on opensuse 12.1 plain fresh install and tumbleweed
kde4.7.x and 4.8.x
libreoffice 3.4.5 and 3.4.4
with printers samsung clp-320n(network cable) and clp-300(usb cable)
drivers from The Samsung Unified Linux Driver Repository
used alien on this Index of /suldr/pool/debian/extra
to convert in rpm

on opensuse 12.1 I installed the official Samsung unified Linux driver, I met problems to print with both the printers;
no printing pdf, printing double and so on;
so I tried to install on another pc linux mint;
I installed the drivers from http://www.bchemnet.com/suldr/smfpv3.html;
everything went well and I didn't faced any problem on printing;
libreoffice 3.4.4 can print landscape!!!!!

so I converted drivers from The Samsung Unified Linux Driver Repository to rpm with alien;
I installed on opensuse 12.1 by yast;
the printing was very better with this drivers than the samsung official ones;
but in suse 12.1 I cannot print landscape with libreoffice 3.4.4 and 3.4.5!!!!
in libreoffice it shows everything correctly in landscape, but when I print the sheet is in portrait;
if in libreoffice I print on file, it creates a correct pdf file in landscape and when I print from okular the printing is ok in landscape.

after all this tests my suspect is that the problem is something in suse 12.1, am I wrong?? is a bug or I can solve?
