Printing from Adobe Reader

Hi,

I am merging multiple XDPs (using invokeDDX) to create a merged PDF output (using generatePDFOutput).

The issue that I have is when I print the generated PDF from Adobe reader, it doesn't detect the varying size of the pages. It prints all pages on the paper size of first page. Unless I manually check the "choose paper source by PDF page size" checkbox on the print window. Our users don't want to check/uncheck that check box.

Is there a way I could have the print default to this setting? So that it detects the varying page sizes and prints accordingly on respective pages.

Thanks,

Phoenix
