Google cloud printer window pops


Something funny came up when I start to use Quickform nodes. When I run a workflow and choose f.e. ‘List Box Input: Interactive View’ then after 2 secs a window pops up stating that a new Google cloud printer was discovered, which I can choose to add. There is also the option ‘Do not show this anymore’ but this has no effect.

The ListBox Input windows pop up as Google Chrome windows, presumably this has something to do with it? I am running this on Ubuntu 16.04 LTS, Knime 3.5.3.

Has anybody come across this before?
