CUPS >= 1.6 has major incompatible changes compared to CUPS up to version 1.5.4 in particular when printing via network:

The IPP protocol default version increased from 1.1 to 2.0. Older IPP servers like CUPS 1.3.x (for example in SLE 11) reject IPP 2.0 requests with "Bad Request" (see ~~http~~://www.cups.org/str.php?L4231 ). By adding '/version=1.1' to ServerName in client.conf (e.g., ServerName older.server.example.com/version=1.1) or to the CUPS_SERVER environment variable value or by adding it to the server name value of the '-h' option (e.g., lpstat -h older.server.example.com/version=1.1 -p) the older IPP protocol version for older servers must be specified explicitly.

CUPS Browsing is dropped in CUPS but the new package cups-filters provides the cups-browsed that provides basic CUPS Browsing and Polling functionality. The native protocol in CUPS for automatic client discovery of printers is now DNS-SD. Start cups-browsed on the local host to receive traditional CUPS Browsing information from traditional remote CUPS servers. To broadcast traditional CUPS Browsing information into the network so that traditional remote CUPS clients can receive it, set "BrowseLocalProtocols CUPS" in <code>/etc/cups/cups-browsed.conf</code> and start cups-browsed.

Some printing filters and back-ends are dropped in CUPS but the new package cups-filters provides them. So cups-filters is usually needed (recommended by RPM) but cups-filters is not strictly required.

The cupsd configuration directives are split into two files: cupsd.conf (can also be modified via HTTP PUT e.g. via cupsctl) and cups-files.conf (can only be modified manually by root) to have better default protection against misuse of privileges by normal users who have been specifically allowed by root to do cupsd configuration changes (see ~~http~~://www.cups.org/str.php?L4223, CVE-2012-5519, and https://bugzilla.opensuse.org/show_bug.cgi?id=789566).

CUPS banners and the CUPS test page are no longer supported since CUPS >= 1.6. The banners and the test page from cups-filters must be used. The CUPS banner files in <code>/usr/share/cups/banners/</code> and the CUPS testpage <code>/usr/share/cups/data/testprint</code> (which is also a CUPS banner file type) are no longer provided in the cups RPM because they do no longer work since CUPS >= 1.6 (see ~~http~~://www.cups.org/str.php?L4120 ) because there is no longer a filter that can convert the CUPS banner files. Since CUPS >= 1.6 only the banner files and testpage in the cups-filters package work via the cups-filters PDF workflow and the cups-filters package also provides the matching bannertopdf filter.

Line 77:

With PDF as the standard print job format traditional PostScript printers can no longer print application's printing output directly so that a conversion step in the printing workflow is required that converts PDF into PostScript. But there are also PostScript+PDF printers that can print both PostScript and PDF directly.
