Many priinters not working hplip NEEDS update in ubuntu 14.04LTS

hplip on Ubuntu 14.04 is hplip 3.14.3
But the printers sold nowadays need 3.15.9

This is a BIG problem ! You can't ask normal people in a normal office to go to
http://hplipopensource.com/hplip-web/install/install/index.html
and install it in a so ugly terminal method lol

Please, we need 3.15 !

thx
