section expert, select the group header and footer and see if the new page before or new page after is ticked off or is using a formula

also are people intended to drill into a group to print?
Otherwise since these are mixed groups you would likely have multiple "printing directions" for one print job.

I am not familiar with EFI.
I am making a number of assumptions here that might be confusing to the problem.
I assumed you were including this text so that when the user went to print the report they would choose the 'correct' way to print it.
I am confused because each group may require a different way to print. To further compound it two groups with different printing requirements might be on the same page.
When I suggested drilling into the report it opens a group into s new report tab and you can print that separately from the larger group which deals with the confusing aspects above.
I still don't think this is entirely what you want but you can set the text using group criteria something like this:

if Minimum({wi_route.wi-r-p-printf},groupfieldhere) = TRUE and Minimum({wi_route.wi-r-p-printr},groupfieldhere) = TRUE Then
     "Two Side Printed"
Else
    If Minimum({wi_route.wi-r-p-printf},groupfieldhere) = TRUE Then
        "Surface Print"
    Else "Reverse Print"

Thank you very much DBlank! I will try your suggestions and hopefully they will work!
