This bug has been reported upstream since July 2015 but despite messages that claim it is fixed, it really isn't !
https://bugs.launchpad.net/hplip/+bug/1480152
I renewed the bug yesterday...

By the way gentoo and debian have applied a patch, I have successfully tested on 3.18.4-1.

Is it possible to include the attached patch (sixext.patch) in arch package as well until upstream make up their mind and fix this annoying bug ?

Additional info:
* package version(s) 3.18.4 (and previous)
* config and/or log files etc.
attached hp-set.log : the result of the command hp-setup -i -bnet -ldebug


Steps to reproduce:
- connect an HP Photosmart C6280 printer (I guess it is not the only model that failed) on local network (ethernet in my case)
- power it on
- issue the command on arch computer (attached to the same network obviously) : hp-setup -i -bnet
=> it fails with the UnicodeDecodeError exception traceback above
