What i've been trying to do.
With vba I did save two pdf files from two different applications into one folder.
One is always one page the other can be multipaged.
I need those two pdf printed out one one single paper. Duplex printing.

-I tried to combine them with script off Ken Puls which partly succeeded. The combined file looks like it had been zoomed with just a small part visible.

-I tried to embed them in excel but this gave problems with multipage pdf's.Only the first page is vissible. Embedded as webrowser the multipage is visible but cannot be printed.

-I tried to select both pdf files and sent it as one task to the printer. (what you do in explorer (ctrl) select two files. Rightmouse click, print).
Unfortunatelly the sendkeys are no longer supported.

If anyone knows a way to get it done to print the two pdf files duplex on one page. Please let know. I am stucked here for days.
Every lead ,hint is welcome.
