Well, printing plaintext is the definition of not secure... However,
it's not too hard to create a plugin/add-on/script for this.

One would argue that you could print b64 encoded encrypted password
("armored" in gpg terminology). And then recover them using OCR, but I
wouldn't trust such thing as a good backup.

All in all, I would go for creating the plugin for pass dump as you said.
