The Epson WF-7520 was listed as a supported model in a July 01, 2022 version of Apple's About AirPrint article, but is not mentioned in the latest About AirPrint - Apple Support. This could indicate that this model only has been discontinued by the printer manufacturer, or it could possibly mean that the printer firmware is not compatible with the latest macOS version(s). Have you checked whether a printer firmware update has been made available?
Normally, an AirPrint model should work without the need for additional drivers, if the printer is connected to the same network (Wi-Fi router) as the Mac computer.
Since AirPrint works with wireless (Wi-Fi) or wired (Ethernet) printer connections, you could choose to wire the WF-7520 by Ethernet to one of the LAN ports of the router (instead of using Wi-Fi) as a test.
Please note that the WF-7520 connects via the 2.4 GHz frequency band.
With some modern routers (with "smart" device discovery and automatic wireless band selection), renaming/splitting bands may be needed. In such a case, an Ethernet-connected printer could be advantageous.
A USB connection typically requires drivers (exceptions exist).
