Open PDF Report and Print

Is there any way I could include a button on a form to open the related PDF Report (up to here OK) and print it (to default printer) without having to click the print button or CTRL+P?

I looked in the fpdf docs (the lib that’s used) but there nothing to be found there, so I guess it’s not possible.

I think using Javascript to print a PDF may be an option. This is something i want to include myself. If i come to a conclusion on this i will post here.
Some info here in case you want to start something:

Not really sure how the PDF Report Form works, haven’t tried it yet. However if it’s possible to execute JavaScript code above into a PDF when generated, it can be automatically printed to a default printer when opened.
