upper part of printout is missing

[D-nl-k]

Linux Distribution and version.
===============================
Kubuntu 14.04.3

Printer make/model.
===================
HP Photosmart 6520

Output of 'hp-check -t'
=======================
Attached you find the output of 'hp-check -t'
When running hp-check it tells me (on stderr):
warning: ubuntu-14.04 version is not supported. Using ubuntu-13.10 versions dependencies to verify and install...
warning: HPLIP-Installation: Auto installation is not supported for ubuntu distro 14.04 version

Explanation of the problem:
===========================
It is impossible to print a sheet up to it's upper border.

Even worse: If I set up a border that's too small I don't get a warning, but on the printout the topmost part is missing (see the attached printout of a web page. The address line is printed only half)

The setting "borderless print" does not help, too. Paper size is A4.

Steps to recreate the problem.
==============================
- Attach printer to the system
- print e.g. a web-page

Hi,

You are required to use the updated version of HPLIP-3.16.7.

Download and install the latest HPLIP from http://hplipopensource.com/hplip-web/install/install/index.html

Report back in case the issue continues.

Thanks,
Kritika

I just upgraded to the mentioned version.
The error message "ubuntu-14.04 version is not supported" is gone but the printing issue still persists.

Attached the new output of hp-check -t.
