I've connected to the Epson printer's Wi-Fi network, but I can't print. Why?

Connecting to the Wi-Fi network isn't enough; you need to *add* the printer to your laptop. Go to your laptop's 'Devices and Printers' (Windows) or 'Printers & Scanners' (macOS) settings. Click 'Add a printer or scanner'. Your laptop should detect the Epson printer. If it doesn't, you may need to manually add it using the printer's IP address (found in the printer's network settings).
