The EcoTank family (ET-2850, ET-3850 and the L-series - L3250 and its siblings) shares one setup story: Windows can often print to them with a basic driver, but scanning, Wi-Fi setup and ink monitoring only appear with Epson's own package. If your EcoTank prints but won't scan, or is not detected at all, the fix is installing the right package in the right order.
Quick answer
Download the full driver and software package for your exact model from Epson's official support site (search the model, e.g. "ET-2850" or "L3250"). Run it BEFORE connecting the printer, and let the installer handle the USB or Wi-Fi connection when it asks. The package brings printing, Epson Scan 2 and ink monitoring in one pass.
Windows' built-in driver makes the printer print - and nothing else. Scanning and maintenance live in Epson's full package.
Connecting USB before installing the package creates a half-configured device that the installer then stumbles over.
The printer joined the 2.4 GHz network (or a guest network) while the PC sits on another - discovery fails even though both are "on Wi-Fi".
Moving to a new PC or reinstalling Windows leaves stale entries that block the fresh setup.

Yes - current Epson packages support Windows 11 and 10. For an older EcoTank whose page lists only Windows 10, that same package installs on 11 in practice; install it the driver-first way described above.
For printing and scanning from a PC - no, the driver package plus Epson Scan 2 is enough. The mobile apps matter only for phone printing; skipping them changes nothing on Windows.
