We currently support printArea only for Xlsx and Xls. I will treat this issue as a feature request rather than a bug. I offhand have no idea how difficult it might be to implement - parsing the print area can be tricky (though not in your examples nor, I'm sure, in most of the applications that use it). Once that is done, we would need to integrate it with the Html Writer (the output of which is used by Pdf Writer). And, even when that is done, I'm not sure if we can satisfy the additional options (e.g. HorizontalCentered). At any rate, I'll put it on my to-do list, but I don't expect that I would get to it any time soon.
