If we change the softlink to point to another python version, we need to reinstall hplip. Did you do that?
Try resinstalling HPLIP and check if things work.

Title:
  printing will fail with python3.5 set as default

Status in HPLIP:
  New
Status in hplip package in Ubuntu:
  New

Bug description:
  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)
