Printing OpenLayers 3 Map

I have a couple of questions. Firstly, I want to print my OpenLayers map, I can do this using the Export example (http://ift.tt/1IkzzKn). However, for instance, can I set the extent of the printed map, or can I add a title?

I also have the Highcharts chart in my WebGIS. What I want is to print both the chart and the map in same PDF. Highcharts also offer printing. The tricky part is combining both printing functions that I have. Do you know any way where it is possible?

I am also adding a screenshot, to let you understand better.

Thanks for the help!
