This is an idea that comes up here quite often. In theory it could be done
but there are various obstacles and I don't think anybody has implemented it.
You would probably be better off hiring a logic analyser for a couple of days.

There isn't really anything printer specific in the parport code. It is also
used for external storage devices (Zip, SyQuest etc), pocket ethernet
adapters, digital cameras, PLIP links and teletext receivers to give a few
examples.
