If your image is digital, why print it? A digital print is a paper replica of a graphic emulation bit stream. We already have enough mass produced, disposable products. A potential million sheets of paper as a temporary repository of a digital image seems so archaic. It should take advantage of what it is - a bit stream that can be transmitted via wire or even thru the air to wherever, and can then be displayed on devices like wall screens, cell phones, etc.. The creators of digital images - call them whatever - need to think outside the box and use the power of their medium.
On the other hand, for those of us who still use film, a print is a necessary corollary of a negative. It is not part of the throw-away economy, rather we make every effort to ensure its relative permanence. Back to the original topic - it is a unique medium, worthy of collection.
