I'm trying to generate a PDF that can be viewed interactively in Adobe Reader, but also, upon printing, selects different paper trays based on the page. (Some pages are supposed to use stationery, whereas other must not.)
PDF itself apparently doesn't support this form of metadata by design (as discussed e.g. here), but apparently, JDF is an appropriate format, and can be embedded as XML in the PDF.
What's less clear to me is if Adobe Reader does anything useful with that metadata: if a PDF with embedded JDF information is printed, does it parse the JDF and choose paper trays? Can I use PDF portfolios for this purpose instead?
My goal is to both let the user view the PDF in Adobe Reader interactively, and, upon printing, automatically selecting different paper trays.
(The far less convenient alternative would be to write a custom app to do the printing.)
