PrintOperation.addOnPaginate

Emitted after the #GtkPrintOperation::begin-print signal, but before the actual rendering starts. It keeps getting emitted until a connected signal handler returns %TRUE.

The ::paginate signal is intended to be used for paginating a document in small chunks, to avoid blocking the user interface for a long time. The signal handler should update the number of pages using gtk_print_operation_set_n_pages(), and return %TRUE if the document has been completely paginated.

If you don't need to do pagination in chunks, you can simply do it all in the ::begin-print handler, and set the number of pages from there.
