Effective and vey easy to use. I use it to print a book after editing it with OO Write. Formated pages in mirror, and then print to a pdf file. Then assembled the booklets with bookletimposer, and finally printed the end files with pdf viewer.
Avec une imprimante recto-verso automatique, Bookletimposer est parfait pour imprimer des documents sous forme de brochure au format A5 à partir de feuille de papier A4.
This worked well for me. It creates a new pdf with the pages in booklet order - ie when you open the new pdf and print it out (on A4) then fold pages in half you have an A5 booklet. Thankyou.
