Despite the significant changes in how we create and consume films and books over time, we often maintain a rigid boundary between the two mediums, much like in the past. However, firmly fixed definitions of these mediums make it difficult to use them flexibly. 《How to Shoot a Movie With a Printer》 suggests distrusting and questioning these definitions as a starting point for freely navigating and utilizing different mediums. What does it mean to be “film-like” or “book-like”? “Filming with a Printer” looks like a book in the conventional sense, but it is a film. Viewers may argue, based on its characteristics, that “this is not a film, but a book.” However, the more they argue, the more they will realize that these characteristics are not exclusive to films. This film or book blurs the definitions and boundaries of mediums we have long believed in.
