This is not a bug of the Ubuntu package of HPLIP but of HPLIP itself (note also that the newest Ubuntu package is only of version 3.11.1 and not yet 3.11.3). Therefore I am closing the bug task for the Ubuntu package and adding a task for the upstream software.
To the HPLIP developers at HP, somewhere in the transitions of Python 2.6.x -> 2.7.0 -> 2.7.1 type conversion got more restrictive. Please check with the newest versions of Python.
