Sets the number of pages in the document.
This must be set to a positive number before the rendering starts. It may be set in a [[email protected]:
GtkPrintOperation:begin-print] signal handler.
Note that the page numbers passed to the [[email protected]:GtkPrintOperation:request-page-setup] and [
[email protected]:GtkPrintOperation:draw-page] signals are 0-based, i.e. if the user chooses to print all pages, the
last draw_page signal will be for page n_pages - 1.
