I need to print a report to a duplex printer and make shure that the sheet

of paper is ejected after each group. As a group can need 1 to 4 pages, I

need to eject the paper or making the number of pages printed for each
group an even number of pages.

Preferably I would like the report to print w/o extra ejects or pages when

printing on a non-duplex printer.

I know how to find the numer of pages that a group will need (using
calculations in group footer), so I just need a solution to get the 'extra

page' added when I need it.

Thanks for all the help I get
