Heh... you're misunderstanding how CUPS works :-)
That directory is only the official repertory for *installable* PPDs.

Now that the PPD is there, it will be used next time you install it.

You can now 

 a) either install the printer again, using this PPD (actually, a simple
    "lpadmin -p printername -P /usr/share/cups/model/HP/<ppdname.ppd.gz>"
    should be enough;

 b) or just copy the PPD file to "/etc/cups/ppd/<printername.ppd>"
    where the *installed* PPDs are, and it should work
