What you are trying to do is typically accomplished wih your printer software, under Properties in the print menu, you may be able to set it to 'Two-Sided Printing', the printer software would thwn instruct you on how to reinsert the paper.
If your printer does not support this than print the Odd pages and rotate and reinsert the paper, then print the even, you may have to play around a little bit to get it right, so try it with pages 1-5 before you kick out 25 pages and relialize they won't line up.
