How to restrict pdf printing on a condition

Question

Hello,
We generate the pdf and distribute it to the user immediately. I've a business requirement to allow the user to print the pdf a maximum of 3 times. I was able to add the javascript to the pdf to make a webservice call that would keep a track of prints(by getting the pdf blessed by the livecycle readerextensions). Now, I've two questions :
1.How can I disable printing on the pdf document when max number of reprints is reached?
2.The pdf throws security warning when it makes the webservice call. Is there anyway to supress it?
Thanks in advance for the responses.
Feroz.

Thanks Neerava. I tried compiling the project in the link you provided and I'm getting the following error:
