Dear Maintainer,
I have been many problems with this release:
- a wrong public key that avoid to install the plugin (solved by download
it from HP and import with gpg --homedir ~/.hplip/.gnupg --import
hplip-publickey.asc);
- bad permissions for ~/.hplip
After I have solved those up, both scanner and printer seem to work, but the fax will not.

I have checked if I have missing some Python libraries, but don't seems.
The multifunctions has sent fax before and the line is ok (the destination
number in the test above is a fake).
I have tried to clean ~/.hplip, purge and reinstall hplip and cups.
The "missing" or "incompat" in hp-check (as hp-doctor too) have no sense
(cups is up and why I need *.dev or qt4 packages?) and however they are
deb.
Thanks
Stefano
