Comment 2 for bug 525901

When I got that error I used packages just from my package manager. I simply plugged in the printer and the system told me that the printer needed a proprietary plugin and offered me to download it. It didn't work, then I tried it several times with HPlip-gui and it didn't work either. BTW I'm using 64-bit Ubuntu.
I have installed these packages:
hplip 3.9.8-1ubuntu2
hplip-data 3.9.8-1ubuntu2
hplip-gui 3.9.8-1ubuntu2
python-qt4 4.6-1

Then I installed HPlip (3.9.12) from the source code provided on the website. The installation process uninstalled all hplip packages except for hplip-data and the problem was fixed. If there is no problem with hplip-3.9.8.tar.gz there must be a problem in the package, where else?
