (http://www.cups.org/str.php?L4120) and https://bugzilla.opensuse.org/show_bug.cgi?id=735404 (https://bugzilla.opensuse.org/show_bug.cgi?id=735404)).
