I think it depends, if it prints your conscious idea, then it would still be your story, but the art would not be yours(in terms of drawing).
If the printer writes the plot for you, then it would be as you said. Being part of an algorythm.
Also is important to know if the printer would draw with your skill level and if it projects the first idea it comes out of your mind.
So if you get distracted while printing, it may accidentally create a weird image: the first half is your comic, and the other half is that videogame you can`t wait to play. (or they get mixed or something)
