Why don't you wanna create CloudPrintPromo class that would render template into
an element that user of the class provides and would collect all the clicks and
persist it's state?

Tempting. The first iteration wasn't very complex so it was fine including it in
print_preview.js, but now it has grown a little more complex.

I think it makes sense to move it into separate class, but in a later CL. Before
I do that, I want to abstract some common behavior for all print preview dialogs
(e.g. Destination Search dialog) into a common base class, and have the promo
widget inherit from that.

O.k. sounds good, can you add a TODO for now?
