Do you mean that it is not working when you preview it or did you mean that is not working when you embed it in email body?
If you refer to report embedded into email body then you need to remember that only content from section between <Body></Body> tags is placed in email and you have to consider email clients limitations (which is not related to NPrinting but purely to email clients capabilities of interpreting html)
When using your html code this is what i get on Preview, is that what you wanted?:
