Embeded flash or flashpaper for store to Print ONLY not download

I basically am setting up an e-commerce site and there will be content in a flash for them to preview so they can't save it without buying it. I want to have them able to purchase the content in the flash and have acccess to it for printing for ONLY 3 times. Is this possible? I am also open to ideas for this that are similar but perhaps more functional? Feel free to contact me about this ## Deliverables I don't know how to do this, but i need to figure out to incorporate it into a joomla site
