Can't find printer connected to Repeater/AP

[nexigen]

How can I find things on my Access Point/Repeater?

I'm using Windows 10 and I'm connected to my network via internet router. I have 3 computers on this network. I have a Repeater/Access Point that contains a Printer and couple TV's. I'm trying to set my Printer up but nothing is discovering it, can I go about it manually or explore that Access Point somehow? When I login to my Router I see the IP of the Access Point.

What is the model of the AP/repeater? How is it connected back to the main router (wired/wireless)?

TL-WR810N - wired connection to router.

My first guess is that you don't have it configured as an access point. If it were configured as a router, then the devices on the "LAN" side would not be visible to you on the "WAN" side.
According to the manual the term that is used is "Working Mode" -- See section 4.3 in the manual -- https://static.tp-link.com/res/down/doc/TL-WR810N(US)_V2_UG.pdf
