In my ASP.NET application,
if I want to control my receipt printing,
it means user can only print once,
duplicate copy is not allow.
My concern is web application is run on browser,
and as long as everything can display on browser,
user can simply save the HTML file and print as many as they want.
So is there any way to solve this problem?
