Much better this way. I have implemented it as follows now (in the 
Debian SVN repo, release 3.10.6-1ubuntu7):

- libsane-hpaio recommends hplip.
- The file /etc/hp/hplip.conf moved from hplip to libsane-hpaio. This
  makes libsane-hpaio work without hplip.
- As hplip needs /etc/hp/hplip.conf hplip depends on libsane-hpaio
  again, as before (It was even wrong to lift this dependency as
  /usr/share/hplip/data/models/models.dat was already in libsane-hpaio).

Now it is assured that libsane-hpaio always works and minimum 
installations are possible.
