Solving problems with python-dev package installing hplip 3.14.6 on Ubuntu 12.04.4

I found that the latest update of Ubuntu 12.04.4 does not include precise-updates and this is necesary to install the latest hplip 3.14.6


Just add these lines to /etc/apt/sources.list

deb http://mx.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb-src http://mx.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
