Having just come off of 5 years in anti-spam, an idea like this one strikes me as hilariously dumb. Here’s how I see this one playing out:

Printing noise from the kitchen during Grandma’s weekly bridge game…

Grandma: Ooh, I must be getting some new pictures from my daughter of the grandkids on their vacation to DisneyWorld!

Four women cozy into the kitchen to see a piece of porn image spam printing out…

Grandma’s friend: DisneyWorld sure has changed since last time I was there…

Economics, people. Economics.
