Print to PDF Subform

Hello,

I have 2 hidden subforms with expandable fields.  If one or both subforms are visible, I'd like a button to print to pdf the visible subforms only.

Can't really indicate page range because they could expand to multiple pages.

This is what I have on a click event so far.

pp = event.target.getPrintParams();

pp.interactive =pp.constants.interactionLevel.automatic;

pp.printerName ="Adobe PDF";

pp.printAsImage =false

event.target.print(pp)
