CentOS - Apr 2014 - Why are hplip and hpijs always so back dated?

My fully patched CentOS 6.5 system uses:
hplip-common-3.12.4-4.el6_4.1.i686
hpijs-3.12.4-4.el6_4.1.i686
hplip-libs-3.12.4-4.el6_4.1.i686

My wife's printer becomes supported at 3.13.somethingOrOther
and the current release is 3.14.something.

Why are we so far behind?

I realize that I can download the latest, uninstall the RPM versions
and compile and build and install the source copy.  If I was going
to follow that route, I would prefer to build an rpm and install
it normally.  I have been looking on the Internet and not found
anything to turn the release from HP into a binary RPM.
(That does not mean it is not there.)

I know it must be doable since there are rpm's in the repositories.
My skill with RPM's is somewhat limited, but does anyone know
of a set of instructions and a spec file that could be used to 
get started on this process?

Thanks in Advance

I've never tried it with hplip, but many rpms can be updated by simply
downloading and installing the srpm for the version that you're trying to
update from, putting the newer source file into rpmbuild/SOURCES, updating the
spec file in rpmbuild/SPECS, and then typing: rpmbuild -ba myfile.spec

The source rpm will have a spec file included.
