Hello,
I noticed so far that Gwenview is not list at all on the GSoc Page:
http://community.kde.org/GSoC/2014/Ideas

However I noticed a couple of people[1] asking in #kde for jobs on Gwenview.

So I went ahead filled a number of bug reports and merged all print related in this meta bug:
Bug 332213 - Meta bug: For Print Issues in Gwenview

Now I was wondering if this would make up for a GSoc or a 40-day job and thus could be up on http://community.kde.org/GSoC/2014/Ideas?

And ofc there would also be a developer needed to mentor this...

cheers

Some were (possible) GSoC students, but some came from an university and were looking for a "40-day" work (see "Query: Possible code contribution" on kde-devel).
