I can't connect my Epson RR-600W RAPID scanner to my Mac

Well clearly you have an internet connection, otherwise you wouldn't be posting here. What it would seem to me is either the scanner has its own built-in internet access which is not set up right, on its own panel and it needs to be hooked up with your WiFi, or it needs to be hard wired to your computer to get internet access to establish updates for the scanner's own built-in software.

Most scanners offer USB connections to the computer to get direct connectivity.

https://epson.com/support/epson-connect-printer-setup-for-mac-os-x is a software which usually can find the correct driver, if your device is hard wired to your computer. If you can program WiFi to the device while hard wired to match the Mac's built-in WiFi network connection, or manually program it on the device's LCD to be connected to the same WiFi, the device can use the AIrprint functionality to connect over WiFi.

Is this the page with the link you are trying to download?

Be sure to select macOS 12.x from the dropdown box because its "automatically detected" feature was not working correctly when I tried it.

Then, click the blue Go button, and click the blue Download button that appears on the next page.

Assuming you get this far describe what happens next.
