gtk:print-run-page-setup-dialog-async (parent page-setup settings done-cb)

parent -- a gtk:window transient parent, or nil
page-setup -- an existing gtk:page-setup, or nil
settings -- a gtk:print-settings object
done-cb -- a function to call when the user saves the modified page setup

Runs a page setup dialog, letting the user modify the values from page-setup. In contrast to the gtk:print-run-page-setup-dialog function, this function returns after showing the page setup dialog on platforms that support this, and calls done-cb from a signal handler for the "response" signal of the dialog.
