I am using Hardy Alpha 4 and still have this problem.
Click on the "browse to file" button at the error dialog shows an HP Fax PPD archive in the /usr/share/ppd/hpijs/HP/ directory but choosing it brings back another error:
"error: Incorrect fax PPD file. The fax PPD file must have a nickname of 'HP Fax', not 'HP Fax - HPLIP 2.7.12'."
The /etc/hp/hplip.conf file has the following line:
ppd=/usr/share/ppd/hpijs/HP

The /etc/hp/hplip.conf file has the following line: share/ppd/ hpijs/HP
ppd=/usr/
Instead of: share/ppd/ hpijs/HP/
ppd=/usr/
I tried both with the same result.
