Emitted when printing is requested on @web_view, usually by a JavaScript call,
before the print dialog is shown. This signal can be used to set the initial
print settings and page setup of @print_operation to be used as default values in
the print dialog. You can call webkit_print_operation_set_print_settings() and
webkit_print_operation_set_page_setup() and then return %FALSE to propagate the
event so that the print dialog is shown.
You can connect to this signal and return %TRUE to cancel the print operation
or implement your own print dialog.
