If she's not a virgin, you should see eggs/larvae within a few days. I would go ahead and give a frame or two of capped brood if you can spare it so that they have a quicker availability of workers to cover the new brood the queen lays. She will probably lay quicker if she knows there are sufficient workers to care for the new brood. I feed my new swarms and it also gives them a motivation to start producing.
If she's a virgin, you should still start seeing eggs in a week or two.
