If it's supported in XFRX that should be the cleanest and simplest approach.

>Thanks Al, had this project on hold just getting back to it. I have XFRX and from their help file "Appending generated output to existing PDF Documents" so this might work!

>>>Hi all,
>>>
>>>I have a bunch of PDF files that need to be printed thru my customized software, the customized software knows the address where it needs to mail so I want the address to print on the backside. So basically my program will print the PDF and then duplex it and print the address on the back. If it was printing 2 foxpro reports I know this is totally doable but here I'm printing a PDF file and somehow I have to duplex it and make it print my report on the backside.
>>>
>>>Any ideas?

>>I'll assume you're working with a printer that can duplex print. By default, if duplexing is enabled, the printer will only duplex print a single document/print job. So, saying that printing 2 VFP reports is totally doable is not true; by default you'd get 2 separate pages printed on one side of each.

>>The trick is to combine the existing PDF and your custom address page. I can think of a couple of options:
>>
>>1. At the document level: Print your address page as another PDF, then merge the two PDFs, then print the combined one
>>
>>2. At the print job level: Print the primary PDF to a file, print your address page to another file, combine the two files, then dump the combined file directly to the printer
