The rpm can be downloaded from download.opensuse.org here
I couldn't find it on RPMfind.net, but it maybe that it isn't on all the mirrors yet. I haven't tried it yet, but I'll post a note when I have.
That didn't work. The rpm downloaded OK, installed with zen, and all the messages said it was OK, but trying to open YaST and select Hardware > Printer it hangs at 4%. Has to use Kill to stop it.
Removed /var/lib/YaST2/ppd_db.ycp, and removed the installed yast2-printer-2.14.17-3.2, and installed smart. Then installed yast2-printer-2.14.17-3.i685 with smart, the used YaSt to re-install my network printer, which is on an FC6 box. I set it with no sharing and no local filtering, via an SMB share (I have to provide access for Win98 & XP) and the test worked fine, so I have my network printing back.
I still don't know why installing the downloaded yast2-printer-2.14.17-6.rpm didn't work, but this workaround works fine.
