saving a page

Hi!
I am generating a bill retreving certain data from the previous page.
Could you please tell me how can I save a bill when a user hits a button?
In otherwords, I need to save each bill generated, when a user hits the Print command from
<a href=javascript:PrintPage()>Print </a>
Please help!
Thank you

save where? what format?

I need to save in HTML format, same as a WebPage.
Thanks a lot Memnoch1207

Is it possible to get a Save As dialog box when a user clicks on the button?
Please help!
Bye
