print_run_page_setup_dialog

Runs a page setup dialog, letting the user modify the values from page_setup.

If the user cancels the dialog, the returned `GtkPageSetup` is identical to the passed in page_setup, otherwise it contains the modifications done in the dialog.

Note that this function may use a recursive mainloop to show the page setup dialog. See [func@Gtk.print_run_page_setup_dialog_async] if this is a problem.

Parameters:

parent	transient parent
page_setup	an existing `GtkPageSetup`
settings	a `GtkPrintSettings`

Returns:

a new `GtkPageSetup`
