I don't think the calculator ROM code can handle the two operations simultaneously, so I'm guessing the card is either ignored until printing completes or it is just passed through the reader.

That would be printing a program while you overwrite it with another program:-)
Not too useful IMHO.
However if you want to know what happens just try;-)
