wireless networking - Can a Time Capsule join a third-party Wi-Fi router as a client, and still bridge traffic to/from its Ethernet port

Can an Apple Time Capsule join a third-party Wi-Fi router as a client, and still bridge traffic to/from its Ethernet port?

Maybe same question but can a Time Capsule 1TB use a LAN printer? So it doesn't have to use the internet.

I this possible?

So Wi-Fi modem/router (Cisco) ------Wi-Fi----TC-----Ethernet LAN printer
