Page Setup in the Gimp 2.8 menus – Imposta pagina in Gimp 2.8

Solution by GJK:  Copy the print.exe from an old Gimp (for me 2.6.12)in the main plugin folder of Gimp and overwrite the print.exe from 2.8. After that you have the Page setup back and printing will work. You might have to change the image size in the properties tab of the print dialog though.
System: Win XP 32

This trick is ok for me!
