Common roadblocks:

• Printer stuck on old SSID or 5 GHz only when it needs 2.4 GHz.
• WPA mode mismatch or hidden SSID quirks.
• Router isolation settings (AP/client isolation) blocking discovery.
• Drivers or AirPrint services not installed on the computer/phone.
• Weak signal in the corner where the printer lives.

What it might be (likely causes)

• Band/SSID mismatch
