Just thought I would pass on how I solved this. In the end it was fairly simple
The printer I was testing with I simply created a copy of the printer and changed the PAPER SOURCE 1 to *LEDGER
The production printer was a little trickier. I created a copy of the printer and changed the PAPER SOURCE 1 to *LEDGER
This caused the printer to choke.
I found a WSCST from Xerox. This allowed the printer to print the overlays, but the backside overlay was upside down.
I then changed the WSCST flipping a couple of parms as noted in the source and WOO HOO Success.
Both Xerox printers, but different models.
