Public bug reported:
Setting Python 3.5 as the default for python3 breaks printing over
HPlib.
Steps to reproduce:
sudo -s
cd /usr/bin
rm python3
ln -s python3.5 python3
...
print something using a hplip enabled printer -> printer stopped
rm python3
ln -s python3.4 python3 # this was the default setting after installation
...
printing resumes
I also observed a crash in the HPLip libraries which indicated the cause
being in the hplip package. (this was not reproducable though)
