I am doing a website that needs to only let the customer print out what they bought 1 time. There are websites that currently do this and they mentioned  Adobe Flash Player, Adobe AIR and the Sheet Music Plus AIR application.We would need to block programs like adobe distillation and any virtual printers while only allowing an instant print after purchase.I am not an adobe air developer. Would their be any other ways to accomplish this and what would be the easiest. Thank you.Would their be a way to not allow printing to a virtual printer ie adobe pdf?
Allow visitor to print something they bought only 1 time
