Hypothetically, the car might be able to print its own systems report during manufacture. This might not be an entirely far-fetched theory given that a car contains numerous independent computers networked together and not all of them have direct access to a display.

Another possibility is that a "printing" metaphor is being used to communicate certain things between the various car computers. For example, if there's an engine fault, the engine's computer might "print" the fault report to the center console computer. On a modern BMW, the centre console computer shows a log of faults as well as a full service history and upcoming servicing requirements.
