From reading the docs in the SDK and searching the web communities, I have successfully coded routines in MS Access vba to fill a fillable pdf (even with check boxes), save the file, re-open the file for display and print only select pages. The one thing I cannot find anywhere is a way to tell the pdf to print in duplex mode. I have a client with various 2 page fillable pdfs. The client does not want to have the pdf opened and use the Adobe software functionality to control the printing. The client wants the files to print silently, but to print in duplex mode to cut paper usage in half. All user are licensed for Adobe Pro/DC. Does anyone know how to accomplish this?
