That seems completely against the idea of verification, so it's probably deliberate to stop ticks printing. Anyone could put a tick in their document, and it would be on the paper. Signature verification is an online-only process, needing to be actually checked every time. Anything else is like adding a sticky note saying "Ok - it's fine - just trust me on this one".

First of all, integrated PDF signatures whose appearances change according to the validation state have been deprecated more than 15 years ago and in PDF-2 have been forbidden. Thus, you shouldn't expect any software to support them still.

Furthermore, those changing signatures had been defined so that in the saved PDF the not-yet-verified symbol, the question mark, is stored. Consequentially, that question mark should also appear in print-outs.

Be aware that a printed digital signature is meaningless, whether it appears to be validated or not. The only way a digital signature has any meaning is if it can be verified against a public key, and that's not possible once you print it. At that point it's nothing more than an image.
