using newer HP printers - hplip is old

Does anyone have a recommendation in how to incorporate
a newer HP printer into CUPS under RHEL 5.2?  The version
of hplip installed is hplip-1.6.7-4.1.el5_0.3 which does not
contain, say, the HP Color LaserJet 4005 while the version
of hplip on Fedora 9 (hplip-2.8.2-2.fc9) does do so.  This
is a generic issue, not specific to the example printer.

One cannot simply add the fc9 repo and install hplip from
it- there are far too many dependencies.  Plus, I prefer a
standard RHEL update process, if possible.
