Without delving too deeply into to technical complexities of TLS/SSL, the warning that you see is entirely benign and expected...
Each time that you power-cycle your printer, it automatically generates a new self-signed Certificate with which to encrypt the printing connection. Being self-signed and without a trusted-root, your iPad (and other devices) cannot validate the authenticity of the Certificate - and for this reason you will see the warning that you describe.
That said, selecting Continue should allow you to click-through any associated security warnings.
