Connecting printer via RJ45 to wireless network

[Marcin2023]

I have non-WIFI printer connected via RG45 cable to TP-LINK 902 router.
The TP-LINK router is configured with static IP for the printer, and it is configured as client for a wireless Access Point for the main network.

A computer connected to the TP-LINK's own WIFI can see the printer.
But a computer connected to the AP cannot.

How can I print to the printer connected to the TP-LINK from computers connected to the AP?

The only thing I could think of is if the AP has layer 2 traffic isolation enabled. That is the only thing I have seen block traffic in the way you describe. Can you ping the TP Link from the AP? Also can you ping the printer?
