I have the new complicated! Windows 7
Is there a template for making a book using landscape A4 to a folded A5
booklet? with instructions for printing on the overleaf to remove all the
white space on the back of the sheet?
Or would I have to create it manually?
If I have to create it manually how do i set the margins and pages so that
the text only goes on one half of the page until I wish to write on the other
side?
Im stressed and would like to refrain from destroying my laptop!
